Photodegradation and defect passivation of hybrid metal halide perovskites are still challenges toward related highly stable optoelectronic devices such as solar cells. Herein, we show that photodegradation and defect density can be drastically reduced in 2D/3D perovskites by engineering the conditions for carrier delocalization. For this purpose, conjugated, partially conjugated and non-conjugated spacer molecules of similar sizes as well as n values have been systematically changed in 2D/3D perovskites based on archetypical MAPbI₃. The decrease of calculated HOMO-LUMO gaps of complexes with spacer molecules (E_HL-complex) correlated well with the decrease of the Urbach energy, the decrease of the trap-state density, and the strong reduction of photodegradation of 2D/3D perovskite films, whereas the photodegradation was practically independent of the n value for conjugated spacer molecules. In addition, the short circuit current density (J_sc) and open circuit voltage (V_oc) of the prepared solar cells increased with decreasing E_HL-complex; hence, maximum initial values of J_sc and V_oc larger than those of identically prepared reference solar cells based on 3D MAPbI₃ were reached. We also demonstrate that the photodegradation of solar cells decreased monotonously with increasing initial power conversion efficiency. Thus, delocalization by optimum coupling of electron wavefunctions between conjugated spacer molecules and binding moieties at the perovskite enhances defect passivation and strongly reduces photodegradation in 2D/3D perovskites.

混合金属卤化物包晶的光降解和缺陷钝化仍然是太阳能电池等相关高稳定性光电设备所面临的挑战。在此，我们展示了通过对载流子脱焦条件进行工程设计，可大幅降低二维/三维包晶的光降解和缺陷密度。为此，我们系统地改变了基于典型 MAPbI3 的 2D/3D 包晶石中类似大小和 n 值的共轭、部分共轭和非共轭间隔分子。计算得出的带有间隔分子的复合物（EHL-复合物）的 HOMO-LUMO 间隙的减小与厄巴赫能的减小、阱态密度的减小以及二维/三维包晶薄膜光降解的强烈减弱密切相关，而共轭间隔分子的光降解实际上与 n 值无关。此外，所制备太阳能电池的短路电流密度（Jsc）和开路电压（Voc）随 EHL-复合物的减少而增加；因此，Jsc 和 Voc 的最大初始值大于基于三维 MAPbI3 制备的相同参考太阳能电池的初始值。我们还证明，太阳能电池的光降解随初始功率转换效率的增加而单调减少。因此，通过共轭间隔分子与包晶结合分子之间电子波函数的最佳耦合实现的去局域化增强了二维/三维包晶的缺陷钝化，并大大减少了光降解。

Photovoltaic (PV) models are essential for energy planning and grid integration applications. The models used for PV power conversion typically adopt physical, data-driven, or hybrid approaches. Different hybrid techniques, combining elements of physical and data-driven methods, have been effectively developed for PV power estimation and forecasting, leveraging the strengths of both native methods. The data-driven approach allows models to account for unmodeled uncertainties and nonlinearities that purely physical models cannot capture. Meanwhile, the guidance of scientific theory makes the models less dependent on data, thereby improving generalization, interpretability, and accuracy. This review paper provides a comprehensive overview of hybrid methodologies for PV power estimation and forecasting. The main available hybridization methods are summarized and discussed under a novel methodological classification into three primary categories: physics-informed machine learning models, optimized physical models, and physics-guided models. Furthermore, these hybrid models are compared in terms of methodology, applications, and elucidating the merits and demerits of different techniques. By offering insights into these hybrid models, this review lays a foundation for researchers in this field and contributes to the advancement of PV power estimation and forecasting methodologies.

Solar distillers are frequently used to desalinate water into drinkable water by utilizing solar energy. However, their low productivity and efficiency have hindered their widespread adoption, especially in dry and isolated areas where freshwater is crucial. Stepped solar stills, which merge a sequence of cascading basins that operate at progressively lower temperatures, are an intriguing idea that aims to improve the performance and productivity of solar stills. This research intends to scrutinize stepped solar stills’ effectiveness, examining their design, operation, and applications. Various configurations of stepped solar stills, such as the number of stages, materials used, and heat transfer techniques, are discussed in the paper. Theoretical and practical investigations into the thermal behavior and heat transfer properties of stepped solar stills are evaluated, as well as the technology’s benefits and constraints. The study also assesses the usefulness of stepped solar stills in different climatic conditions, as well as their potential use in agriculture, industry, and disaster relief efforts. Additionally, the economic viability and environmental sustainability of stepped solar stills are analyzed. In summary, this review paper delivers an in-depth analysis of stepped solar stills and their potential to mitigate global water scarcity. The research concludes by identifying future research and development prospects and challenges in this field.

Conventional solar greenhouse dryers have transparent walls, and the north wall effect can prevent the north wall from receiving solar radiation, making it a conduit for heat dissipation. To reduce heat loss, opaque walls are used on the north side of the greenhouse. However, a comprehensive comparative analysis of solar greenhouses with insulated opaque north walls is lacking. Therefore, this study aimed to investigate the effect of opaque walls on certain thermal performance indicators of solar greenhouse dryers. Three configurations were tested: transparent, insulated northern, and insulated eastern walls. The results show that the north insulated wall configuration exhibits superior thermal performance, with a higher temperature increase (6.67 % to 11 %) and lower thermal time constant (τ = 8.21 s) compared to the transparent wall (τ = 8.38 s) and insulated eastern wall (τ = 9.03 s). The transparent wall configuration displays the highest solar fraction values (97.81 % to 99.31 %) but compromises energy efficiency due to higher heat loss. The insulated eastern wall configuration shows improved thermal cycling stability (TCS = 82.04 %) but lower solar fraction values (95.87 % to 98.2 %). The spatial heat distribution coefficient (h) was highest for the insulated northern wall (2.2868 W/m²K), indicating improved heat distribution. The thermal effusivity (σ) was lowest for the insulated northern wall (8.656 W⋅ S^1/2⋅ m⁻²⋅ C⁻¹), indicating improved heat retention. The coefficient of performance (COP) was highest for the insulated northern wall (0.52), indicating improved efficiency. The study demonstrates the importance of careful design and optimization of passive solar greenhouse dryers to achieve energy efficiency and controlled temperature conditions. This study provides a scientific basis for the optimal configuration of opaque walls in solar greenhouse dryers.

传统日光温室干燥器的墙壁是透明的，北墙效应会阻碍北墙接受太阳辐射，使其成为散热通道。为了减少热量损失，温室北侧采用了不透明墙体。然而，目前还缺乏对采用隔热不透明北墙的日光温室的全面比较分析。因此，本研究旨在调查不透明墙对日光温室干燥器某些热性能指标的影响。测试了三种配置：透明墙、隔热北墙和隔热东墙。结果表明，与透明墙（τ = 8.38 秒）和隔热东墙（τ = 9.03 秒）相比，隔热北墙的热性能更优越，温升更高（6.67 % 至 11 %），热时间常数（τ = 8.21 秒）更低。透明墙配置显示出最高的太阳辐射分率值（97.81 % 至 99.31 %），但由于热损失较高而影响了能源效率。隔热东墙配置显示出更好的热循环稳定性（TCS = 82.04 %），但太阳辐射分率值较低（95.87 % 至 98.2 %）。隔热北墙的空间热分布系数（h）最高（2.2868 W/m2K），表明热分布得到改善。隔热北墙的热效率（σ）最低（8.656 W⋅ S1/2⋅ m-2⋅ C-1），表明保温性能得到改善。隔热北墙的性能系数（COP）最高（0.52），表明效率有所提高。这项研究表明，精心设计和优化被动式太阳能温室干燥器对提高能效和控制温度条件非常重要。这项研究为太阳能温室干燥器中不透明墙的优化配置提供了科学依据。

Particle-based concentrated solar power (CSP) systems have been identified as a high-potential technology for lowering the levelised cost of electricity (LCOE) due to their higher working temperatures, lower-cost storage, and high receiver performance potential. However, limited system-level optimisation has been performed for these systems. Multi-aperture receiver designs allow for more heliostats to be placed around the high-cost tower. Here, a novel ‘cascaded’ receiver configuration is proposed and assessed for the first time, appealing due to its ability to tailor field segments to the sequential temperatures of each receiver. Three configurations, single-aperture, cascaded, and parallel multi-aperture configurations, are evaluated. Results indicate that while the cascaded configuration achieves higher thermal efficiency and a smaller receiver, its higher optical losses limit LCOE improvements compared to the parallel configuration. However, both the optimal multi-aperture systems, using the US DOE costing suggestions, achieved LCOE below 60 USD/MWh, marking significant savings of approximately 6% over single-aperture systems, indicating the multi-aperture particle CSP is a compelling technology for future development.

基于粒子的聚光太阳能发电（CSP）系统因其较高的工作温度、较低的存储成本和较高的接收器性能潜力，被认为是一种极具潜力的降低平准化电力成本（LCOE）的技术。然而，针对这些系统进行的系统级优化还很有限。多孔径接收器设计允许在高成本塔周围放置更多的定日镜。这里首次提出并评估了一种新颖的 "级联 "接收器配置，这种配置能够根据每个接收器的顺序温度调整场段，因此很有吸引力。对三种配置，即单孔径、级联和平行多孔径配置进行了评估。结果表明，虽然级联配置实现了更高的热效率和更小的接收器，但与并联配置相比，其较高的光学损耗限制了 LCOE 的改善。不过，根据美国能源部的成本计算建议，两种最优多孔系统的 LCOE 都低于 60 美元/兆瓦时，比单孔系统节省了约 6% 的费用，这表明多孔粒子 CSP 是一项值得未来开发的技术。

Solar chimney power plants (SCPPs) are gaining attention as sustainable energy solutions, yet their efficiency and energy output have limitations. To enhance these factors, various hybridization strategies are being investigated, such as integrating solar photovoltaic (PV) cells, waste heat recovery, geothermal energy, biomass, thermal storage, and heat exchangers. Among these, the combination of PV cells with SCPPs has shown particularly promising results. For instance, using semitransparent PV cells can lead to a significant 29% increase in power generation. Transforming traditional PV-based systems into hybrid PV-SCPP configurations can harness the complementary strengths of both technologies, resulting in more reliable, sustainable, and uninterrupted energy production. This review presents a comprehensive and exhaustive study of all these hybrid PV systems, which is a unique contribution not previously addressed in any literature. The study covers their operational principles, methodologies, challenges, numerical approaches, exergy analysis, and economic considerations, providing a comprehensive overview of current advancements and laying the groundwork for future commercialization of integrated systems. The review highlights key developments in methods for enhancing the performance of standalone SCPPs, with a strong emphasis on hybrid PV-SCPP systems aimed at boosting efficiency and output. Furthermore, it suggests several innovative designs for future exploration of these hybrid systems, offering valuable insights for researchers and policymakers to steer further research and development in this area.

作为可持续能源解决方案，太阳能烟囱发电厂（SCPPs）正受到越来越多的关注，但其效率和能量输出仍有局限性。为了提高这些因素，人们正在研究各种混合策略，例如将太阳能光伏电池、废热回收、地热能、生物质能、热存储和热交换器结合在一起。其中，光伏电池与 SCPPs 的结合尤其显示出良好的效果。例如，使用半透明光伏电池可使发电量大幅增加 29%。将传统的光伏系统转变为光伏-SCPP 混合配置，可以利用两种技术的互补优势，实现更可靠、可持续和不间断的能源生产。本综述对所有这些混合光伏系统进行了全面、详尽的研究，这是以前任何文献都未涉及的独特贡献。研究涵盖了它们的运行原理、方法、挑战、数值方法、放能分析和经济考虑因素，全面概述了当前的进展，并为未来集成系统的商业化奠定了基础。该综述重点介绍了提高独立 SCPP 性能的方法的主要发展，特别强调了旨在提高效率和产出的光伏-SCPP 混合系统。此外，它还为这些混合系统的未来探索提出了几项创新设计，为研究人员和政策制定者指导该领域的进一步研究和开发提供了宝贵的见解。

While using metal grid electrodes improves the performance of solar cells, it inevitably leads to frontal shading losses, series resistance losses, and losses due to lateral currents in the top layer. In this study, we analyze the influence of the front electrode grid line size parameters on the efficiency loss of copper indium gallium selenide (CIGS) thin-film solar cells and then use numerical analysis to obtain the optimal parameters for the design of the grid line size, and at the same time, explore the optimal design strategy for the grid line for non-conventional shaped solar cells. The experiments show that the photoelectric conversion efficiencies of the optimized rectangular solar cell samples are increased by 2.19% and 5.44%, respectively, over the two pre-optimized samples. The optimized design parameters can be used to improve the conversion efficiency of solar cell modules in commercial production, and the optimization method, which only modifies the relevant parameters of the grids, does not require the introduction of complex manufacturing methods in production, which can save costs and is easy to be extended to the production of different types of CIGS thin film solar cell modules in order to achieve the goal of improving efficiency.

虽然使用金属栅电极可以提高太阳能电池的性能，但不可避免地会导致正面遮光损失、串联电阻损耗以及顶层横向电流造成的损失。在本研究中，我们分析了正面电极栅线尺寸参数对铜铟镓硒（CIGS）薄膜太阳能电池效率损失的影响，并通过数值分析获得了栅线尺寸设计的最佳参数，同时探索了非常规形状太阳能电池的栅线最佳设计策略。实验表明，优化后的矩形太阳能电池样品的光电转换效率比预先优化的两个样品分别提高了 2.19% 和 5.44%。优化后的设计参数可用于提高商业化生产中太阳能电池组件的转换效率，而且该优化方法只需修改电栅的相关参数，不需要在生产中引入复杂的制造方法，可以节约成本，易于推广到不同类型 CIGS 薄膜太阳能电池组件的生产中，以实现提高效率的目标。

Current ironmaking process leads to large CO₂ emissions due to the use of fossil fuels as both heating agent and reducer. An alternative ironmaking process based on the reduction of iron ore by hydrogen under a concentrated light flux, simulating a direct solar heating reactor, is studied here. Experiments were performed in batch mode on the iron ore pellets used in industry, which consist in spherical agglomerates of iron oxide with a diameter of ca. 2 cm. Quantitative analysis of the reduction yield and kinetics were deduced from the Rietveld refinements of X-ray diffraction patterns as well as optical and scanning electron microscopy. It is shown that hydrogen pressure has a significant influence on the time evolution of the reaction, probably by its influence on re-oxydation. Observations and analysis of cut pellets show that reduction starts from the illuminated surface towards the shadowed side, due to a large temperature gradient inside the sample. This conducted us to perform experiments in which pellets were rotated, which significantly reduce reduction time. On single pellets, a reduction yield of 96 % was reached in 12 min by turning them three times during exposure. Samples under the form of gravels and flat disks were also tested. The former did not lead to significant improvement, but a 96 % reduction yield was measured on 2-mm-thick disks after only 2 min of exposure. An analysis of the energy efficiency of the process is provided. These results show that hydrogen-based solar metallurgy could meet industrial requirements in terms of reduction yields and might be envisaged as a low-carbon ironmaking process.

由于使用化石燃料作为加热剂和还原剂，目前的炼铁工艺导致大量二氧化碳排放。本文研究了一种基于氢气在集中光通量下还原铁矿石的替代炼铁工艺，模拟了太阳能直接加热反应器。实验以批量模式进行，对象是工业中使用的铁矿石球团，由直径约 2 厘米的球形氧化铁团块组成。根据 X 射线衍射图样的里特维尔德细化以及光学和扫描电子显微镜，对还原产量和动力学进行了定量分析。结果表明，氢气压力对反应的时间演化有重大影响，可能是通过其对再氧化的影响。对切割后的颗粒进行的观察和分析表明，由于样品内部存在较大的温度梯度，还原反应是从受光面开始向阴影面进行的。这促使我们进行了颗粒旋转实验，从而大大缩短了还原时间。对于单个颗粒，在照射过程中旋转三次，12 分钟内就能达到 96% 的还原率。我们还测试了砾石和平盘形式的样品。前者的效果并没有明显改善，但在 2 毫米厚的圆盘上，仅经过 2 分钟的曝晒，就测得了 96% 的还原率。此外，还对该工艺的能效进行了分析。这些结果表明，氢基太阳能冶金在还原产量方面可以满足工业要求，并可被视为一种低碳炼铁工艺。

The design method of dual working medium, heat exchanger-evacuated tube assisted drying system is proposed in this work. Operation control method of solar drying system is specified. In order to achieve a drying cabin suitable air temperature controlling method and the expected operating environment of the system, the evacuated tube solar collector with dual-function hybrid drying system is considered as a case. Effect of operating ambient factors on efficiency of solar heating unit (SHU) is evaluated using traditional thermodynamics, as well as five different machine learning (ML) algorithms using Python software. The aim of this is to predict thermal performance of SHU. Influence of ambient temperature, solar intensity, and water flow in SHU on outlet air temperature as well as collecting efficiency are observed. Furthermore, ambient relative humidity is found to be the most important effect parameter for the outlet temperature of solar heating unit. As a result, the randomised lasso algorithm suggests that solar intensity is a crucial parameter. Gradient boosting regression tree (GBRT) can be considered as the good fit prediction performance with MAE of 0.31 and 0.59, RSME of 0.54 and 0.72, and coefficient of determination (R²) of 0.98 and 0.94 on training as well as testing values, correspondingly. This study also pointed out the direction for the application and development of thermodynamics analysis and machine learning.

The utilization of perovskite and electrode materials enables the production of semitransparent solar cells that allow partial transmission of light, making them suitable for integration into windows and other transparent surfaces. However, achieving optimal performance is challenging due to the trade-off between transparency and power conversion efficiency (PCE). This study emphasizes the crucial role played by material selection, active layer thickness, and transparent electrode configuration in determining this trade-off in semitransparent perovskite solar cells (ST-PSCs). Through multi-physics device simulations, we optimize the thickness and compare the performance of two active layer materials − MAPbI₃ and CsPbI₃ − resulting in increased average visible transmission (AVT) as well as PCE. Notably, MAPbI₃ outperforms CsPbI₃ as an absorber material in ST-PSCs. CsPbI₃ achieves an optimal light utilization efficiency (LUE) of 4.06 % at a thickness of 300 nm, while MAPbI₃ reaches 4.15 % at a thickness of 100 nm, which shows better performance. Furthermore, our findings demonstrate that the MoO₃/Ag/WO₃ configuration enhances both PCE and AVT compared to alternative configurations due to MoO₃′s mitigated parasitic behavior. These results provide valuable insights for advancing solar cell technologies applicable to practical uses such as window integration or other transparent surfaces.

利用过氧化物和电极材料可以生产出允许部分透光的半透明太阳能电池，使其适合集成到窗户和其他透明表面中。然而，由于透明度和功率转换效率（PCE）之间的权衡，实现最佳性能具有挑战性。本研究强调了材料选择、活性层厚度和透明电极配置在决定半透明过氧化物太阳能电池（ST-PSCs）性能权衡中的关键作用。通过多物理场器件模拟，我们优化了 MAPbI3 和 CsPbI3 两种活性层材料的厚度，并比较了它们的性能，从而提高了平均可见光透射率（AVT）和 PCE。作为 ST-PSC 的吸收材料，MAPbI3 的性能明显优于 CsPbI3。CsPbI3 在厚度为 300 纳米时的最佳光利用效率（LUE）为 4.06%，而 MAPbI3 在厚度为 100 纳米时的最佳光利用效率（LUE）为 4.15%，表现出更好的性能。此外，我们的研究结果表明，与其他配置相比，MoO3/Ag/WO3 配置可提高 PCE 和 AVT，这是因为 MoO3 可减轻寄生行为。这些结果为太阳能电池技术的发展提供了宝贵的启示，这些技术适用于窗户集成或其他透明表面等实际用途。
