<div><div>Global freshwater scarcity is a critical challenge, particularly severe in remote Australian communities where seawater intrusion and aquifer salinisation exacerbate the need for alternative water resources.

Background
Currently, the heating measures for rural households face significant disadvantages such as reliance on fossil fuels, poor thermal comfort, and high carbon emissions.
Objectives
This study designed a solar-coupled domestic biomass boiler parallel heating system (SBPHS) with collaborative optimization.
Methods
The SBPHS was developed based on a typical rural residence in cold regions. Subsequently, a parametric analysis was performed on both component configuration and operating parameters. Furthermore, we determined optimal configurations of the SBPHS using the life cycle cost (LCC) as the optimization objective. Solar fraction, total power consumption, effective heat collection and boiler runtime were used as performance indicators to evaluate the system.
Results
Simulation results were in good agreement with measured data. Parametric analyses indicated that component design should consider energy performance and economics, especially in rural areas. As a start/stop signal for the collector system, the collector-tank temperature difference significantly affected effective heat collection and system energy consumption. Further, flow rates had significant impacts on all performance indicators, especially collector flow rate. Considering the optimum operating conditions throughout the system’s life cycle, Hooke-Jeeves algorithm was adopted to optimize component configurations and operating parameters simultaneously. Post-optimization, LCC of the SBPHS was reduced by 12.3 %. The optimized system could achieve a solar energy share of up to 62.7 %, total energy consumption reduction of 13.6 %, and biomass fuel consumption reduction of 26.3 %, indicating significant energy savings.
Conclusion
These findings enhance the feasibility of implementing the SBPHS in rural residences in cold areas and provide theoretical foundation for the design and operation of system.

Perovskite materials are revolutionizing the solar cell (SC) industry, continually enhancing their properties and establishing a prominent photovoltaic technology. Among these, BaSnS3 (BTS) and AgTaS3 (ATS) stand out for their strong potential as absorber layers. These inorganic chalcogenide perovskites address the drawbacks of their organic counterparts, being both lead-free and non-toxic, thereby making them highly suitable for photovoltaic (PV) applications. The exploration of BTS and ATS as absorber layers in a tandem solar cell’s top and bottom cells has yielded remarkable outcomes. The innovative tandem solar cell design features a top cell structured as n-WS2/p-BaSnS3/p+-MoS2 and a bottom cell configured as n-WS2/p-AgTaS3/p+-GeS. This theoretical study using SCAPS-1D demonstrates a high efficiency of 42.57 % with a VOC of 2.03 V, a JSC of 23.29 mA/cm2, and an FF of 89.85 %. These impressive results are achieved with adjusted layer thickness, carrier doping and defect levels, highlighting the strong potential of BaSnS3 and AgTaS3 photoactive materials. The findings reveal the viability of innovative, all-inorganic perovskite-based tandem solar cells, offering a promising avenue for future sustainable and high-efficiency photovoltaic device technologies.

Due to their potential to be an absorber layer in perovskite solar cells with cheap cost, outstanding stability, and high efficiency, lead-free double perovskite Cs2AgBiI6 and Cs2AgBiBr6 have attracted tremendous attention recently. In this work, Cs2AgBiI6 and Cs2AgBiBr6 are introduced to create a perovskite-perovskite bilayer solar cell FTO/ETL/Cs2AgBiI6/Cs2AgBiBr6/HTL/Au through SCAPS-1D. The Cs2AgBiI6/Cs2AgBiBr6 double absorber layer structure significantly reduces lead toxicity while improving the device’s stability and light absorption capabilities, according to the results. We chose the optimal hole transport layer (HTL) and electron transport layer (ETL) to examine the impacts of several HTLs and ETLs on the PSC. The device’s performance appears to be significantly impacted by the energy level alignment of the absorber and transport layers, and that ideal energy band structure facilitates the carriers’ transportation and separation. Through numerical simulations, the impacts of some factors containing the absorber layer thickness, defect density and doping concentration of the perovskite layers, operating temperature, and different back-contact electrodes, were examined. The optimized results are PCE = 34.36 %, FF = 93.35 %, Jsc = 24.78 mA/cm2, and Voc = 1.48 V. This work demonstrates that double perovskite Cs2AgBiI6 and Cs2AgBiBr6 hold great potential for application in photovoltaic and optoelectronic devices.

The increasing competition of land for various purposes has led to the consideration of using it effectively while catering to energy and food security. This study investigates the integration of photovoltaics (PV) systems with farmlands that cultivate potatoes in the UK, analysing energy production and crop yields across eleven regions. Using PVsyst for solar simulations and DSSAT for crop modelling for various PV setups including both monofacial and bifacial systems in both fixed and tracking configurations were examined. This work revealed significant regional disparities in solar irradiance, temperature, and precipitation, impacting both electricity and agricultural output. This study indicates that tracking bifacial 440Wp systems (TB) generated an average of 24.6% more energy than static bifacial (SB) systems with the highest difference of 26.37% in Brighton but at the cost of reduced crop yields. The land equivalent ratio (LER) varies, with SB systems generally achieving higher values with the highest obtained value of 1.39 reflecting their balance between energy and crop production. Financial analysis demonstrates that same area tracking monofacial (SATM) configurations offer the highest internal rate of return (IRR) though there is a huge variation in the outcomes when comparing the lowest and highest there is a difference of 41.16%. The levelized cost of electricity (LCOE) was the lowest, with regions receiving more irradiance (Brighton) indicating the increased economic feasibility for the proposed system. This evaluation emphasizes the potential of agrivoltaics to optimise land use for dual purposes, promoting sustainable energy and food production while highlighting the importance of considering local climatic conditions and system design to utilise the benefits of agrivoltaics.

Severe carrier recombination at the back (Mo/CZTSSe) and front (CZTSSe/CdS) interfaces is one of the most important reasons hindering the development of open-circuit voltage (VOC) and fill factor (FF) in Cu2ZnSn(S, Se)4 (CZTSSe) solar cells. In this study, we intentionally introduced a non-uniform distribution of Cd impurities into the middle of the absorber layer, designing and fabricating a CZTSSe solar cell with a non-uniform “V”-shaped graded bandgap structure. This structure is aimed at providing a favorable back electric field, reducing carrier recombination at the Mo/CZTSSe interface. The PCE of the CZTSSe solar cell improved from 8.88 % to 10.89 %, significantly enhancing FF and VOC. Additionally, we utilized the solar cell simulation software SCAPS-1D to simulate the position of the minimum point in the V-shaped graded bandgap and combined this with experimental results to explore the effect of Cd doping location on the performance of CZTSSe solar cells. It’s worth noting that the non-uniform Cd-doped solar cell displayed exceptional stability, demonstrating an efficiency enhancement from 10.28 % to 10.94 % after being exposed to air for 30 days.

Nevertheless, it is difficult to achieve simultaneously high absorption, insensitivity with a large angle of incidence, polarization independence and, highly efficient photothermal conversion over a wide range of wavelengths for existing solar energy absorbers. Herein, an ultra-wideband and high-performance solar perfect absorber for the spectral range of 200–5000 nm has been proposed. It consists of a Ti metal substrate, a Ti-Al2O3 pattern layer with etched square annular air cavity, and a Si3N4 dielectric layer surrounding the bottom of the pattern layer. Over the spectral range spanning from 200 to 5000 nm, the average absorbance is 97.7 %, and the minimum absorbance is above 91 %. In solar energy system, its total photothermal conversion efficiency is 90.9 % at 1000 K, with as much as 96.41 % of sunlight absorbed. The interactions between surface plasmon resonance (SPR), guided mode resonance (GMR), magnetic resonance (MR), and cavity resonance (CR) are responsible for excellent performance of the ultra-broadband absorber. Additionally, the absorber is not sensitive to wide angles of incidence and is polarization independent. More interestingly, large angle incidence at TE and TM polarizations has equally excellent performance. Besides, the absorber meets a certain tolerance for geometric manufacturing errors, allowing for low-cost practical manufacturing. The designed absorber is expected to be applied to solar cells and thermo-photovoltaic devices.

In this study, we simulated a non-toxic, all-inorganic CsSnBr3 perovskite solar cell (PSC). Using first-principles PBE functional analysis, we evaluated the optoelectronic characteristics of the CsSnBr3 and performed numerical simulations and optimizations with SCAPS-1D. Our findings indicate that CsSnBr3, possessing a direct band gap of 1.78 eV, represents an optimal inorganic perovskite material for PSCs. The micro-band offset (MBO) energy structure of ZnOS/CsSnBr3/CuI, characterized by a small energy band offset, generates an intrinsic electric field (Ebi) that greatly improves carrier transport and facilitates the separation of photogenerated electron-hole pairs, resulting in a peak power conversion efficiency (PCE) of 18.89 %. Optimization of this structure involved adjusting the doping concentrations in the electron transport layer (ETL) and hole transport layer (HTL) to 1017 cm−3 for the ETL and 1019 cm−3, respectively. Increasing the absorber layer thickness improved photovoltaic characteristics, although high defect densities negatively impacted carrier diffusion length and PSC performance. Additionally, we examined the effect of varying metal back electrode (BME) and the thermal stability analysis on the PV performance of the device The micro-band offset (MBO) energy structure, as revealed by our analysis of the carrier transport pathway, enhances energy level transitions and facilitates more efficient carrier transport. Under optimal conditions, the PSCs with the MBO-energy structure demonstrated exceptional performance, with PCE = 23.98 %, Voc = 1.40 V, Jsc = 19.68 mA/cm2, and FF = 86.74 %. These results highlight the significant potential of the MBO-energy structure for Sn-based PSCs. They offer valuable insights for developing stable, highly efficient, cost-effective, and environmentally friendly CsSnBr3-based PSCs.
