Bifacial perovskite/silicon solar cells can combine the advantages of tandem technology (high efficiencies) and bifacial modules (additional received irradiance from the rear) to increase the energy yield of photovoltaic (PV) systems further. In literature, it has already been shown that for two-terminal tandems this would require a lower bandgap energy (

E_{g}

) for the perovskite cell, as the rear irradiance increases the current in the bottom cell creating a current mismatch, if this is not considered during optimization. This work expands on bifacial two-terminal tandem optimization by considering aspects not included before. Besides the

E_{g}

, the thickness (

d

) of the perovskite is also optimized, as this also affects the current matching. Additionally, this work studies the trends in different energy losses of the PV module to better understand what affects the optimal perovskite cell. Our simulations show that the optimal

E_{g}

is 1.61–1.65 eV and the optimal

d

is 650–750 nm, which agrees with the observations in literature. The optimal

E_{g}

and

d

are mostly a trade-off between mismatch and thermalization losses, meaning that the mismatch losses should not be fully minimized. Additionally, the irradiance from the rear side is converted less efficiently than the front side irradiance due to larger thermalization and reflection losses. Therefore, the energy yield of bifacial tandem modules, compared to monofacial tandem ones, only increases for large ground albedo. Finally, our results show that the bifacial tandems have over a 25% gain in energy yield compared to bifacial single junction modules and up to 5% gain compared to monofacial tandem modules.

Smart windows with controllable visible transmittance and high near-infrared (NIR) shielding properties have heightened demands for applications in buildings. Herein, we present a hybrid composite film that can control the visible transmittance and shield NIR light via incorporating Cs_xWO₃/SiO₂-SH nanoparticles into normal polymer-dispersed liquid crystals (PDLCs) film. The surface-modified SiO₂-SH helps not only to prevent the aggregation of Cs_xWO₃ nanoparticles in polar solvent, but also to maintain the well-dispersibility of Cs_xWO₃/SiO₂-SH nanoparticles in the prepared film. The results indicated that the samples doped with Cs_xWO₃/SiO₂-SH nanoparticles exhibited more dramatic electro-optical performance regulation effect than the samples doped with Cs_xWO₃ nanoparticles due to the synergistic effect of the enlarged void and the woken anchoring forces. The optical transmittance suggested that the sample containing 7 wt% Cs_xWO₃/SiO₂-SH nanoparticles can control the transmittance between 0.5 % and 71.2 % in the visible light, and shield more than 75 % NIR radiation. In the outdoor experiment, the temperature difference between two model houses consistently around 7 °C after 2 min exposure to the sun under the experimental conditions, suggesting the outstanding thermal management ability of the as-made film. The work could open new doors for the development of energy-saving smart windows in architecture and vehicle glass.

With the rapid development of renewable energy sources, energy storage technology based on solid-liquid phase change materials (SL-PCM) has received widespread attention due to its high-energy density, low cost and environmental friendliness. In this study, a simple synthesis procedure of dendritic silica microspheres (DMNSiO₂) was proposed by adopting a novel multiblock polyurethane surfactant as templating agent, and DMNSiO₂/PEG shape-stabilized phase change materials were prepared through vacuum impregnation using DMNSiO₂ as the mesoporous matrix. The DMNSiO₂ exhibited an inter-connective and uniformly distributed pore structure, which not only encapsulated and shaped the PEG material in a homogeneous manner, but also provided well-defined heat transfer channels. The optimal DMNSiO₂ for supporting PEG had a specific surface area of 876.4 m² g⁻¹, an average pore size of 8.39 nm and a maximum pore volume of 1.33 cm³ g⁻¹. DMNSiO₂/PEG-4 exhibited an excellent phase-change performance with superior phase change enthalpy of 151.54 J/g, which remained almost constant in the thermal cycling experiments with500 times of DSC scanning, The maximum encapsulation rate of DMNSiO₂/PEG is close to 75 %, and the thermal conductivity of DMNSiO₂/PEG composites were all improved comparing to pure PEG (28–57 %), which demonstrate their excellent thermal storage capability and good heat conduction properties. It has a broad application prospect in heat preservation building materials, solar energy storage, battery, and other thermal management fields.

As a next-generation solar cell, perovskite solar cells (PSCs) are attracting increasing research interests for space applications, which necessitates a broad understanding of proton radiation effects in PSCs to predict their performance in space environment. This study provides a comprehensive analysis of the performance degradation in CsMAFAPbI₃-based PSCs induced individually by proton irradiations with different energies: 50 keV, 100 keV, 150 keV, and 200 keV. It is shown that the PSCs start to degrade when the proton fluence exceeds 1 × 10¹³ p/cm² and they are completely destroyed at 3 × 10¹⁴ p/cm². A sigmoidal equation is proposed to describe the photoelectric parameter variation of the PSCs as a function of proton fluence. With increasing proton energy, the damage efficiency of incident protons in PSCs decreases, though 50 keV protons don't follow this trend due to their reduced ion range. While the perovskite absorber in the PSCs exhibits superior radiation resistance, irradiation-induced decomposition of the spiro-OMeTAD hole transport layer is observed due to electronic energy deposition, which accounts for the degradation of device performance.

The analyses of surface morphology and microstructural properties of CdTe thin film absorber layers, deposited by metal organic chemical vapour deposition (MOCVD) on CdS/CdZnS/FTO-coated glass substrates as a function of different growth conditions (non–saturated or Cd–saturated growth condition and post–growth CdCl₂ heat treatment) are presented. Scanning electron microscopy (SEM) images showed that the CdTe absorber surface morphology was relatively smoother with Cd-saturated growth compared to non-saturated conditions, while using a similar II/VI precursor partial pressure ratio. Microstructural characterisation using electron back scatter diffraction (EBSD) measurements indicate a strong influence of the II/VI ratios on the crystalline structure and degree of recrystallisation in Cd–saturated deposited CdTe absorber layers. CdTe absorber layers from a low II/VI ratio of 2 showed a strong Te(A1) Raman spectra band, characteristic of a Te rich composition, whilst a Cd–saturated composition was confirmed in the case of II/VI ratio of 4, as Te(A1) band was significantly suppressed. Cd–saturated grown CdTe:As (II/VI = 4), combined with a CdCl₂ activation process at 440 °C, yielded optimum, highly randomized textured absorber with large grains. Reduced [111] oriented grains and suppression of Te(A1) mode was found to lead to higher V_OC in devices. A high efficiency CdTe:As solar cell with a high V_OC of 825 mV was measured based on the optimum growth condition for the absorber layers.

Electroplating electrodes, a significant technique in the metallization of Tunnel Oxide Passivated Contact (TOPCon) solar cell, have gradually become a research issue. Although laser ablation effectively removed the insulating passivation layer for subsequent metal ion deposition, laser ablation treatment inevitably caused laser-damage to the cell surface. For N-type TOPCon solar cells, laser-damage on the front surface directly impacts the P⁺ emitter layer, significantly affecting the power conversion efficiency of the solar cells. Therefore, this study focused on novel laser repair methods to facilitate electroplated metallization, thereby enhancing the power conversion efficiency of the TOPCon solar cells. Initially, the Raman spectrum method was introduced to calculate the crystallinity of the laser ablation area and evaluate the damage to the cell surface caused by laser slotting. Subsequently, a high-temperature annealing treatment was carried out, and the optimum temperature for the annealing repair method was determined based on implied open circuit voltage (iV_oc) detection. The high-temperature annealing process was improved to assist electroplating metallization for repairing laser-damage. Also, XRD detection was introduced to clarify that the repair effect of laser-damage was limited by the generated SiAlON complex. Additionally, a pre-cleaning of HF solution before electroplating was performed to remove oxidation defects. Compared to TOPCon solar cells without laser-damage repair, the power conversion efficiency of N-type TOPCon solar cells treated with electroplating technique increased to 24.85 %, with an increase of 1.44%_abs.

The current investigation focuses on the computational analysis of the absorber layer Cs₂PtI₆, which is devoid of lead and possesses a low band gap of 1.37 eV. This material is attractive due to its large absorbance coefficient and non-toxic properties. Moreover, one of the most effective methods for enhancing the photovoltaic electrical properties and maximizing its outputs is the selection of more stable and superior charge transfer materials. The materials, MoS₂ and WS₂ were chosen as the most suitable substances for the Hole Transport Layer Material (HTLM) and Electron Transport Layer Material (ETLM) in the device. This work investigates the impact of several factors on the enhancement of a photovoltaic cell using SCAPS-1D computational software. Specifically, the research focuses on the width of the light active film, the concentration of Cs₂PtI₆ defect traps, the concentration of interface defect traps, the acceptor concentration (C_A), influence of back contact, influence of temperature, series resistance (R_s), and shunt resistance (R_sh) and impedance spectroscopy of the Cs₂PtI₆ PSSC. At a temperature of 300 K, the novel configuration FTO/WS₂/Cs₂PtI₆/MoS₂/Pt attains a power conversion efficiency (PCE) of 36.60 %, an open circuit voltage (V_oc) of 1.377 V, a short circuit current density (J_sc) of 30.176 mA/cm², and a fill factor (FF) of 88.03 %, respectively. The summary of results presented here are anticipated to provide assistance and encourage researchers to manufacture this enduring lead-free perovskite solar cell promptly.

Novel carbon materials are proposed and used as additives to improve the solar energy harvesting ability of phase change materials. In this work, waste asphalt is carbonized and utilized as carbon additive to enhance the thermal performance of polyethylene glycol-stearic acid mixture. The improvement of thermal conductivity and thermal energy storage performance by carbonized asphalt is investigated. The results reveal that compared with polyethylene glycol-stearic acid mixture, the maximum increase of thermal conductivity of the composite phase change material is up to 10.2 %, meanwhile the maximum decrease of latent heat of melting and crystallization is 10.9 % and 9.6 %, respectively. During the heating and cooling processes, the total time for the temperature at the geometric center of composite phase change material samples to reach 80 °C can be 68.35 % and 21.71 % shorter than that of polyethylene glycol-stearic acid mixture, respectively. The photothermal conversion performance of the composites can be up to 2.01 times better than that of the polyethylene glycol-stearic acid mixture. The results denote that carbonized asphalt is beneficial for improving the thermal energy storage and photothermal conversion performance of the composites. The use of carbonized asphalt in phase change energy storage proposes a novel method for recycling waste asphalt. The judicious utilization of carbonized asphalt as carbon-based additives in composite phase change material not only diminishes the disposal costs but also enhances the value of the waste, contributing to considerable economic and environmental benefits.

Interfacial evaporation is one of the most environmentally friendly ways to obtain clean water. However, organic pollutants, especially volatile organic compounds (VOCs), can enter the vapor with solar drive and ultimately remain in the condensed water, significantly affecting the widespread application of solar-driven interfacial evaporation. In this study, a 3D interfacial evaporator, designed based on laser induced porous graphene and photocatalysts, has been developed to achieve high evaporation rates and excellent organic compound decomposition simultaneously, thereby obtaining clean water resources. The nano photocatalysts are introduced into porous graphene through hydrothermal and laser induced transfer technology. Due to the excellent photothermal performance of laser induced graphene and the 3D design of device, the solar driven evaporation efficiency of the interfacial evaporator can reach to 2.13 kg m⁻² h⁻¹ under 1.0 solar illumination. Moreover, thanks to the outstanding degradation performance of nano-TiO₂, the device can decompose more than 97 % of organic pollutants (Rhodamine B and Methylene Blue) under 90 min of 1 solar illumination. Furthermore, the decomposition efficiency can reach 99.8 % under 6 h of real solar radiation. Therefore, this device can sustainably provide clean water resources in an environmentally friendly manner, especially designed for economically challenged.

Polycrystalline silicon (poly-Si) carrier-selective passivating contacts (CSPCs), featuring high photoconversion efficiency (PCE) and cost-effectiveness, have emerged as a promising approach for high-efficiency crystalline silicon (c-Si) solar cells. To minimize parasitic absorption losses induced by doped poly-Si window layers, wide bandgap oxygen-alloyed poly-Si (poly-SiO_x) layers are developed. However, challenges persist in achieving excellent surface passivation for boron-doped poly-SiO_x contact stacks, likely caused by boron diffusion during annealing and the reduced doping concentration resulting from lower crystallinity as oxygen content increases. In this study, we investigate the impact on the passivating contact structure and solar cell performance of a 10-nm thick intrinsic hydrogenated amorphous silicon buffer layer with varying oxygen content (a-Si (O_x):H) deposited by plasma-enhanced chemical vapor deposition (PECVD), and placed between the tunneling silicon oxide (SiO_x) and the poly-SiO_x (p⁺). After the hydrogenation step, we obtain both high passivation quality with implied open circuit voltage (iV_oc) of 728.3 mV and low contact resistivity (ρ_c) of 59.18 mΩ cm² on polished surface for oxygen-free a-Si:H buffer layer. These improvements can be attributed to the appropriate thickness of the tunnel oxide and confirmed by transmission electron microscopy (TEM) images, to higher crystallinity of the buffer layer, which facilitates more efficient doping in the buffer layer. This is evidenced by energy dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS) results. At the device level, a front-side textured, rear-side flat, rear junction poly-SiO_x/poly-SiO_x solar cell on n-type c-Si wafer, an efficiency improvement can be observed from 3.55 % without a PECVD buffer layer to 18.9 % with an oxygen-free a-Si:H PECVD buffer layer. The impact of the buffer layer crystallinity on cell performance is further demonstrated by deploying a 10-nm thick LPCVD buffer layer, which facilitates an efficiency of 21.15 % for the same device structure.
