Cadmium telluride (CdTe) is currently known to be one of the reliable cost-effective materials for manufacturing solar cells. In this work, different materials such as magnesium fluoride (MgF2), aluminum trioxide (Al2O3), tin oxide (SnO2), and magnesium oxide (MgO) were applied as a single antireflection coating (ARC) layer and characterized their optoelectrical properties of the resulting CdTe solar cells. A personal computer one-dimensional (PC1D) simulation study was carried out to instigate the overall performance when varying the thickness of the absorber and window layers. Simulation results confirmed that Al2O3 single ARC layer with thickness of 83 nm achieved the best efficiency of 17.81% as compared with the other ARC materials. The Al2O3 single ARC layer resulted in a short-circuit current of 2.89 A and open-circuit voltage of 0.740 V.

Investigation on the Effect of Accumulated Charge-Induced Degradation on Multilayer Photovoltaic Insulating Backsheets Based on Atomic Force Microscopy

The impact of doping concentration and thickness of n-InGaN and p-InGaN regions on the power conversion efficiency of single junction-based InGaN solar cells was studied by the Silvaco ATLAS simulation software. The doping concentration 5 × 1019 cm−3 and 1 × 1015 cm−3 were optimized for n-InGaN and p-InGaN regions, respectively. The thickness of 300 nm was optimized for both n-InGaN and p-InGaN regions. The highest efficiency of 22.17% with Jsc = 37.68 mA/cm2, Voc = 0.729 V, and FF = 80.61% was achieved at optimized values of doping concentration and thickness of n-InGaN and p-InGaN regions of InGaN solar cells. The simulation study shows the relevance of the Silvaco ATLAS simulation tool, as well as the optimization of doping concentration and thickness of n- and p-InGaN regions for solar cells, which would make the development of high-performance InGaN solar cells low-cost and efficient.

MgO-Based Heat Dissipation Back Sheet for Photovoltaic Module: Development and Evaluation

The back sheet is one of the most important materials in photovoltaic (PV) modules. It plays an important role in protecting the solar cell from the environment by preventing moisture penetration. In the back sheet, the outermost layer is composed of a polyester (PET) film to protect the PV module from moisture, and the opposite layer is composed of a TiO2 + PE material. Nowadays, PV modules are installed in the desert. Therefore, methods to improve the power generation efficiency of PV modules need to be investigated as the efficiency is affected by temperature resulting from the heat radiation effect. Using a back sheet with a high thermal conductivity, the module output efficiency can be increased as heat is efficiently dissipated. In this study, a thermally conductive film was fabricated by mixing a reference film (TiO2 + PE) and a non-metallic material, MgO, with high thermal conductivity. UV irradiation tests of the film were conducted. The thermally conductive film (TiO2 + PE + MgO) showed higher conductivity than a reference film. No visible cracks and low yellowing degree were found in thermally conductive film, confirming its excellent UV durability characteristics. The sample film was bonded to a PET layer, and a back sheet was fabricated. The yellowing of the back sheet was also analyzed after UV irradiation. In addition, mini modules with four solar cell were fabricated using the developed back sheet, and a comparative outdoor test was conducted. The results showed that power generation improved by 1.38%.

Development of a Solar Cell Back Sheet with Excellent UV Durability and Thermal Conductivity.

The need for innovative design and materials is increasing for various types of photovoltaic (PV) installations in building integrated PV, agricultural, and floating systems. It is crucial to reduce the weight of the PV module to maximize its use in such applications. For this purpose, the front surface must be made of a polymer-based material instead of tempered glass. This study focuses on the analysis of the optical and ultraviolet (UV) reliability properties of various lightweight polymer front sheets. The results show that the transmittance and UV properties of the front material are good. Moreover, a PV module with a polymer front sheet rather than glass was constructed, and a characteristic investigation as well as UV reliability test were performed. The transmittance of the polycarbonate (PC) front sheet decreased by only <3% and the module fabricated with PC exhibited only an approximately 6% power drop after the UV reliability test; hence, the PC is suitable for use in the PV module industry.
