| Commentaire | : | Solar energy is the most important source of renewable and clean energy, and research on solar cells is a prominent topic of interest in the energy profession. Many materials, such as CdTe, CIGS, and CZTS, have been developed to manufacture thin film solar cells. The CIGS (Copper-Indium-Gallium-diSelenide) based solar cell is regarded as one of the most promising thin film solar cells due to its numerous advantages, including higher efficiency at both the module and cell levels, simple manufacturing processes, low production costs, excellent durability and stability, and radiation hardness. For this purpose, our strategy is based on the incorporation of a back surface field (BSF) layer between Mo and CIGS. The BSF material not only solves this issue, but it also improves efficiency. This study offers a new perspective that consists of lowering the raw material needed in the thin film construction by producing the layer in the shape of a line, while also addressing the heating of the solar cell by utilizing a field layer with a distinct back surface. As a consequence, for the first time, a low cost and widely available 0.3m thick back surface field layer is added in the fundamental CIGS solar cell structure of ZnO: Al / ZnO / CdS / CIGS /Mo, resulting in the alternative structure of ZnO:Al/ZnO/CdS/CIGS/BSF/Mo. Using SCAPS-1D, it has been quantitatively investigated the impact of integrating various BSF layers as an interface layer between the Cu(In, Ga)Se 2 (CIGS) absorber layer and the molybdenum (Mo) back contact in a typical CIGS thin film solar cell (a Solar Cell Capacitance Simulator). |
