| dc.description.abstract | This study focuses on enhancing the performance of Concentrated Solar Photovoltaic (CSPV) modules using improved oxide layers and a GaSb substrate infused with bismuth-arsenic (Bi-As) compounds. Two designs were analyzed: one using pure ZnO as the window layer, and the other using Co-doped ZnO (Zn₀.₉₄Co₀.₀₆O). Both configurations incorporated GaSbBi and GaAsSbBi layers, doped with 3% and 6% bismuth, respectively. The results demonstrated a clear efficiency boost with Zn₀.₉₄Co₀.₀₆O, regardless of GaAsSbBi layer thickness. The ZnO-based module achieved 13.55% conversion efficiency, while the Co-doped variant reached 15.89%, with only a slight drop in fill factor. This performance enhancement confirms the effectiveness of Co-doped ZnO as an advanced window layer, promoting higher light absorption and energy conversion. These findings offer a promising direction for CSPV module optimization, paving the way for more efficient and sustainable solar technologies. | |
