Cubic Silicon Carbide (3C-SiC) can be a potential photovoltaic material for thin-film solar cells because of its wide bandgap and non-toxic nature. In this work, we present 3C-SiC as an alternative to the conventional CdS buffer layer and investigate the performance of the proposed 3C-SiC/CIGS cell ...

Abstract This study models and optimizes the CsGeI 3 -based perovskite solar cell with an n-i-p for practical fabrication. This simulation determined that power conversion efficiency (PCE) has practically saturated over 700 nm of thickness, and the increase rate is barely 0.15 percent up to 1100 nm....
