Simulation of CBTS Thin-Film Solar Cells: Effect of Surface Defects and Layer Thickness Using SCAPS-1D

Abstract

Using the 1D-SCAPS modeling tool, we assessed the CBTS solar cell and contrasted it with an actual research.  In order to align the program's results with scientific findings, the analysis found that the software simulates reality.  The cell efficiency was 0.26%, and we improved the cell by adjusting the density of surface defects in the CBTS/CdS absorption layer. After installing the optimal surface defects value in the software, we changed the buffer layer (CdS) thickness from.050 nm to.50 nm. The lower the surface defects value, the greater the cell efficiency value (from 0.220% to 0.7). After raising the buffer layer's thickness from 0.7% to 1.04 and figuring out the program's ideal buffer layer thickness, we changed the CBTS absorption layer's thickness from 0.5 nm to 2.5 nm. Increasing the thickness of the absorber layer (from 0.7% to 1.65%) and the absorber layer and buffer CBTS-CdS when the voltage (from 0.3V to 0.7V) and current (from 2.6mA to 7.9mA) increased boosted the cell efficiency.
