Impact of Performance Parameters on the Efficiency of Cu2SnS3 (CTS)/Si Tandem Solar Cell by SCAPS-1D

In this paper, photovoltaic characteristics of tandem or multi-junction solar cell structure based on Cu2SnS3 (CTS) were analyzed. Solar Cell Capacitance Simulator software (SCAPS-1D) was used to examine an optimistic material for solar cell applications. To investigate the efficiency and stability of the tandem Cu2SnS3 (CTS) solar cell (p-CTS/p-Si/n-Si) structure, silicon (Si) was employed as the multi-junction. The effect of changing simulation parameters including carrier concentration, layer thickness, and ambient operating temperature on this redesigned structure, which consists of heavily doped p-CTS and Si layers, was examined. Enhancing the layer thickness of p-CTS, n-Si, p-Si, and the carrier concentration of p-CTS resulted in increased photovoltaic effects.
