Contribution of Carrier Quantization Effect towards Performance of Nanostructured CFTS/CFTSe Solar Cells

Abstract

In this work, a detailed analysis is carried out to evaluate the performance enhancement of CFTS solar cell with the inclusion of nano-structures. Multiple quantum well (QW) with CFTSe/CFTS as well constituents are embedded into the cell structure to maximize the power conversion efficiency. Numerical modeling of the cell structure is carried out with optimized parameters and analyzed. The performance of the CFTS solar cell is carried out with a variation in the number of QWs such as 2 and 10 QWs in a comparative manner with no QWs. Results indicate an escalation in device efficiency when the number of QWs are increased. A phenomenal efficiency of 18% is achieved with a fillfactor of 71% and 82% quantum efficiency from a 10 QW embedded structure.
