Numerical Analysis of Cadmium Telluride Solar Cell

Abstract

CdTe solar cell is very popular photovoltaic because of lower cost and higher stability. The main issue is to create stable ohmic contact between CdTe base layer and back contact. Only technique used to solve this is to insert BSF layer between absorber layer and back contact. This paper highlights the analysis of reference and proposed cell. From simulation it can be seen that by inserting BSF layer cell efficiency can be improved with optimum thickness of CdTe layer. The reference cell shows the efficiency 19.68 %( Voc=0.7838, Jsc =29.845294, FF =84.14).After inserting back surface field layer and with minimum thickness of absorber layer cell efficiency is increased up to 22.92% (Voc= 2.6232, Jsc =30.770710, FF =28.39).
