Modeling of J-V characteristics of CZTS based thin film solar cells including voltage and space dependent electric field in the absorber layer

Abstract

This work proposes an analytical model incorporating the effects of the series resistance to deduce the current-voltage characteristics for ZnO/CZTS based thin film solar cell. The evolving mathematical intractability for the inclusion of the series resistance has been resolved by using the concept of perturbation theory. The various effects utilizing the proposed model has been observed and analyzed. The model may be helpful to gain more physical insight of the CZTS based solar cells.
