Numerical Simulation for Enhancement of output Performance of WS2 based Thin Film Solar Cells

Abstract

In this paper , Tungsten Disulfide is utilized for the development of an efficient model, using SCAPS one dimensional Simulator. Performance of the developed model is compared with other thin film solar cells currently under study. An efficient solar cell model with comparable photovoltaic parameters to the recent thin film models is obtained. Taking ZnO window layer material, ZnSe as buffer layer material, WS2 as absorption layer material and Mg as back surface field with back reflector a 20% efficient, design with 0.9Voc, 25 mA/cm2 current density and fill factor of 85% is developed.
