Investigation for Optimal Structure of CdS/SnS Solar Cell from Numerical Analysis

In this paper the absorber layer of Tin mono-sulfide(SnS) thin film had been explored as an absorber layer of solar cell using the one dimensional simulator AMPS-1D.(Analysis of Microelectronic and Photonic Structures). The studies conducted by emphasize given to the SnS absorber layer thickness effect of the operating temperature and sun intensity with cell structure “ITO/ZnO/CdS/SnS/Ag”. The thickness of SnS thin film has been changed from 1000nm to 2000nm. The best efficiency of 13.2% is obtained at the highest thickness 2000nm at operating temperature is 3500C under 1sun. The study highlights the effect of thickness on the SnS absorber layer thin film solar cell.
