Optical characterization of Cu2ZnSnS4 thin films prepared by non-vacuum process for photodetector application

Abstract

Cu2ZnSnS4 (CZTS) thin films have been successfully deposited by non-vacuum, sol-gel process on Molybdenum (Mo) coated Soda Lime Glass (SLG) substrate. The Cu, Zn, and Sn liquid precursor ratios have been pre-determined so as to achieve a Cu poor (23%) and Zn (14%) rich film with a goal to optimize absorber performance. A thermal annealing step (500°C, 60min… (More)
