Abstract
A simple and eco-friendly method for solution processing of Cu2SnS3 p-type semiconductor absorbers using a water-based precursor solution is presented. Cu2SnS3 layers were processed by chemical spray pyrolysis deposition of the precursor solution onto Mo-coated glass substrates at 350 °C. The as-prepared layers were placed inside a graphite susceptor with S and SnS powders and were annealed in a tube furnace at 550 °C. The impact of the annealing step on structural, morphological and device characteristics of the prepared layers was studied.
