Kesterite thin film solar cell has been fabricated by chemical spray pyrolysis (CSP) of an aqueous solution followed by high temperature selenization. The pyrolysis formation of Cu2ZnSnS4 was conducted in atmospheric condition with substrate temperature of 280 °C. X-ray diffraction and Raman spectro...
