An indigenously developed chemical spray pyrolysis system was used to deposit polycrystalline CuInS 2 thin films. It was found that smaller spray rate results in films with better crystallinity and lower resistivity. Increase in surface roughness of the films was observed for higher spray rates. Variations in film stoichiometry with composition of spray(More)
