Preparation And Photovoltaic Properties Of Tin Sulfide And Tin Oxysulfide Thin Films By Spray Pyrolysis Technique

Abstract
Tin sulfide and a related novel compound, tin oxysulfide, thin films were deposited from the aqueous solution containing tin (11) chloride and thiourea by a spray pyrolysis technique. The constituent atoms of the thin films have merits of nontoxicity and availability. Physical and photovoltaic properties of both films were also investigated. It has, therefore, been considered that these two compounds become a promising absorbing layer for solar cell on account photovoltaic ability with high absorption coefficient and appropriate bandgap energy.
