Electrodeposition of Pyrite Thin Films for Solar Cell
Electrodeposition of Pyrite Thin Films for Solar Cell
摘要
Abstract
Formation of pyrite (FeS2) films through electrodeposition from aqueous solutions which contain different source materials has been investigated. Na2S2O3·5H2O is used as sulfur source material, FeSO4·7H2O, FeCl2·4H2O and FeCl3·6H2O are used as iron source materials respectively. The samples are annealed in N2atmosphere at 400℃and 500℃respectively. From XRD (X-ray diffraction) patterns of the films, it is found that there are peaks of FeS2, FeS and Fe7S8in all films, but there are sharp and more peaks characterizing FeS2in the film from Na2S2O3+FeSO4than other films, and 400℃is the more suitable temperature than 500℃for annealing the samples in N2atmosphere. In addition, one solution can be used repeatedly.
