Abstract
A method of forming an compound semiconductor thin film of chalcopyrite structure includes the steps of heating up elemental VI powder in a first chamber to produce VI vapor flux. The VI vapor flow is introduced into a second chamber and an Argon plasma is utilized to crack large molecular VI fractions to generate small VI species. The small molecule VI species are homogeneously deposited on the metallic I-III precursor layers and the precursor film is sealed into a graphite box and transferred to an annealing chamber to create an absorber layer with a large grain size and good crystalline structure.
