Deposition And Characterization Of CuInS2 thin films Deposited Over Copper thin films.

Simple, cost effective and versatile spray pyrolysis method is effectively combined with vacuum evaporation for the deposition of CuIns₂ thin films for photovoltaic applications. In the present study In₂s₃ was spray deposited over vacuum evaporated Cu thin films and Cu was allowed to diffuse in to the In₂S₃ layer to form CuInS₂. To analyse the dependence of precursor volume on the formation of CuInS₂ films structural, electrical and morphological analzes are carried out. Successful deposition of CuInS₂thin films with good crystallinity and morphology with considerably low resistivity is reported in this paper. [ABSTRACT FROM AUTHOR]
