摘要：
Cu(In,Ga)Se-2 thin films have been prepared by selenization of the evaporated metallic precursors on transparent and conductive ITO-coated as well as uncoated glass substrates, by starting from slightly Cu-rich or Cu-poor overall metallic proportions. The objective is to determine the influence of the Cu availability on the constituents distribution achieved after selenization, by means of data obtained at several film depths by grazing incidence X-ray diffraction and X-ray photoelectron spectroscopy that have been related to the overall optical and structural characteristics of the material. This study points out the possibility of achieving homogeneous or graded absorber layers, showing for homogeneous samples an ITO/Cu(In,Ga)Se-2 interface with ohmic electrical characteristics suitable to act as back contact for semitransparent photovoltaic devices.
