摘要
The formation of the interface between a magnetron sputtered (Zn1-x, Mg-x)O buffer layer and a CuIn(S, Se)(2) absorber in thin film solar cells has been investigated by x-ray photoelectron spectroscopy and x-ray induced Auger electron spectroscopy. Detailed analysis of the spectra shows the incorporation of Zn into the absorber surface in the initial stage of the deposition process forming ZnS and/or ZnSe bonds. As a result we find the buffer layer to be Zn-depleted near the interface. (C) 2009 American Institute of Physics. [doi:10.1063/1.3230071]
