Improvements in the quality of CuSbS/sub 2/ films used in solid state solar cells

Abstract

The aim of the paper is to present the research made in order to improve the diode behaviour of CuSbS/sub 2/ absorber films used in solar cells. Films obtained with other solvent than water (ethanol) were tested. This films reveal a small improvement in the quality of the films but after the optimization of the ethanol amount that must be added the improvements can be more consistent. Sb-rich films were obtained, free of pinholes but the I-V measurement under illumination reveals a very small injection of electrons from the absorber into the n-type semiconductor.
