A non-hydrazine solution process has been considered as a promising way for the deposition of Cu(In,Ga)(S,Se)2(CIGSSe) thin films. However, from our previous work, the presence of a fine-grained layer in the absorber layer was shown to be an obstacle to further improve the solar cell efficiency. Here, an improved fabrication route is proposed to solve this problem. A mixture of Cu2S, In2Se3, Ga and Se was simultaneously dissolved in 1,2-ethanedithiol and 1,2-ethylenediamine, forming a… CONTINUE READING
