Electrical, photoelectrical and degradation properties of thin film Cu
2S-CdS and Cu2S-Cd1-xZnxS solar cells on the basis of CdS and Cd1-xZnx
S (x = 0.15) film prepared by spray pyrolysis and evaporation in quasi
closed volume were investigated. It was shown that the thin film solar
cells produced by evapolation are high efficient (eta = 7%) and stabl
e.
