Cu2S-Cd1-YZnYS solar cells: Influence of zinc sulfide composition on photovoltaic efficiency
Written by sctunisie no commentsWe have realized Cu,S-Cd1-YZnYS photocells (0 ≤ Y ≤ 0,35), starting from CdS, Al2O3-CD1-YZnYS prepared from "low pressure" spray pyrolysis on heated glass substrates. The Cu2S film is formed by ion exchange reaction from the alloy films (CdZn)S in aqueous solution of Cu(1) at 90°C. The zinc concentration of the layers Cd1-YZnYS is always higher than the solution one. The conversion efficiency reaches 4.4 %, for a concentration of ZnS equal to 0.12.
