CHALCOPYRITE THIN-FILM SOLAR CELL COMPRISING CDS/(ZN(S,O) BUFFER LAYER AND ASSOCIATED METHOD OF PRODUCTION

摘要

The invention relates to a chalcopyrite thin-film solar cell comprising a CIS absorber layer (14), a buffer layer (16) directly applied onto the CIS absorber layer and a ZnO-containing window layer (18, 20) directly applied onto the buffer layer. The solar cell is characterized in that the buffer layer consists of CdS and Zn(S,O), a concentration of CdS decreasing towards the ZnO-containing window layer, starting from the CIS absorber layer.
