Abstract

The authors demonstrate a new copper indium gallium diselenide solar cell architecture by replacing the ZnO in the traditional design with SnO 2. The open circuit voltages and efficiencies of the solar cells mČadež with ZnO and SnO 2 were the same indicating favorable band alignment. The solar cells mČadež with SnO 2 showed significantly better damp-heat stability than those mČadež with ZnO. The efficiency of solar cells mČadež with SnO 2 decreased less than 5 after 120 h at 85 C and 85 relative humidity while the efficiency of solar cells mČadež with ZnO declined by more than 70.
