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.
