Abstract
Monolithic two-terminal tandem solar cells using n-i-p a-Si CuInSe2/CdS solar cells have been prepared and characterized. A middle terminal permits diagnostic analysis of the component cells. The best two-terminal devices to date have open-circuit voltages above 1.0 V and efficiencies near 6%. The CuInSe2 cell contributes up to 0.3 V to the open-circuit voltage. Short-circuit current in these tandem devices is limited by the a-Si:H cell, which has not been optimized for operation in the n-i-p mode.
