Stable high-efficiency CuInSe/sub 2/-based polycrystalline thin-film tandem solar cells. Semiannual report, March 16-September 15, 1984
Further improvements have been made in the efficiency of the CuInSe/sub 2//CdS cell with values exceeding 9.5%. Some progress has been made in improving the efficiency of the CdTe/CdS cell but until the quality of the back ohmic contact is improved, substantial progress is not possible. A range of experiments have been carried out and are continuing in order to improve the contact behavior and the resulting reproducibility of high efficiency CdTe/CdS solar cells. Completed tandem cells have been etched back to the CuInSe/sub 2//CdS junction. It was demonstrated that the CuInSe/sub 2//CdS junction shows good performance following the temperature excursions up to 350/sup 0/C during the CdTe deposition.
