The major obstacle to developing a high-efficiency CdTe/CdS cell has been the lack of reproducibility. A number of process modifications have been made to overcome this. Some progress was made with a cell in which the CdTe is deposited onto a transparent ohmic contact; however, difficulties continued to be encountered in controlling the CdTe conductivity. Effort has been redirected to a cell in which the CdTe is deposited onto the CdS, leaving an exposed CdTe surface to which ohmic contact can be made. Research on the CuInSe/sub 2//CdS cell has established that high efficiency can be achieved over a broad CuInSe/sub 2/ composition range and a wide substrate temperature range.
