This research was conducted to fabricate CuInSe/sub 2//CdS solar cells on well-characterized CuInSe/sub 2/ single-crystal wafers in order to improve our understanding of thin-film polycrystalline devices. CuInSe/sub 2/ wafers were supplied to the Institute of Energy by K. Bachmann of North Carolina State University. CdS was deposited onto the wafers to make CuInSe/sub 2//CdS heterojunctions. Some wafers were treated in a Se atmosphere to lower the resistivity and to homogenize properties through the wafer. Not all wafers were single-crystal. The wafers were characterized in terms of resistivity, carrier type, composition and crystallographic structure. The CuInSe/sub 2//CdS cells had efficiencies over 4% and open-circuit voltages over 0.45 V. The number of wafers and their quality limited the device performance achievable in this work.
