The formation of thin films of copper indium diselenide (CIS) on 929 cm[sup 2] (12 in[times]12 in) substrates and subsequent processing into photovoltaic devices and monolithically-interconnected modules is described. Improved temperature-time profiles in the selenization step have resulted in solar cells with a total area conversion efficiency of 12.5%. The effect of Cu/In ratio on the performance of such devices is reported. Standard characterization techniques are described, and temperature-dependent studies are shown to provide further valuable information. Device and material properties are also reported for the quaternary CuIn(Se,S)[sub 2]. Successful module development required the solution of many area and scribing related problems, including the problem of adhesion. A new interconnect and module technology has been validated by the achievement of a 9.7% active area conversion efficiency for a 20 cell module. The projected performance of manufactured modules is discussed in terms of proven module efficiencies.
