    Recent progress in the optical and electrical performance of monolithic interconnected modules (MIMs) has produced an interest in manufacturing large quantities of cells for evaluation. Information resulting from this evaluation is necessary to produce and optimize a TPV system, where a large number of devices with a nominal performance must be available for insertion into series/parallel electrical networks. In this work over 130 wafers comprising three different device designs were grown, with representative wafers from each design processed in a pilot-line manufacturing environment. This paper describes the material growth, device design and processing, and electrical performance of these cells.
