Solar Cells, Inc. (SCI) has produced a 60.3 watt module with total area efficiency of 8.4% (NREL confirmed). The average total area efficiency of 60cm × 120cm modules manufactured on a developmental pilot line has increased to greater than 6.5% while the relative standard deviation has decreased to less than 10%. Modules routinely pass extensive stress testing. This paper summarizes the development of CdS/CdTe module manufacturing including product definition, process definition, and support programs. In addition the paper discusses our main conclusions to date and our future projections.
