Development of CdTe module manufacturing

Solar Cells, Inc. has produced a 60.3 watt thin‐film CdTe module with total area efficiency of 8.4%. The average total area efficiency of 60 cm×120 cm modules manufactured on a developmental pilot line has been demonstrated at greater than 7.0% while the relative standard deviation has decreased to less than 10%. Modules routinely pass extensive stress testing. SCI has initiated the development of a 20 MW line based on the pilot line process. This paper summarizes the status of this development including product definition, process definition, equipment engineering and support programs.
