Jester, T L

This report describes work that focused on reducing the cost per watt of Cz silicon photovoltaic modules under Siemens Solar Industries' (SSI) DOE/NREL Photovoltaic Manufacturing Technology (PVMaT) 4A subcontract. SSI researchers deployed new module designs, realized improvements in yield of more than 25%, and implemented statistical process control (SPC). They have described yield improvements in detail and reported on the deployment of SPC in critical process steps. The sum of all improvements resulted in a greater than 17% cost per watt reduction in manufacturing.
