Cost and reliability improvement for CIGS-based PV on flexible substrate

When this TFPPP subcontract was partially completed, Global Solar Energy (GSE) was charged with simultaneously executing a dramatic increase in production capacity, with the planning and construction of two entirely new production facilities for thin film CIGS PV (in Tucson, AZ and Berlin, Germany). The expansion was the major focus of the organization for about 24 months, and in some cases diverted resources that had been allocated to development, including this subcontract. However, since the expansion required entirely new production equipment for all phases of the thin film deposition and "back-end" operations, it also provided a unique opportunity to execute on the goals of this subcontract in ways we had not envisioned. Major improvements in cost and reliability, goals of this subcontract, could now be addressed in the design stages for the 'Gen2' plants and equipment, opening up large opportunities, and leveraging what had been learned at GSE with the existing 'Gen1' production equipment and processes.
