This project supports the Solar America Initiative by: R and D that contributes to goal of grid parity by 2015; research to fill the industry R and D pipeline for next-generation low-cost scalable products; development of industry collaborative research; and improvement of NREL tools and capabilities for film silicon research. The project addresses both parts of film silicon roadmap: (1) amorphous-silicon-based thin film PV--amorphous and nanocrystalline materials, present '2nd generation' technology, 4% of world PV sales in 2007; (2) advanced R and D toward film crystal silicon--definition, large-grained or single-crystal silicon < 100 {micro}m thick; 3-8 year horizon; and goal of reaching 15% cells at area costs approaching thin films.

This presentation on wafer replacement cluster tool discusses: (1) Platform for advanced R and D toward SAI 2015 cost goal--crystal silicon PV at area costs closer to amorphous Si PV, it's 15% efficiency, inexpensive substrate, and moderate temperature processing (<800 C); (2) Why silicon?--industrial and knowledge base, abundant and environmentally benign, market acceptance, and good efficiency; and (3) Why replace wafers?--expensive, high embedded energy content, and uses 50-100 times more silicon than needed.
