Presentation for the 2009 University Scholars Day at the University of North Texas discussing research on the impact of indigenous movements in Latin America.

This project supports the Solar America Initiative by: (1) providing a consistent framework for analyzing and comparing power system costs and performance across the range of solar technologies and markets, PV, solar heat systems, CSP, residential, commercial and utility markets; (2) developing and validating performance models to enable accurate calculation of levelized cost of energy (LCOE); (3) providing a consistent modeling platform for all TPP's; and (4) supporting implementation and usage of cost models.

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.

Presentation for the 2008 University Scholars Day at the University of North Texas discussing research on eveningness, insomnia, and delayed sleep phase syndrome in university students.

This project supports the Solar America Initiative by carrying out work on target topics identified for Photovoltaic Systems: (1) Improving cell and module efficiency of thin film Cu(In,Ga)Se2 materials; (2) Implementing the Science and Technology Facility (S&TF) and the Process Development and Integration Laboratory (PDIL) to facilitate laboratory/industry interaction in developing PV manufacturing technologies; (3) Addressing industrial issues in materials and manufacturing processes with the objective to lower the cost of PV power; (4) Providing technology transfer efforts to accelerate transition of thin film PV technology to market and deployment; (5) Assisting R&D efforts to asses and improve reliability and stability of thin film PV products; and (6) Assist the SAI TPPs in technical matters related to CIGS PV technology.
