Uniform flux dish concentrators for photovoltaic application

Description: Researchers at the National Renewable Energy Laboratory (NREL) have designed a unique and innovative molded dish concentrator capable of producing a uniform flux profile on a flat target plane. Concentration levels of 100--200 suns, which are uniform over an area of several square inches, can be directly achieved for collection apertures of a reasonable size ({approximately}1.5-m diameter). Such performance would be immediately applicable to photovoltaic (PV) use. Economic concerns have shown t… more

Energy technologies at Sandia National Laboratories: Past, Present, Future

Description: We at Sandia first became involved with developing energy technology when the nation initiated its push toward energy independence in the early 1970s. That involvement continues to be strong. In shaping Sandia's energy programs for the 1990s, we will build on our track record from the 70s and 80s, a record outlined in this publication. It contains reprints of three issues of Sandia's Lab News that were devoted to our non-nuclear energy programs. Together, they summarize the history, current act… more

Government policy and market penetration opportunities for US renewable energy technology in India and Pakistan

Description: Some US renewable energy industries are now looking abroad, especially to the rapidly developing Asia-Pacific region, in order to increase sales and expand markets. The developing world appears in principle to be an important market for renewable energy technologies. These international markets have proven extremely difficult to penetrate, and the US competitive position is threatened by strong, well-organized, government-supported competition from Japan and Western Europe. For example, US phot… more

Final report on Synthesis of silane and silicon in a nonequilibrium plasma jet

Description: The original objective of this program was to determine the feasibility of high volume, low-cost production of high purity silane or solar cell grade silicon using a nonequilibrium plasma jet. The emphasis was changed near the end of the program to determine the feasibility of preparing photovoltaic amorphous silicon films directly using this method. The nonequilibrium plasma jet is produced by partially dissociating hydrogen to hydrogen atoms in a 50 to 100 Torr glow discharge and expanding th… more
