Solarbuzz reports that SANYO Electric has broken its own record for what the company says is the world’s highest energy conversion efficiency in practical sized (100 cm2 or more) crystalline silicon-type solar cells, by achieving an efficiency of 22% at the research level for its proprietary HIT solar photovoltaic cells. The previous highest efficiency had been 21.8%.
Action on Capital Hill: The Gavel reports that the House Committee on Science and Technology’s Subcommittee on Energy and Environment today explored means to advance solar energy research and technologies.
