Bright Automotive was counting on a U.S. government loan to build a factory for its hybrid utility van, but after three years of waiting, it's forced to shut down.
Scientific research and entrepreneurship in clean energy is alive and well at the ARPA-E Summit.
The political uproar over failed solar company Solyndra risks eroding support for valuable clean-energy technology programs and could starve promising solar companies of financing.
There's a race to produce solar cells from CIGS that approach silicon's efficiency. HelioVolt says it's getting there--and fast.
You've heard about them for years, but CIGS solar cells are finally coming to market.
CIGS aren't on the market yet, but there's a lot of money floating around. And the Miasole layoff rumors aren't true, says company.
Chinese PV maker unveils semitranslucent photovoltaics that look like mirrors, windows, and skylights.
Researchers achieve efficiency gains with cell that uses "earth-abundant" materials. Cheaper thin-film cells rely on comparatively rare or costly metals.
1366 Technologies says that it can get 18 percent efficiency with standard silicon cells but changes in the solar industry mean it won't be able to produce cells itself.
Building-integrated photovoltaics won't make your inner architecture critic wince, but you may have to make a trade-off on efficiency.
