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.
In a first, the CEO of the oil giant calls for a carbon tax, rather than a cap and trade. Meanwhile, small solar start-ups HelioVolt and Spectrawatt hit hurdles.
Thin-film solar company HelioVolt signs on Architectural Glass & Aluminum to build curtain walls, or large windows, with integrated solar cells.
Thin-film solar power companies want to integrate solar cells with buildings, but they still have a way to go.
Solar-cell vendor has laid off 40 employees, according to a report. If true, it would cap off a tough year for the once-hot CIGS vendor.
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.
Nanosolar's production machine can turn out 100 feet of cells per minute, making it more cost-effective than existing manufacturing techniques, the company claims.
Researchers achieve efficiency gains with cell that uses "earth-abundant" materials. Cheaper thin-film cells rely on comparatively rare or costly metals.
