Record Makes Thin-Film Solar Cell Competitive with Silicon Efficiency

We had some really great threads last year, with the following four nominated for the Thread of the Year award in this January's Environment Site Awards ceremony.

I think they're great and give a real sense of what the forum is capable of, so if you're looking for a reason to join, check these out.

Solar Energy Forum I have no doubt that we will be successful in harnessing the sun's energy.... If sunbeams were weapons of war, we would have had solar energy centuries ago. ~Sir George Porter

Record Makes Thin-Film Solar Cell Competitive with Silicon Efficiency

March 24, 2008

Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory have moved closer to creating a thin-film solar cell that can compete with the efficiency of the more common silicon-based solar cell.
The copper indium gallium diselenide (CIGS) thin-film solar cell recently reached 19.9 percent efficiency, setting a new world record for this type of cell. Multicrystalline silicon-based solar cells have shown efficiencies as high as 20.3 percent. The energy conversion efficiency of a solar cell is the percentage of sunlight converted by the cell into electricity.
