Researchers from the Germany Center for Solar Energy and Hydrogen Research (ZSW) have broken a new efficiency record for thin-film copper indium gallium diselenide solar cells.
The researchers produced a 20.3 percent efficient cell, only a fraction less than the best multi-crystalline cells on the market. However, producing a cell in a lab is much different than mass production. CIGS cells typically reach about 10-11 percent when manufactured in large numbers.
