Solar cells may one day use microscopic chunks of semiconductors known as quantum dots to produce more power and cut production costs, according to an article to be published Dec. 16 in the journal Science.
Conventional solar cells struggle to convert high-energy photons in sunlight into electricity, said Matt Beard, a senior scientist at the National Renewable Energy Laboratory and one of the article’s authors.
