Researchers using novel materials to build photovoltaic cells say their efforts could nearly double the efficiency of silicon-based solar cells.
The cells being developed by teams from the University of Arkansas and Arkansas State University have the potential to achieve a light-to-energy conversion rate, or solar efficiency, of 40 percent or better, according to the researchers.
The photovoltaic cells are intended for use in satellites and space instruments. Currently, the silicon-based solar cells that NASA uses in its satellites and instruments have efficiencies of only up to 23 percent, according to NASA statistics.
And today it was announced that the … Read more
