Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells
13 May, 2019
Solar cells made of perovskite hold much promise for the future of solar energy. However, the material degrades quickly, severely limiting its efficiency and stability over time. Researchers have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing ...
Copper oxide photocathodes: Laser experiment reveals location of efficiency loss
9 May, 2019
Solar cells and photocathodes made of copper oxide might in theory attain high efficiencies for solar energy conversion. In practice, however, large losses occur. Now researchers has been able to use a sophisticated femtosecond laser experiment to determine where these losses take place: not so much ...
