Scientists have experimentally verified a theory suggesting that hot electrons could double the output of solar cells. The researchers, from Boston College, have built solar cells that successfully use hot electrons to increase ...
(Phys.org)—At its heart, photovoltaics research is about finding materials with specific properties that make them good at absorbing sunlight and converting it into electricity. The best photovoltaics materials are semiconductors ...
Solar cells can now be made so thin, light and flexible that they can rest on a soap bubble. The new cells, which efficiently capture energy from light, could offer an alternative way to power novel electronic devices, such ...
