tandem solar cells tagged posts

Physics researchers at Lund University in Sweden recently succeeded in constructing small solar radiation-collecting antennas—nanowires—using three different materials that are a better match for the solar spectrum compared with today’s silicon solar cells. As the nanowires are light and require little material per unit of area, they are now to be installed for tests on satellites, which are powered by solar cells and where efficiency, in combination with low weight, is the most important factor...
