Researchers sets New Record for Silicon-based Multi-junction Solar Cell with 30.2 Percent Efficiency Updated On Thu, Nov 10th, 2016 by Saurenergy Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with the Austrian company EV Group (EVG) has developed a silicon-based multi-junction solar cell with two contacts and record efficiency of 30.2 % exceeding theoretical limit of silicon solar cells. To achieve this efficiency, researchers used a “direct wafer bonding” process to transfer a […] Read more
