UCSD nanostructures will raise thin-film solar cell efficiency

Thanks to nanostructures that scatter and channel light, University of California, San Diego electrical engineers are working toward thin-film “single junction” solar cells with the potential for nearly 45 percent sunlight-to-electricity conversion efficiencies. This UC San Diego effort to break the theoretical limit of 31 percent efficiency for conventional single junction cells recently received a big funding boost from the U.S. Department of Energy`s Solar America program.
