By Damir Beciri
One Comment26 April 2012

yablonovitch-solar-cell-1Researchers from the University of California, Berkeley, came across a relatively simple solution based on a mathematical connection between absorption and emission of light that could lead to improvement of flat-plate solar cell efficiency. Although their concept is counterintuitive, the researchers managed to demonstrate that solar cells which are able to emit light more efficiently… »
