Researchers 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… »

Previous attempts at making 3D photonic crystals have resulted in devices that are only optically active (they can’t turn electricity to light or vice versa). A group of researchers, led by researchers from the University of Illinois, have managed to develop the first optoelectronically active 3D photonic crystal. The development could enable new advancements for… »
