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… »

Even though silicon is one of the most abundant elements, the energy required to make silicon from sand is immense. A group of researchers from the Swiss Federal Institute of Technology in Lausanne (EPFL) developed a new nanopatterning technique which boosts the output of the cells, thus enabling manufacture of solar cells that are one… »

A team of researchers, led by Oak Ridge National Laboratory’s (ORNL’s) Jun Xu, created a 3D nanocone-based solar cell platform which boosts the light-to-power conversion efficiency of photovoltaics by nearly 80 percent. The technology substantially overcomes the problem of poor transport of charges generated by solar photons, which occur due to defects in bulk materials… »
