Dream of energy-collecting windows is one step closer to reality

Discovery could lower cost and expand possibilities for building-integrated solar energy collectionResearchers at the University of Minnesota and University of Milano-Bicocca are bringing the dream of windows that can efficiently collect solar energy one step closer to reality thanks to high tech silicon nanoparticles.The researchers developed technology to embed the silicon nanoparticles into what they call efficient luminescent solar concentrators (LSCs). These LSCs are the key element of windows that can efficiently collect solar energy. When light shines through the surface, the useful frequencies of light are trapped inside and concentrated to the edges where small solar cells can be put in place to capture the energy.The research is published today in Nature Photonics, a peer-reviewed scientific journal published by the Nature Publishing Group.
