Exciton fission – one photon in, two electrons out

A publication by AG Ernstorfer has appeared in Nature, which may make it possible in the future to significantly improve the efficiency of solar cells by exploiting the heat generated.

Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy. Since the days of Max Planck and Albert Einstein, we know that light as well as electricity are quantized, meaning they come in tiny packets called photons and electrons. In a solar cell, the energy of a single photon is transferred to a single
