The efficiency of photovoltaic materials is compromised by their inability to capture all the energy absorbed when excited by high-energy photons. Such absorption creates 'hot' electrons, and now their transfer from excited lead selenide nanocrystals to an electron acceptor provides a necessary initial step towards tapping their 'lost' energy.
