Capturing hot electrons

Nature Chemistry volume 2, pages 809–810 (2010)Cite this article

Subjects

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.
