Organic photovoltaics

Some like it hot

Nature Materials volume 12, pages 5–6 (2013)Cite this article

Subjects

Excitation of organic donor–acceptor systems with high-energy light can produce hot charge-transfer states that are delocalized across the heterojunction and readily dissociate. Two studies now reveal the dynamics of this process and pave the way towards unravelling the details of the molecular landscape that favours fast photocarrier generation.
