Description

Yuki Sakamoto and a large team craft an X-shaped chiral molecule that carries electrons for use in perovskite solar cells, a role usually played by fullerene materials. The design starts from a figure-eight ring system bearing electron-pulling groups, then attaches four more strong electron acceptors through thiophene links. The shape lets it form smooth glassy films from solution with good electron conduction.

Solar cells using it as the electron-transport layer converted about twenty-one percent of sunlight, matching the standard fullerene benchmark. Its mirror-image forms also sorted electron spin with striking efficiency, up to eighty percent asymmetry, thanks to a chirality effect on spin. The authors present the ring as a versatile building block for organic electronics.
