✦ Synopsis

Conversion of red light into an electrical current has been investigated in a molecular structure containing three different chromophores in successive molecular layers. A stepwise change in the standard redox potential with a total drop of about 0.5 eV facilitates downhill separation of electron-hole pairs. The structure delivers a current yield of 0.3 hole per absorbed photon. The performance of the structure is described with experimentally accessible quantities.
