Conversion of Light into Electrical Power in a Molecular Layer Structure

Abstract
A stepwise change in the standard redox potential with a total drop of about 0.5 eV has been realized in a molecular structure containing 3 different chromophores in successive molecular layers. With red light the molecular structure delivers a current yield of 0.3 holes per absorbed photon. Current yield and power conversion efficiency of the molecular converter are expressed in simple formulas in terms of experimentally accessible quantities.
