Electrophoretic deposition of donor–acceptor nanostructures on electrodes for molecular photovoltaics
Hiroshi Imahori
Electrophoretic deposition of donor–acceptor nanostructures onto electrodes is reviewed in terms of light-to-electrical energy conversion. Various donors and acceptors and their composites have been deposited electrophoretically onto a nanostructured SnO2 or TiO2 electrode which exhibits photocurrent generation. In particular, bottom-up self-organization of porphyrin and fullerene molecules onto the nanostructured SnO2 electrodes has led to highly efficient photocurrent generation with an incident photon-to-current efficiency (IPCE) of up to
60%. Such examples will give us many valuable insights into the design of organic molecular electronics including solar cells, organic transistors, and light-emitting devices.
