Abstract
An enhanced photocurrent was observed for a Schottky-barrier cell with a mi xed solid consisting of metal-free porphyrin (H(2)tpp) and regioregular pol ythiophene (PTh) compared to similar cells with pure metal-free porphyrin o r pure PTh. This is because produced holes efficiently transport in the hig h-mobility PTh solid soon after a photoinduced electron-transfer from the P Th molecule to the photon harvesting H(2)tpp molecule.
