K. Takahashi et al., Organic solid-state solar cells with a mixture of monomeric porphyrins forlight-harvesting and regioregular polythiophene for charge transport, SYNTH METAL, 123(1), 2001, pp. 91-94
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. (C) 2001 Elsevier Sc
