The power conversion efficiencies of poly(3-hexylthiophene)/[6,6]-phenyl-C-61-butyric acid methyl ester (P3HT/PCBM) bulk heterojunction organic solar cells were increased through the addition of small amounts (1-10%) of metalloporphyrin-oligothiophene conjugates. The effectiveness of these porphyrin additives was found to increase in the order free-base < Co < Zn < Ni < Cu, with the efficiency being enhanced by up to 17% for the terthiophene-substituted Cu(II)-porphyrin, pointing to an important effect of the metal center.
