Issue Date: | 2013 | Source: | SYNTHETIC METALS, 178, p. 56-61 | Abstract: | The power conversion efficiencies of poly(3-hexylthiophene)/[6,6]-phenyl-C61-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. | Notes: | Sessler, JL (reprint author), Univ Texas Austin, Dept Chem & Biochem, Austin, TX 78712 USA. sessler@cm.utexas.edu | Keywords: | Porphyrins; Organic photovoltaics; Bulk heterojunctions; Ternary blends | Document URI: | http://hdl.handle.net/1942/15801 | ISSN: | 0379-6779 | e-ISSN: | 0379-6779 | DOI: | 10.1016/j.synthmet.2013.06.013 | ISI #: | 000324227200010 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2014 |
