Issue Date: | 2016 | Publisher: | ELSEVIER SCIENCE SA | Source: | SYNTHETIC METALS, 218, p. 1-8 | Abstract: | Ternary organic photovoltaic devices were prepared through the addition of small amounts of metalloporphyin-terthiophenes to two established low bandgap polymer:fullerene blends. The methodology afforded a PCDTBT:PC71BM-based device that displayed an initial power conversion efficiency of 5.1%, an increase of 16% when compared to the binary blend. Among the range of metalloporphyrins considered in this study, the Cu(II)-porphyrin derivatives were found to result in the most significant efficiency improvements. | Notes: | [Stoltzfus, Dani M.; Sessler, Jonathan L.] Univ Texas Austin, Dept Chem, Austin, TX 78712 USA.
