Abstract
We synthesized three isomeric subpopulations of bisadduct analogues of [6,6]-phenyl-C-61-butyric acid methyl ester (bis-PCBM) via tether-directed control. Bulk heterojunction solar cells prepared using these isomers together with poly(3-hexylthiophene) (P3HT) resulted in an increase of J(sc) from 72.4 to 79.6 A m(-2), and an improvement in fill factor from 0.55 to 0.62, both with a V-oc of 0.72 V resulting in an overall enhancement of the power conversion efficiency (PCE) from 2.9% to 3.5%, compared to conventional bis-PCBM.
