- Abstract
- The packing effects induced by the hydrophilic ethylene glycol oligomer side chains occurred in a P3HT:PC61BM mixture upon the addition of small amounts of BP93 (containing 7 mol% PEGT blocks), leading to an enhanced crystallinity among the P3HT molecules, even in a P3HT: PC61BM blend. The enhanced crystallinity improved the charge transport and current density (8.3-11.1 mA/cm(2)) and increased the power conversion efficiency (3.1-3.9%) in an organic solar cell.
