Enhanced device performance of organic solar cells via reduction of the crystallinity in the donor polymer |
| 초록 |
In this work, we describe a new p-type conjugated copolymer (PPVQT-C8) composed of alternating p-divinylene phenylene and 3,3-dialkylquaterthiophene units for use in organic solar cell applications. To minimize the complexity of device processing and to maintain good mixing of the donor and acceptor materials in the bulk heterojunction photoactive layers during operation, we reduced the crystallinity of PQTs by introducing p-divinylene phenylene units between each pair of quaterthiophene units. Bulk heterojunction solar cells based on the PPVQT-C8:PC60BM blend were fabricated, and their performances were optimized. The nanophase separation of copolymer:PCBM blend layers was found to be correlated with reduced crystallinity in the copolymer. The dependence of solar cell performance on composition ratio and thermal treatment was systematically studied. |
