Toward the Realization of Practical Diketopyrrolopyrrole-based Small Molecule for Improved Efficiency in Ternary BHJ Solar Cells |
| 초록 |
An easily accessible DPP-based small molecule (DMPA-DTDPP) has been synthesized by a simple and efficient route. The resulting molecule when incorporated into a P3HT:PCBM-based BHJ solar cell is found to significantly improve the efficiency. The utility of DMPA-DTDPP as an additive yields an increase in the short circuit current density (Jsc) because DMPA-DTDPP serves as an energy funnel for P3HT excitons at the P3HT:PCBM interfaces, resulting in improved overall power conversion efficiency (PCE) by 35%, compared to the P3HT:PCBM control device. Considering the trouble-free and cost effective synthesis of DMPA-DTDPP into account, we must emphasize that DMPA-DTDPP comes in pretty handy in high-performance solar cells. |
