Asymmetric indenothiophen core-based n-type Semiconductor and its Application to Non-fullerene type Polymer Solar Cells |
| 초록 |
New asymmetric n-type semiconducting molecule (PhITBD) with indenothiophene core was designed and synthesized by tethering 2-(benzo[c][1,2,5]-thiadiazol-4-ylmethylene)-malonitrile (BM) as terminal groups in application of polymer solar cell (PSC). Instead of a symmetric structured molecule of IDT-2BM, the PSCs with asymmetric PhITBD exhibited much improved power conversion efficiencies (PCE) of 6.57%. The increase in PCE value of PhITBD-based PSC was mainly attributed to the enhanced photovolatic properites induced by complementary light absorption, morphological improvement, and balanced charge carrier transport in the active layer. Owing to the effective morphological control and absorption enhancement, asymmetric structured n-type conjugated molecule can be recognized as another good candidate to improve the performance of bulk heterojunction non-fullerene type PSCs. |
