Enhanced performance of inverted polymer solar cells using modified polyethylenimine ethoxylated |
| 초록 |
Surface treatment of ITO electrode using polyethylenimine ethoxylated (PEIE) can simplify the fabrication of inverted solar cells because lowered work function of ITO makes it possible to fabricate the devices without an electron transport layer. However, dipole-mediated work function modification of PEIE only occurred near the interface, mostly within one or two monolayers. Furthermore, because the intrinsic nature of PEIE is a non-conducting insulator, the PEIE layer thicker than allowed may have a high interlayer resistance. In this work, we have introduced modified PEIE on inverted solar cells based on PTB7-Th:PC71BM. The modified PEIE exhibited better charge extraction property by reducing interfacial resistance between ITO and the active layer, thereby enhancing the performance of devices. |
