High-performance polymer solar cells with moderately reduced graphene oxide as an efficient hole transporting layer |
| 초록 |
In polymer solar cells consisting of active layer sandwiched between an ITO and a metal cathode, direct contacts between the active layer and electrodes lead to recombination of carriers and current leakage. Although conventional water-soluble poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) has been widely used as an HTL for more efficient hole collection, several groups have tried to replace PEDOT:PSS due to the several problems resulting in poor long-term stability. In this study, as an alternative PEDOT:PSS HTL, we demonstrate moderately reduced graphene Oxide (GO) films fabricated by a simple and fast thermal treatment of solution processed GO. Effect of conditions of thermal treatment on the cell-performances was investigated and stability of PSCs with moderately reduced GO was also compared to conventional systems including PEDOT:PSS HTL. |
