| 제목 | Effects of Thermal Annealing on Bulk-Heterojunction Photovoltaic Devices with Perylenebis(dicarboximide) Derivatives as Electron Acceptors. |
| 초록 | Current progress on organic photovoltaic devices from the standpoint of increasing power conversion efficiency (PCE) is mainly attributed to the bulk heterojunction structure. Further increase of the PCE is required for commercial applications of organic photovoltaic solar cells. The search of new materials with good performance characteristics as well as the improvement in the device fabrication has been a subject of importance. Perylene diimide derivatives (PDIs) are good candidates as electron accepting and transporting materials for bulk-heterojunction photovoltaic device, because PDIs have large molar absorption coefficients, good electron accepting properties and possible generation of highly conducting direction along the π- π stacking axis. We will compare the optical and thermal properties of no functional group substituted swallow tailed PDI (PDI-C9) and pyrrolidyl group substituted one (5-PDI). And the effects of thermal annealing on the photovoltaic properties with PDIs as electron acceptors and P3HT as an electron donor will be presented. |
