Achieving Thickness-Insensitive Morphology of the Photoactive Layer for Printable Organic Solar Cells via Side Chain Engineering in Non-fullerene Acceptors (NFAs) |
| 초록 |
Recently, an organic solar cell having a high efficiency of over 15% has been reported, but reducing the performance degradation of the device according to the thickness of the photoactive layer is still important for successful commercialization of the printable organic solar cell. In this study, by synthesizing a new series of ITIC-based NFAs having alkyl or alkoxy groups, it is found that the bulk heterojunction morphology dependence on the thickness of the photoactive layer becomes more severe as the difference in the surface energy of the donor and acceptor increases. It is believed that present approach provides an important insight into the design of photoactive materials and morphology control for the printable OPVs using NFAs. |
