| titleOfInvention | Cathode interface modification material, preparation method and application thereof |
| abstract | The invention relates to the technical field of solar cells, in particular to a solar cellThe cathode interface modification material has a structural general formula shown as formula I: wherein R1 is selected from H, Any one of the above; r2 is selected from Any one of them. The cathode interface modification material provided by the invention has higher photoelectric conversion efficiency, and can be applied to organic polymer solar cells, particularly non-fullerene solar cells. According to the cathode interface modification material, the side groups with gradually increased steric hindrance are introduced to the two sides of the perylene bisimide, so that perylene bisimide molecules become more distorted, and the regulation and control of the molecule accumulation state can be realized, thereby optimizing the appearance of the film and the efficiency of devices, and improving the photoelectric conversion efficiency. |
