| titleOfInvention | A kind of perylene diimide electron transport material and its synthesis method and application |
| abstract | The invention belongs to the technical field of organic functional materials, and relates to a perylene diimide electron transport material, a synthesis method thereof, and an application in a trans-planar perovskite solar cell. The present invention takes the phenothiazine dioxide group as the core structure, connects the perylene diimide group at the 3-, 7-substitution positions of the phenothiazine dioxide structural unit, and controls the regulation by introducing different peripheral groups. The steric configuration of the molecule is used to construct perylene diimide electron transport materials with different twisted structures. The perylene diimide electron transport material provided by the invention has the advantages of stable condition, low cost, high electron mobility and the like. Compared with the trans-planar perovskite solar cells based on fullerene electron transport materials, the cells based on such electron transport materials have no retardation phenomenon under working conditions. In addition, lower fabrication cost, higher photoelectric conversion efficiency and better stability are favorable for promoting its large-scale commercial production. |
