The invention belongs to the technical field of organic functional materials, and discloses a hole transporting material with phenoxazine as a core structure and a preparation method thereof, and application on a perovskite solar cell. The hole transporting material has a phenoxazine derivative as a core structure, and N,N-dimethoxyaniline is bonded to both ends, and has the characteristics of stable natural conditions, low cost, high hole mobility and high conductivity. Compared with the conventional hole transporting material Spiro-OMeTAD, the hole transporting material containing phenoxazine core structure designed and developed by the invention has lower production cost and comparable photoelectric conversion efficiency; the invention opens up a new type of broad The application of the hole transporting material with phenoxazine as the core structure provides a new choice for the preparation of highly efficient and stable perovskite solar cells in the hole transporting material. |
