Description

technical field [0001] The invention belongs to the technical field of organic functional materials, and relates to a hole transport material with a phenoxazine core structure, a preparation method thereof, and an application in a perovskite solar cell. Background technique [0002] As an emerging solar cell technology, Perovskite Solar Cell (Perovskit Solar Cell) is developing rapidly, and its photoelectric conversion efficiency has exceeded 23% in just a few years, and was rated as one of the top ten scientific discoveries in 2013 by Science magazine one. Perovskite solar cells not only have excellent photovoltaic performance, but also have low requirements on the purity of materials, and can be prepared by a simple solution method at room temperature, which greatly simplifies the production process and reduces the production cost. The large-scale production and industrialization of mining solar cells provide the possibility, so that it has great potential for commercial ...
