Description

technical field

[0001] The invention belongs to the technical field of heterocyclic compounds containing three or more heterocyclic rings, and relates to a class of compounds containing bitriazine groups and their application as three-dimensional electron acceptor materials. Background technique

[0002] The development and utilization of solar energy is expected to become a solution to energy and environmental problems faced by the world. It is a feasible way to develop photovoltaic technology and realize the commercialization of solar cells. At present, inorganic solar cells have disadvantages such as unenvironmental protection, high energy consumption, and long energy repayment time in the preparation process, while organic photovoltaics with abundant material sources and solution processability have great potential, which is particularly eye-catching.

[0003] The active layer of organic photovoltaic materials is usually made of a blend film of electron donor material (p...
