AI Technical Summary
Existing methods for synthesizing hole transport materials suffer from problems such as expensive catalysts, low yields, and poor economic efficiency, making them unsuitable for large-scale production. Furthermore, traditional materials are chemically unstable when in contact with perovskites.
Based on the chlorination reaction to generate 3,7-dichlorophenthiazide, the process of synthesizing hole transport materials is optimized through a series of coupling, condensation and hydrolysis reactions using specific catalysts and solvents, including the use of catalysts such as Pd(dppf)Cl2 and palladium acetate and specific solvents to improve reaction efficiency.
The synthesis of hole transport materials with high efficiency and easy scale-up has been achieved, improving yield and economy. The materials have good interface passivation ability and are suitable for perovskite solar cells.
