Compositions based on indenone arylamine modified poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] and uses

Abstract

The application discloses a composition based on indanone arylamine modified poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] and application, synthesizes two kinds of organic small molecules to modify the surface of poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] (PTAA), so that the hydrophobic property of PTAA is improved, and the growth of a perovskite film is facilitated.Compared with original PTAA, the PTAA-L01 / PTAA-L02 composition improves the open voltage, fill factor and overall efficiency of a perovskite solar cell, and the hole mobility and conductivity are greatly improved.The material is reasonable in raw material and cost, and can be efficiently applied to a perovskite solar cell to obtain excellent photoelectric conversion efficiency.The application explores the influence of an indanone end group on the performance of a hole transport material, and provides an experimental basis for a perovskite solar cell.
