Abstract

Polytriarylamines have attracted significant interest as hole transport materials for organic electronics. Herein we report the synthesis of a polytriarylamine (PTAA) using the Suzuki polycondensation reaction. The Pd-based catalytic system was optimized to obtain a polymer with a high molecular weight and low polydispersity. The synthesized PTAA polymer was evaluated as a hole transport material in perovskite solar cells with n-i-p configuration. The devices showed an improved power conversion efficiency of 17.6% and an open-circuit voltage of 1.06 V, whereas the referenced cells based on commercial PTAA delivered a lower efficiency of 16.7% and an open-circuit voltage of 1.02 V. Thus, the proposed synthetic approach yields high-quality PTAA with improved electrical properties.
