Abstract

A series of thiazolothiazole-thiophene-based polymer hole-transporting materials (HTMs) are synthesized and applied into perovskite solar cells (PSCs). These polymer HTMs have good performance and stability without any dopants. The improved performance and stability of PSCs is attributed to the polymer HTMs' crystallinity which can be controlled by adjusting the thiophene units on the polymer backbone. The highest PCE of the polymer HTMs based PSCs reached 14.02%. The stability of the PSCs was shown by retaining 80% PCE of the original value after stored them in a N₂-filled glovebox for 113 days.
