Abstract A hybrid conjugated molecule TTPA-TTF was designed and synthesized by combing a tetrathiafulvalene core with tetra-triphenylamine derivative functionalized at the 4,4',5,5'- positions. Studies revealed TTPA-TTF exhibits good thermal stability and hole mobility. To explore its primary application as hole-transporting material in perovskite solar cells, TTPA-TTF -based cells exhibited a power conversion efficiency of 10.95% without the use of any p-type dopants.
