Abstract

We have synthesized 5, 10, 15, 20-tetrakis {4-[N, N-di(4-methoxylphenyl) amino-phenyl]-porphyrin (Po) and its cobalt complex cobalt-porphyrin (CoP) hole-transport materials for efficient perovskite solar cells. Both Po and CoP exhibit excellent hole mobility and favorable energetic alignment with perovskite for hole extraction. Our results clearly show that incorporation of cobalt atom into Po boosts the power conversion efficiency up to 16.9%, which is 14% higher than without cobalt atom. CoP based devices exhibit better stability than Po devices. The perovskite layers that are deposited on top of CoP exhibit better crystallinity compared to Po, which are supported by the X-ray diffraction and morphological studies. These results are further evident from time-resolved photoluminescence.
