Abstract: The preparation of hole-transporting materials with high hole mobility is of great significance for
the commercial application of perovskite solar cells. 5,10,15,20-tetra[3,5-di(tert-butyl)phenyl]-β,β′-
tetranaphthoquinone[6,7-g]zinc porphyrin (T1), a black porphyrin molecule with high thermal stability and
full visible light absorption capability was synthesized. The photophysical properties, electrochemical
properties, thermal stability and film forming properties of T1 were investigated by UV-Vis, cyclic
voltammetry, SEM and TGA. The results indicated that the highest occupied molecular orbital energy level
of T1 was –5.13 eV, which was similar to that of 2,2′,7,7′-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-
spirobifluorene (spiro-OMeTAD) (–5.11 eV), could be well matched with that of the perovskite material,
methylammonium lead iodide. The short-circuit current, open-circuit voltage, fill factor and photoelectric
conversion efficiency of the perovskite solar cell with T1 as hole transport layer without any dopant were
2
23.86 mA/cm , 0.91 V, 61.9% and 13.43%, respectively. The photoelectric conversion efficiency of the
perovskite solar cell based on T1 was much higher than that of spiro-OMeTAD-based perovskite solar cell
prepared under the same condition (11.63%).
