摘要：

Three star-shaped truxene-based small molecules(namely TXH,TXM,TXO) were synthesized,characterized and used as hole-transporting materials(HTMs) for perovskite solar cells(Pv SCs). The device based on TXO delivered a respectable power conversion efficiency(PCE) of 7.89% and a high open-circuit voltage(Voc) of 0.97 V,which far exceeded the values of the devices based on other two small molecules. The highest PCE for the device based on TXO is mainly contributed from its lowest series resistance(Rs) value and largest short-circuit current(Jsc) value under the same circumstances. All these results indicate that TXO is a promising HTM candidate for Pv SCs.
