Abstract: Two novel fluorene-based hole transporting materials(HTMs)were synthetised to be used in perovskite solar cells(PSCs).C102 was designed based on C101 by simply linking two carbon-carbon single bonds to compose a"dispiro"structure.Their typically similar features cause them sharing almost the same energy levels.However,their photovoltaic performances are quite different.The PSC that contained
