The synthesis and characterization of a novel oligomeric cyclic carbazole-based material (PCz1) for an application as hole transporter (HTM) in hybrid perovskite photovoltaic devices are reported. Its preliminary application in Cs0.08FA0.80MA0.12Pb(I0.88Br0.12)3 mixed perovskite solar cell (PSC) leads to a device power conversion efficiency of 18.04% which is comparable to that of the Spiro-OMeTAD reference cells (17.94%). In addition, the novel HTM is proved to act as a good barrier and protect satisfactorily the perovskite surface giving highly stable PSC devices.
