Carbazole-based material: Synthesis, Characterization and Application as hole transporting material in perovskite solar cells
Résumé
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 is reported. Its preliminary application in Cs0.08FA0.80MA0.12Pb(I0.88Br0.12)3 mixed perovskite solar cell (PSC) lead 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.
