Molecular modification of spiro[fluorene-9,90- xanthene]-based dopant-free hole transporting materials for perovskite solar cells

In this work, novel organic molecules are designed, synthesized, and introduced as the hole transport materials on the top of perovskite layer in planar n−i−p heterojunction perovskite solar cells (PSCs). This data set contains the optoelectronic (UV-Vis, conductivity) and compositional characterization of the resulted thin films (XRD, SEM, AFM) and photovoltaic properties of the fabricated solar cells (J-V curves, carrier recombination, power conversion efficiency, hysteresis effect). The resulting perovskite films were also characterized by steady-state photoluminescence (PL), time-resolved PL (TRPL) and electrochemical impedance spectroscopy (EIS) measurements.
