Molecular Engineering of Azahomofullerene-based Electron Transporting Materials for Efficient and Stable Perovskite Solar Cells

In this work, novel azahomofullerene (AHF) is designed, synthesized, and introduced as the interlayer between the SnO2/perovskite interface 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.
