Fig. 2: Photovoltaic performances of PSCs.

a The schematic diagram of PSCs structure. b Zeta potential of TiO2 and TiO2/TFMS films surface. c Surface potential distribution of TiO2 and TiO2/TFMS films. d Computed differential lifetimes through fitting the TRPL spectra. e J-V curves (reverse scan) of the champion TiO2-based and TiO2/TFMS-based PSCs with an active area of 0.08 cm2. The illustration shows the stabilized power output of PSCs. f Distribution histograms of PCE of TiO2-based PSC and TiO2/TFMS-based PSCs, 30 in each group. g The Mott-Schottky curve of PSCs. h The EIS curve of PSCs. i J-V curves (reverse scan) of the champion SnO2-based and SnO2/TFMS-based PSCs with an active area of 0.08 cm2.
