ZrO2–Y2O3 nanostructured systems with different yttria content (Y2O3 = 0, 3 and 10 mol.%) were synthesized under hydrothermal conditions and their structural, optical and electronic properties were investigated. Using ZrO2–Y2O3 systems the electron-conductive thin-film photoelectrodes were fabricated and used to develop the perovskite solar cells (PSCs) with the device configuration glass/FTO/ZrO2-Y2O3/CH3NH3PbI3/spiro-MeOTAD/ Au. The comparative studies of the PSCs photovoltaic parameters revealed that under 1000 W/m2 (AM1.5G) illumination solar cells with ZrO2–Y2O3 photoelectrodes demonstrated considerably higher power conversion efficiency in comparison with PSCs based on the undoped ZrO2 photoelectrodes.
