A series of nanostructured layered photoelectrodes based on Y2O3 stabilized ZrO2 (Zr:Y) with varied Y2O3 concentration was prepared and used for constructing perovskite solar cells (PSCs). The structural, optical and energy characteristics of the photoelectrodes were investigated. The studies of the photovoltaic (PV) performance for the PSCs with different types of Zr:Y photoelectrodes and the device architecture of FTO/cTiO2/Zr:Y/CH3NH3PbI3/PTAA/PEDOT:PSS/FTO were provided. The results obtained demonstrate a possibility of PV application of the nanostructured oxide materials with a very wide bandgap exceeding 5 eV. The prepared devices were used for constructing of four-terminal tandem PSC/c-Si solar cell, in which PSC was used as a top sub-cell. By tuning the optical and structural parameters of Zr:Y photoelectrodes we have found the optimal parameters of tandem PSC/cSi solar cell for reaching the best performance under AM.1.5G illumination conditions.
