Nanostructured layers of metal oxides with very large bandgaps (Eg > 5 eV), such as ZrO2 and HfO2, were used as photoelectrodes in semitransparent perovskite solar cells (PSCs) with the device architecture of glass/FTO/c-TiO2/ZrO2 (or HfO2)/CH3NH3PbI3/PTAA/PEDOT:PSS/FTO/glass.
The obtained PSCs were used as top elements for manufacturing high-performance four-terminal tandem perovskite-silicon solar cells. The comparative analysis of photovoltaic parameters measured for PSCs, crystalline silicon (c-Si) solar cells and tandem PSC/c-Si solar cells demonstrated
that the application of very large-bandgap materials allows to improve the PSC performance and to increase the efficiency of tandem PSC/c-Si solar
cell up to ~24% in comparison with a standalone c-Si solar cell.

Keywords: photoelectrode, perovskite, solar cells, tandem solar cells, solar photovoltaics.
