Cu-doped mesoporous TiO2 interlayer for highly efficient and stable hybrid perovskite solar cells
{{output}}
Titanium dioxide (TiO2)-based electron transport layers (ETLs) are widely used in perovskite solar cells (PSCs) but suffer from low electron mobility, deep-level defects, and detrimental interfacial recombination, which lower open-circuit voltage (VOC) and sho... ...
