Dual‐Functional Upconverter‐Doped TiO₂ Hollow Shells for Light Scattering and Near‐Infrared Sunlight Harvesting in Dye‐Sensitized Solar Cells

Upconverter-doped TiO2 hollow shells prepared by a simple one-pot hydrothermal method can be used as a dual-functional top-layer in the photoanodes of dye-sensitized solar cells, not only improving the light scattering, but also enhancing near-infrared light harvesting of the DSSC cells.
