Cubic CeO2 nanoparticles as mirror-like scattering layers for efficient light harvesting in dye-sensitized solar cells.

A new type of bilayered photoanodes with cubic CeO2 nanoparticles as mirror-like scattering thin layers was prepared via a screen-printing technique for dye-sensitized solar cells (DSSCs). The light harvesting efficiency was significantly enhanced due to the mirror-like light scattering effect, resulting in noticeable similar to 17.8% improvement of light-to-electric conversion efficiency.
