文摘

Upconversion (UC) Er,Yb-CeO2 hollow spheres by carbonaceous spheres as template. Both TiO2 and UC hollow spheres assembled to bilayer structure in DSSCs. Cell efficiency improved 27% compared to the cell without scattering layer. Improvement due to upconversion, scattering effect and higher dye-loading.
