摘要：

Highly homogeneous, well dispersed SiO2@Au@TiO2(SAT) microspheres decorated with Au nanoparticles (AuNPs) were prepared and incorporated into the photoanode with an optimized concentration gradient-ascent. The effects of SAT microspheres and the gradient-ascent architecture on the light absorption and the photoelectric conversion efficiency (PCE) of the dye-sensitized solar cells (DSSCs) were investigated. Studies indicate that the introduction of SAT microspheres and the gradient-ascent architecture in the photoanode significantly enhance the light scattering and harvesting capability of the ...
