摘要：

Working electrode (WE) fabrication offers significant challenges in terms of achieving high-efficiency dye-sensitized solar cells (DSCs). We have combined the beneficial effects of vertical nanorods grown on conducting glass substrate for charge transport and mesoporous particles for dye loading and have achieved a high photoconversion efficiency of (eta) > 11% with an internal quantum efficiency of similar to 93% in electrode films of thickness similar to 7 +/- 0.5 mu m. Controlling the interface between the vertical nanorods and the mesoporous film is a crucial step in attaining high.. We identify three parameters, viz., large surface area of nanoparticles, increased light scattering of the nanorod-nanoparticle layer, and superior charge transport of nanorods, that simultaneously contribute to the improved photovoltaic performance of the WE developed.
