Mesoporous Titania-Vertical Nanorod Films With Interfacial Engineering For High Performance Dye-Sensitized Solar Cells

Mesoporous Titania-Vertical Nanorod Films With Interfacial Engineering For High Performance Dye-Sensitized Solar Cells

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...
