| Abstract: | This review focuses on recent developments in the nanostructured SnO2 photoanodes for dye-sensitized solar cells (DSSCs) applications. Carefully designed and fabricated nanostructured SnO2 films are advantageous for effective improvement in performance of DSSCs. Nanocrystals can offer a large surface area for dye adsorption; nanowires are able to provide a direct transfer pathway for the rapid collection of photogenerated electrons; the mesoporous, monodisperse beads with a submicrometer-sized diameter ensure a large specific surface area for dye adsorption and simultaneously promote light scattering; the surface modification of SnO2 by other oxides may improve the photovoltage and photocurrent, hence resulting in the higher power conversion efficiency of SnO2-based DSSCs. |
