One Pot Synthesis of Multi-functional Tin Oxide Nanostructures for High Efficiency Dye-sensitized Solar Cells

Photoanode plays a key role in dye sensitized solar cells (DSSCs) as a scaffold for dye molecules, transport medium for photogenerated electrons, and scatters light for improved absorption. Herein, tin oxide nanostructures unifying the above three characteristics were optimized by a hydrothermal pro...
