Tin Oxide as a Photoanode for Dye-sensitised Solar Cells: Current Progress and Future Challenges

Tin oxide (SnO2) is a candidate for applications requiring high electrical conductivity and optical transparency, such as a photoanode in dye-sensitised solar cells (DSSCs), due to its higher electron mobility and wider optical transparency than many other metal oxide semiconductors (MOS), such as T...
