Antireflective Self-Cleaning TiO2 Coatings for Solar Energy Harvesting Applications

Titanium(IV) oxide (TiO 2 , titania) is well-known for its excellent photocatalytic properties, wide bandgap, chemical resistance, and photostability. Nanostructured TiO extensively utilized in various electronic energy-related applications such as resistive switching memory devices, flat panel displays, photodiodes, solar water-splitting, photocatalysis, cells. This article presents recent advances the design nanostructuring of -containing antireflective self-cleaning coatings In particular, energy harvesting efficiency a cell greatly diminished by surface reflections deposition environmental contaminants over time. not only minimize reflection through graded transition refractive index but simultaneously improve device’s ability to self-clean photocatalytically degrade pollutants. Thus, novel approaches achieve higher stability with pristine nanocomposite are highlighted herein. The results compared discussed emphasize key research development shortfalls commercialization perspective considered guide future research.
