The Smart Surface of TiO2 (SS-TiO2) is a self-cleaning thin film developed as a surface cleaning for solar cell applications. The SS-TiO2 is used to prevent dirt, debris or organic pollutants from contaminated onto glass wall, door, tiles or any surfaces. TiO2 is one of semiconductor which is widely used as a photocatalyst in since TiO2 can exhibit both photocatalytic and photo-induced superhydrophilicity properties.
