TiO2 is an attractive material for dye sensitized solar cells (DSSC) because it is inexpensive and non-toxic as compared to the Si-based solar cells. Plasma spraying is an ideal method to produce TiO2 based DSCC due to its high deposition rate and ease of scale-up. In the present study, TiO2-carbon nanotube (CNT) based composite is explored as DSCC material. It has been shown in the literature that carbon nanotubes improve the conversion efficiency of DSSC in many ways. This study investigates the role of CNT addition in terms of phase transformation from anatase to rutile, microstructural properties and photocatalytic properties. TiO2 and TiO2-CNT coatings are prepared by plasma spraying on the stainless steel and FTO glasses. These composite coatings are characterized by X-ray diffraction and scanning electron microscopy. Photocatalytic properties are also measured by MB solution method.
