摘要

AbstractA Photoanode in dye sensitized solar cell is responsible for photoabsorption and conduction of the generated electrons for which TiO2is a highly employed material due to its non-toxic nature and low cost. This study reports a convenient and facile method to prepare un-doped and magnesium (Mg) doped TiO2thin films using Aerosol assisted Chemical Vapor deposition on Indium doped Tin oxide substrates. The as prepared films were subjected to morphological and structural characterizations as well as the optical absorption, band gap and surface area measurements of films. The studies indicated that Mg substituted Ti in the TiO2lattice and formed new energy levels which decreased the band gap of the doped films. Moreover, increasing the concentration of Mg shifted the optical absorption of the films from ultra-violet region to the visible region. The IV measurements of the DSSCs fabricated using 2?mol% Mg doped TiO2film, N719 dye, I?/I3?redox electrolyte and platinum sputtered on ITO counter electrode, revealed approximately twofold increase in overall efficiency of DSSCs as compared to undoped TiO2based DSSC. The increase in Vocand Jsc, as well as the efficiency of 6.1%, is an indication that 2?mol% Mg doped TiO2film is a potential candidate as a photoanode material in DSSC.Highlights?Mg doped TiO2thin films coated using aerosol assisted chemical vapor deposition.?Effective enhancement in TiO2light absorption towards visible region.?Reduced bandgap of TiO2using Mg doping and enhanced dye Adsorption.?Porous thin films without compromising the surface area of the films.?Doping and controlled-deposition enhanced the performance of N719 dye based DSSCs.]]>
