Abstract : Dye-sensitized solar cells (DSSCs) are third-generation solar cells, which overcome the Shockley—Queisser limit of power efficiency for single band gap solar cells. The dye-sensitized nanocrystalline semiconductor electrode is the heart of the device and plays an important role in determining the DSSC performance. DSSCs employing rutile titanium dioxide (TiO2) generally suffer from a lower conduction band compared to anatase, leading to lower open-circuit voltage. In DSSC, photoanode is one of the components which decide the efficiency of the cell. In order to improve the efficiency by reducing charge recombination and modifying electronic structures, nanostructures of TiO2 and doped TiO2 are tried. The more effective way of modifying electronic properties of TiO2 is by doping with alkaline earth metals, metalloids, nonmetals, transition metals, posttransition metals, lanthanides, Co- and tri-doped with other materials
