Abstract

In the present work, Porous Yttrium doped TiO2 nanoparticles under different doping concentrations have been synthesized via simple solvothermal route using glycerol as both solvent and chelating agent. Morphology and distribution of Yttrium in the TiO2 crystal lattice were analyzed through scanning electron microscopy (SEM) combined with elemental mapping using energy dispersive X-ray spectroscopy (EDX).Uniform size of the synthesized nanoparticles could be observed via SEM results.  X-Ray Diffraction, RAMAN spectroscopy,UV-Vis and PL spectroscopic studies have done to investigate the influence of Yttrium dopant on its crystal structure and optical properties to exploit them as Electron Transport layer in perovskite solar cells. From the results of XRD and RAMAN, after incorporating yttrium into TiO2 lattice there is no significant change observed in its crystal structure which also confirms the formation of anatase phase and from UV-Vis spectrosopy, red shift in the absorption edge could be observed for 2 mol% Y doped TiO2.From the results of basic characterization studies, glycerol mediated yttrium doped TiO2 can be used as an electron transport layer for perovskite based solar cells.
