We report on the modification of structural, optical, electrical and dielectric properties of the electron transport layer (ETL) of Perovskite solar cell (PSC) i.e. Titanium dioxide (TiO2) by adding Magnesium (Mg), Zinc (Zn) and Silver (Ag) impurities in it through Sol-gel method. Modified parameters are studied with the help of X-Ray diffraction (XRD), UV-Visible (UV-Vis) spectroscopy, electrical and dielectric measurements by two probe method respectively. Fascinating results have been obtained in modified Mg-TiO2, Zn-TiO2 and Ag-TiO2 such as enhanced transmittance (T), reduction in refractive index (n), extinction coefficient (k), Urbach energy (EU), an increase in DC conductivity, dielectric constant (ϵ) and AC conductivity. The conductivity in modified TiO2 follows the order Ag-TiO2 > Zn-TiO2 > Mg-TiO2 > TiO2. The prepared samples are utilized in PSC device fabrication and the increased efficiency following the same order as conductivity suggests the idea of doping in ETL successful in solar cell application.
