Abstract

The present disclosure relates to a method to enhance the efficiency and reduce interfacial charge transfer resistance in dye sensitized solar cell (DSSC) and a perovskite solar cell (PSC) by fabricating with Mg and La doped photoanodes. Mg and La co-doped into TiO2 has shown more than 20% efficiency than pristine TiO2 and more than 5% higher efficiency than the single doping of 1% La and Mg in TiO2 cells. Thus, the present disclosure relates to an improved photoanode material to be used in solar cells.
