Here in, we report a physical novel method as charge injection assisted sintering process in the field of dye sensitized solar cell. Charge injection within sintering process can decrease TiO₂ nanoparticle aggregation and increase effective surface area very well which provide more space for dye settlement. Obviously, FESEM imaging exhibits surface area increased in nanoparticle matrix. Current and voltage characteristic shows that charge injection could enhance current density 31%. In order to survey the effect of charge injection on dye loading condition, absorption spectroscopy has been used. Spectroscopy analysis reveals that proposed method could increase dye capacity 48% in nanoporous photoanode.
