Abstract

Y2O3:(Eu3+,Gd3+) is introduced into a dye-sensitized solar cell. As a luminescence medium, Y2O3:(Eu3+,Gd3+) improves light harvest via conversion luminescence process and increases photocurrent; as a p-type dopant, Y2O3:(Eu3+,Gd3+) elevates photovoltage. The cell's light-to-electric energy conversion efficiency enhances 18.6% compared to the cell without Y2O3:(Eu3+,Gd3+) doping.
