H2O2 Treatment of Electrochemically Deposited Cu2O Thin Films for Enhancing Optical Absorption
Cu2O is considered to be promising as an absorber layer material of solar cells, but its band gap (about 2.1 eV) is larger than the optimum one (about 1.5 eV). CuO has a smaller band gap of about 1.35 eV. Therefore, we attempted to oxidize Cu2O using H2O2 to increase oxygen ratio and decrease band g...
