Abstract(in English) | Cu_2O is considered to be promising as an absorber layer material of solar cells, but its band gap is larger than the optimum one. Therefore, we attempted to oxidize Cu_2O using H_2O_2 to increase oxygen ratio and decrease band gap. Cu_2O thin films were deposited on indium-tin-oxide-coated glass from an aqueous solution containing CuSO_4, lactic acid and KOH by the galvanostatic electrochemical deposition at 40℃ with current density of -1mA/cm^2. Then, the as-prepared copper oxide thin film was dipped in H_2O_2 (30%) at 90℃ to oxidize for 10, 20 or 30 minutes. By the H_2O_2 treatment, the oxygen content was increased, and the band gap was decreased. |
