PHOTOELECTRIC CONVERSION APPARATUS AND METHOD FOR MANUFACTURING THE SAME |
摘要 |
An object of the present invention is to provide a photovoltaic device and a process for producing such a photovoltaic device that enable a stable, high photovoltaic conversion efficiency to be achieved by using a transparent electrode having an optimal relationship between the resistivity and the transmittance. At least one transparent electrode (12, 16) is either a ZnO layer containing no Ga or a Ga-doped ZnO layer in which the quantity of added Ga is not more than 5 atomic % relative to the Zn within the ZnO layer, and the ZnO layer is formed by a sputtering method using a rare gas containing added oxygen as the sputtering gas, wherein the quantity of oxygen added to the sputtering gas is not less than 0.1% by volume and not more than 5% by volume relative to the combined volume of the oxygen and the rare gas. |
