PROBLEM TO BE SOLVED: To provide a method for manufacturing a solar battery in which the time for manufacturing a solar battery is shortened by shortening the time for formation of a thin film of silicate such as blue plate glass.SOLUTION: A method for manufacturing a solar battery comprises the steps of: (S1-S3) preparing a sintered compact produced by sintering blue plate glass powder; and (S4) forming a thin film of the sintered compact on a surface of an alkali metal-free ceramic substrate. The film formation step is performed by sputtering, in which the sintered compact of the blue plate glass powder is used as a sputtering target, so that a film formation time in the case of using a substrate according to the present invention can be made shorter than that in film formation by sputtering while using a substrate of blue plate glass not-yet-powdered nor sintered as a sputtering target as long as the film thickness is common to the substrates. After stacking, over a surface of the thin film of the sintered compact, a backside electrode layer, a light absorption layer including a chalcopyrite compound, and a surface electrode layer are laminated in turn to manufacture a solar battery, thereby shortening the manufacturing time of the solar battery. |
