Abstract

A method for manufacturing a thin-film solar cell module includes a rear surface electrode layer deposition step for depositing a rear surface electrode layer on a substrate, an alkali metal adding step for adding an alkali metal to the rear surface electrode layer, a light absorbing layer deposition step for depositing a light absorbing layer on the rear surface electrode layer, a division groove forming step for forming a division groove that divides the light absorbing layer and exposing a front surface of the rear surface electrode layer in the division groove, an alloying step for alloying the rear surface electrode layer and the alkali metal on the front surface of the rear surface electrode layer exposed in the division groove, and a transparent conductive film deposition step for depositing a transparent conductive film on the light absorbing layer and in the division groove.
