Claim:
1. A method for manufacturing a thin-film solar cell module, comprising: 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.
