Title:
THIN-FILM SOLAR CELL MODULE, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2013/077431
Kind Code:
A1
Abstract:
This method for producing a thin-film solar cell module involves: a rear-surface electrode layer formation step in which a rear-surface electrode layer is formed on a substrate; an alkali metal addition step in which an alkali metal is added to the rear-surface electrode layer; a light-absorbing layer formation step in which a light-absorbing layer is formed on the rear-surface electrode layer; a dividing groove formation step in which a dividing groove for dividing the light-absorbing layer is formed and the surface of the rear-surface electrode layer is exposed within the dividing groove; an alloying step in which the rear-surface electrode layer and the alkali metal are alloyed at the surface of the rear-surface electrode layer exposed within the dividing groove; and a transparent conductive film formation step in which a transparent conductive film is formed on the light-absorbing layer within the dividing groove.
