Abstract
An amorphous silicon solar cell comprising a glass substrate, a transparent conductive film formed on the glass substrate on one side thereof and having micro-columns or fine crystals irregularly formed on the other side, a plurality of amorphous silicon layers superposed on said other side of the conductive film, and a metal electrode formed on the superposed silicon layer. At the interface between the transparent conductive film and the amorphous silicon layer is formed an intermediate layer in which both materials of the conductive film and the silicon layer are mixed. The intermediate layer has a refractive index between the conductive film and the silicon layer. The glass substrate may be substituted with a metal substrate, in which case the plurality of silicon layers are formed directly on the metal substrate, on which the transparent conductive film having an irregular surface on the side opposite to the side where the silicon layers are formed and a metal electrode are formed in this order.
