ABSTRACT:
The invention involves (1) forming a transparent conductive film on an insulating transparent substrate, with the transparent conductive film defining a first electrode, (2) forming a non-crystalline semiconductor film on the transparent conductive film, (3) detecting any pinholes existing in the non-crystalline semiconductor film, (4) applying a laser beam in a reducing atmosphere through the detected pinholes to portions of the transparent conductive film located at portions of the pinholes, such that the portions of the transparent conductive film located at positions at which the pinholes are present are caused to have a high resistance by reduction, and (5) finally forming a metal film on the non-crystalline semiconductor film to define a second electrode.
