Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
105 words
An amorphous silicon semiconductor solar cell comprising one or more layers of amorphous silicon semiconductor material, a metal substrate on one side of and in contact with the amorphous silicon semiconductor material and a transparent electroconductive layer or Schottky barrier layer on the other side of and in contact with the silicon semiconductor material, characterized in that the surface of the metal substrate in contact with the amorphous silicon semiconductor is the surface of a two layer laminated metal or alloy film present upon an aluminum plate or film base and formed by means of an electroplating treatment on said aluminum plate or film base.
Claim 2
Dependent Claim
105 words
An amorphous silicon semiconductor solar cell comprising one or more layers of amorphous silicon semiconductor material, a metal substrate on one side of and in contact with the amorphous silicon semiconductor material and a transparent electroconductive layer or Schottky barrier layer on the other side of and in contact with the silicon semiconductor material, characterized in that the surface of the metal substrate in contact with the amorphous silicon semiconductor is the surface of a two layer laminated metal or alloy film present upon an aluminum plate or film base and formed by means of an electroplating treatment on said aluminum plate or film base.
