Abstract
Abstract A basic photovoltaic stack is constituted by a semiconducting layer interposed between a layer forming an ohmic contact and a layer forming a Schottky contact. A second photovoltaic stack having the same structure as the basic stack is formed on this latter and includes one of the layers forming an ohmic or Schottky contact. The layer or layers forming an ohmic contact are connected together so as to constitute a first output terminal of the photovoltaic generator. The layer or layers forming a Schottky contact are connected together so as to constitute a second output terminal of the generator.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
111 words
A photovoltaic generator comprising a basic photovoltaic stack having a structure consisting of a semiconducting layer interposed between a layer forming an ohmic contact and a layer forming a Schottky-type contact, wherein at least one additional photovoltaic stack having a structure which is identical with that of the basic stack is formed on said basic stack and includes one of the layers forming an ohmic or Schottky contact, the layer or layers forming an ohmic contact being interconnected so as to constitute a first output terminal of the generator and the layer or layers forming a Schottky contact being interconnected so as to constitute a secnd output terminal of the terminal.
