Abstract
Abstract A solar cell comprising two electrodes, a collector grid, a copper sulphide layer and a cadmium sulphide layer, wherein the two electrodes are constituted by a single conductive film divided into two parts separated by an insulating material, said sulphide layers being deposited on one of said parts and surmounted by said collector grid which is electrically connected to said other part of the conductive film.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
110 words
A PROCESS FOR MANUFACTURING A SOLAR CELL COMPRISING TWO ELECTRODES, A COLLECTOR GRID, A COPPER SULPHIDE LAYER AND A CADMIUM SULPHIDE LAYER, SAID PROCESS COMPRISING DEPOSITING ON AN INSULATING SUPPORT A CONDUCTIVE LAYER OR FILM IN TWO DISTINCT AREAS SEPARATED BY A ZONE IN WHICH THE INSULATING SHEET REMAINS BARE, SUCCESSIVELY DEPOSITING ON ONE OF SAID AREAS A LAYER OF CDS AND A LAYER OF CU2S, FORMING A MASK ON THE LAYER OF CU2S, ELECTROLYTICALLY DEPOSITING A METAL ON SAID MASKED LAYER OF CU2S BY USING SAID CONDUCTIVE LAYER DEPOSITED ON SAID FIRST AREA AS A CATHODE FOR AN ELECTROLYSIS DEVICE AND REMOVING THE MASK ON SAID LAYER OF CU2S.
Claim 2
Dependent Claim
