Abstract
Abstract The photovoltaic cells (6) are retained and protected by a transparent elastomer layer (12) extruded when hot prior to vulcanization and applied against the cells with a slight pressure to cause it to go into the spaces between cells, and vulcanized by heating, for example at 110° C. or at 180° C., thanks to the presence of incorporated peroxides. Application in the production of electricity from solar energy.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
99 words
A method of manufacturing a panel of photovoltaic solar cells, said method comprising the following steps: disposing photovoltaic cells on a lower support plate and establishing electrical connections for these cells; disposing on the cells an upper transparent encapsulation layer to retain and protect these cells; the improvement comprising: disposing the encapsulation layer in the form of a soft layer of un-vulcanized elastomer; lightly applying on said un-vulcanized elastomer layer, a local progressive pressure to press it against the cells and the support plate to cause it to flow into the spaces between the cells; and vulcanizing this layer.
Claim 2
Independent Claim
99 words
A method of manufacturing a panel of photovoltaic solar cells, said method comprising the following steps: disposing photovoltaic cells on a lower support plate and establishing electrical connections for these cells; disposing on the cells an upper transparent encapsulation layer to retain and protect these cells; the improvement comprising: disposing the encapsulation layer in the form of a soft layer of un-vulcanized elastomer; lightly applying on said un-vulcanized elastomer layer, a local progressive pressure to press it against the cells and the support plate to cause it to flow into the spaces between the cells; and vulcanizing this layer.
Claim 3
Dependent Claim
24 words
The method as claimed in claim 1, wherein said layer of elastomer is pressed against the cells with the aid of a pressure roller.
Claim 4
Dependent Claim
15 words
The method as claimed in claim 1, wherein the encapsulation elastomer is a silicone elastomer.
Claim 5
Dependent Claim
31 words
The method as claimed in claim 3, wherein the encapsulation elastomer is a methylpolysiloxane of high molecular weight modified to allow polymerization when hot under the effect of an incorporated peroxide.
