Abstract:
An improved method of manufacturing a solar cell receiver plate of a concentrator photovoltaic array comprising the following steps:(a) taking a secondary aluminum substrate having a top surface and having a length X and a width Y and covering said top surface first with a first layer of adhesive; following this a dielectric layer having a top surface is placed on said first layer of adhesive;(b) next a second layer of adhesive is applied to said top surface of said dielectric layer and following this a copper sheet is placed on said second layer of adhesive to form a laminated first assembly;(c) applying a photo resist coating to the top surface of said laminated first assembly and forming strips, each having its own linear electrical circuit, in said top surface of said first assembly by chemically etching away all of the unwanted copper in said top surface of said first assembly; said strips having a length substantially equal to X and a width Y/n where n is greater than 6;(d) segmenting said strips from said laminated first assembly;(e) fastening two or more of said strips to the top surface of a primary aluminum substrate to form a receiver plate for a concentrator photovoltaic array;(f) mounting a plurality of solar cells on the electrical circuit of each of said strips; and(g) electrically connecting the electrical circuits of said strips together.
