Abstract
Abstract A solar cell planar array fabricated by a method from the solar cells to the mounting panel. An electrically insulative, thermally conductive wafer is soft-soldered to the surface of the metallic mounting panel. The top surface of the wafer bears spaced electrically insulative, thermally conductive prominences thereon. The solar cells are attached on top of the prominences.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
48 words
A solar cell array as in claim 1, wherein: said wafer is fabricated from beryllium oxide; said prominences and said coating on the bottom surface of said wafer comprise an inner layer of chromium and an outer layer of copper; and said soft solder is an indium solder.
Claim 2
Dependent Claim
135 words
A solar cell array for attachment to a metal panel comprising, in combination: a plurality of solar cells; a wafer-like member of beryllia, said beryllia being coated on its bottom surface with a metallic coating, the beryllia bearing on its top surface a plurality of individual metallic prominences isolated from each other, each solar cell being soldered on a different one of said prominences by means of a thermally conductive solder; and a layer of soft, solder having good thermal conductivity disposed between the bottom coating of said beryllia and said metal panel, by which means said beryllia coating and said panel adhere to each other, said array having a good thermally conductive path between the solar cells and the panel, and the beryllia insulating said path to electrically isolate the cells from the panel.
Claim 3
Dependent Claim
14 words
An array as in claim 3, wherein said thermally conductive solder is indium solder.
Claim 4
Dependent Claim
13 words
An array as in claim 3, wherein said solar cells are silicon cells.
Claim 5
Dependent Claim
27 words
An array as in claim 3, wherein said coating material and said prominences are formed from a first layer of chromium and a second layer of copper.
Claim 6
Dependent Claim
21 words
An array as in claim 6, wherein said metal panel is coated on its solder-contacting surface with a layer of copper.
