Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
91 words
A method of making a module of solar cells having a transparent cover comprising the steps of forming a plurality of depressions in said transparent cover, placing a solar cell in each of said depressions so that the front surfaces of the solar cells which are to face a light source contact the bottoms of said depressions, positioning a back cover over said solar cells in contact with the back surfaces thereof opposite said front surfaces, and electrically connecting said solar cells while securing said transparent cover to said back cover.
Claim 2
Independent Claim
91 words
A method of making a module of solar cells having a transparent cover comprising the steps of forming a plurality of depressions in said transparent cover, placing a solar cell in each of said depressions so that the front surfaces of the solar cells which are to face a light source contact the bottoms of said depressions, positioning a back cover over said solar cells in contact with the back surfaces thereof opposite said front surfaces, and electrically connecting said solar cells while securing said transparent cover to said back cover.
Claim 3
Dependent Claim
31 words
A method of making a module of solar cells as claimed in claim 1 wherein the transparent cover is embossed to form a plurality of depressions in an array of rows.
Claim 4
Dependent Claim
92 words
A method of making a module of solar cells as claimed in claim 2 wherein each solar cell has both positive and negative electrical contacts on said back surface thereof opposite said front surface including the steps of forming a plurality of metal films on said back cover prior to positioning the same over said solar cells, and positioning said back cover over said solar cells so that said metal films electrically connect the contacts on all the cells in one row to the contacts on the cells in an adjacent row.
Claim 5
Dependent Claim
38 words
A method of making a module of solar cells as claimed in claim 3 including the steps of laminating said transparent cover to said back cover while simultaneously forming electrical connections between adjacent solar cells by compression bonding.
Claim 6
Independent Claim
137 words
A method of making a module of solar cells wherein each solar cell has one contact on the front surface thereof and another contact on the back surface thereof comprising the steps of forming a plurality of depressions in a transparent cover, forming a first metal film in each depression, placing a solar cell in each of said depressions so that the front surface of the solar cell which is to receive light faces the bottom of said depression and contacts said first metal film, forming a plurality of second metal films on said back cover, and positioning said back cover over said solar cells so that said second metal films electrically connect the first metal films on all the depressions in one row to the back surface contacts on all the cells in an adjacent row.
Claim 7
Independent Claim
137 words
A method of making a module of solar cells wherein each solar cell has one contact on the front surface thereof and another contact on the back surface thereof comprising the steps of forming a plurality of depressions in a transparent cover, forming a first metal film in each depression, placing a solar cell in each of said depressions so that the front surface of the solar cell which is to receive light faces the bottom of said depression and contacts said first metal film, forming a plurality of second metal films on said back cover, and positioning said back cover over said solar cells so that said second metal films electrically connect the first metal films on all the depressions in one row to the back surface contacts on all the cells in an adjacent row.
Claim 8
Dependent Claim
37 words
A method of making a module of solar cells as claimed in claim 5 including the steps of laminating said transparent cover to said back cover while simultaneously forming electrical connections between adjacent solar cells by sintering.
