Abstract
Abstract A solar-cell module and a process for producing the same are disclosed. The solar-cell module comprising a solar-cell panel comprising a light-transmitting plate having a first surface and a second surface opposite to the first surface, and solar-cell elements disposed on the second surface; a frame disposed around the entire periphery of the solar-cell panel and having a flange on which the solar-cell panel is supported on the second surface while the first surface is free; and an adhesive layer disposed between the second surface of the solar-cell panel and the flange of the frame, wherein the adhesive layer comprises a reactive hot-melt adhesive comprising as a major component a urethane prepolymer obtained by reacting a polyhydroxy compound with an excess amount of a polyisocyanate compound. The solar-cell module can be produced easily and is excellent in quality and reliability.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
114 words
A solar-cell module comprising: a solar-cell panel comprising a light-transmitting plate having a first surface and a second surface opposite to the first surface, and solar-cell elements disposed on the second surface, a frame disposed around the entire periphery of the solar-cell panel and having a flange on which the solar-cell panel is supported on the second surface while the first surface is free, and an adhesive layer disposed between the second surface of the solar-cell panel and the flange of the frame, wherein said adhesive layer comprises a reactive hot-melt adhesive comprising as a major component a urethane prepolymer obtained by reacting a polyhydroxy compound with an excess amount of a polyisocyanate compound.
Claim 2
Dependent Claim
114 words
A solar-cell module comprising: a solar-cell panel comprising a light-transmitting plate having a first surface and a second surface opposite to the first surface, and solar-cell elements disposed on the second surface, a frame disposed around the entire periphery of the solar-cell panel and having a flange on which the solar-cell panel is supported on the second surface while the first surface is free, and an adhesive layer disposed between the second surface of the solar-cell panel and the flange of the frame, wherein said adhesive layer comprises a reactive hot-melt adhesive comprising as a major component a urethane prepolymer obtained by reacting a polyhydroxy compound with an excess amount of a polyisocyanate compound.
Claim 3
Dependent Claim
16 words
The solar-cell module of claim 1, wherein said reactive hot-melt adhesive further comprises a thermoplastic polymer.
Claim 4
Dependent Claim
33 words
The solar-cell module of claim 1, wherein said polyhydroxy compound is one or more compounds selected from polyoxyalkylene ether polyols, polyester polyols, acrylic polyols, rubber polyols including polybutadiene polyols, and castor oil derivatives.
Claim 5
Dependent Claim
45 words
The solar-cell module of claim 1, wherein said polyisocyanate compound is one or more compounds selected from diphenylmethane diisocyanate, dimethyldiphenylmethane diisocyanate, naphthalene diisocyanate, isophorone diisocyanate, cyclohexylmethane diisocyanate, tolylene diisocyanate, tetramethylene diisocyanate, hexamethylene diisocyanate, xylene diisocyanate, p-phenylene diisocyanate, trimethylolpropane adducts of polyisocyanates, and polymers of polyisocyanates.
Claim 6
Dependent Claim
142 words
A process for producing a solar-cell module comprising the steps of: providing a solar-cell panel comprising a light-transmitting plate having a first surface and a second surface opposite to the first surface, and solar-cell elements disposed on the second surface, and a frame capable of being disposed around the entire periphery of the solar-cell panel and having a flange for supporting thereon the second surface of the solar-cell panel, applying onto the flange of the frame a reactive hot-melt adhesive comprising as a major component a urethane prepolymer obtained by reacting a polyhydroxy compound with an excess of a polyisocyanate compound to form an adhesive layer, and placing the solar-cell panel onto the adhesive layer on the flange in such a manner that the second surface contacts the adhesive layer, thereby bonding the solar-cell panel with the frame via the adhesive layer.
Claim 7
Dependent Claim
142 words

Claim 8
Dependent Claim
15 words
The process of claim 5, wherein said reactive hot-melt adhesive further comprises a thermoplastic polymer.
Claim 9
Dependent Claim
32 words
The process of claim 5, wherein said polyhydroxy compound is one or more compounds selected from polyoxyalkylene ether polyols, polyester polyols, acrylic polyols, rubber polyols including polybutadiene polyols, and castor oil derivatives.
Claim 10
Dependent Claim
44 words
