摘要:
A solar-cell module having a photovoltaic device, a reinforcing sheet for reinforcing the photovoltaic device and a covering material which seals the photovoltaic device on the reinforcing sheet is bent at a region between the border of the photovoltaic device and the outer edge of the reinforcing sheet, where the reinforcing sheet is covered with the covering material at the part extending from the border of the photovoltaic device up to the bent portion closest thereto, or the covering material is, at the margin thereof, made to have a thickness cross-sectionally smaller as it extends farther from the border of the photovoltaic device, provided that the reinforcing sheet is not covered at the outward margin thereof with the covering material. The covering material which covers the photovoltaic device of the solar-cell module is peel-resistant.

A solar cell module comprises a photovoltaic device having a flexible substrate. The photovoltaic device has a strain at least partly in the planar direction of the flexible substrate, and the strain is not greater than a critical value at which the photovoltaic device cracks. The solar cell module may further comprise a strain holding means for holding the strain. A deformable region where the photovoltaic device can be deformed when a region embracing the photovoltaic device is worked is defined so that a great variety of solar cell modules having a high reliability, also taking account of manufacture, can be designed with good efficiency.

A solar cell module comprises a front surface member disposed on a front surface side of a photovoltaic element having at least a semiconductor photoactive layer on a flexible substrate, a back surface member disposed on a back surface side of the photovoltaic element, and a sealing material interposed therebetween. The flexible substrate of the photovoltaic element has a plurality of substantially parallel surface grooves on a surface thereof at the semiconductor photoactive layer side of the flexible substrate. At least one portion of the solar cell module is processed to deform in such a direction that strain generated in a substantially parallel direction to the surface grooves is applied to the photovoltaic element. In this way, a solar cell module can be subjected to deformation-processing that prevents, to the extent possible, cracks in the semiconductor photoactive layer of the photovoltaic elements; in other words, deformation-processing can be achieved without influencing electrical characteristics. A method of producing such a solar cell module is also disclosed.

A solar-cell module is provided which comprises a photovoltaic device sealed on a reinforcing sheet with a filler material, wherein the reinforcing sheet has unevenness formed by plastic deformation, on its surface at least on the side of the photovoltaic device and at least partly on the surface, and a space defined by the unevenness and the photovoltaic device is filled with the filler material. The solar-cell module is produced by a process comprising the steps of superposing at least a thermoplastic-resin sheet member and a photovoltaic device on a reinforcing sheet having unevenness on its surface, and heating the thermoplastic-resin sheet member, the photovoltaic device and the reinforcing sheet while removing air from a space between the reinforcing sheet and the thermoplastic-resin sheet member and a space between the thermoplastic resin sheet member and the photovoltaic device, to bring them into close contact to fix to each other.A solar-cell module can thereby be provided which has no trapped air portions that may be formed between the filler material and the reinforcing sheet when the photovoltaic device is sealed with the filler material and fixed onto the reinforcing sheet to produce the solar-cell module.
