First, first cell wiring members from the first solar cell and second cell wiring members from the second solar cell are sandwiched between a wiring member film and a second bridge wiring member. Subsequently, the first cell wiring members and the second cell wiring members are connected to the second bridge wiring member by applying heat to at least the first cell wiring members, the second cell wiring members, and the second bridge wiring member by induction heating.

Solar cell module manufacturing method and solar cell module

A solar cell module including: a solar cell; a first protection member provided on the light receiving surface side of the solar cell; a second protection member provided on the rear surface side of the solar cell; an encapsulant layer, including a first encapsulant layer disposed between the solar cell and the first protection member, and a second encapsulant layer disposed between the solar cell and the second protection member, which seals the solar cell; and a wavelength conversion substance, contained in at least the first encapsulant layer, which absorbs light having a specified wavelength, and converts the wavelength. The concentration of the wavelength conversion substance is higher in the first encapsulant layer than in the second encapsulant layer, and a resin constituting the second encapsulant layer has a smaller diffusion coefficient of the wavelength conversion substance than the diffusion coefficient of a resin constituting the first encapsulant layer.

Solar cell module

This solar cell module is provided with: a plurality of solar cells; and a tab, which electrically connects the solar cells, and which has recesses and projections on the surface thereof. The tab has height of the recesses and the projections smaller in the peripheral region of each of the solar cells, compared with that in other regions of each of the solar cells.

Disclosed is a method for manufacturing a solar cell module (), said method being provided with: a first step for a first step for manufacturing a laminated body by sequentially stacking and thermocompression-bonding a solar cell (), sealing material (), first protection member () and second protection member (); and a second step, which is a step of heating the solar cell () of the laminated body, and in which the sealing material () is indirectly heated due to a temperature increase of the solar cell ().

Solar cell module manufacturing method and solar cell module manufacturing apparatus

Provided is a solar cell module wherein solar cells and a sealing material, which is sealing the solar cells, are not easily peeled from each other. A solar cell module is provided with solar cells, a wiring material, and a sealing material. Each of the solar cells has first and second main surfaces. The wiring material is electrically connected to each of the solar cells on the first main surface. The sealing material seals the solar cells. The sealing material has a first sealing section and a second sealing section. The first sealing section contains a non-bridging resin. The first sealing section is positioned on the first main surface side of the solar cells. The second sealing section contains a bridging resin and pigment. The second sealing section is positioned on the second main surface side of the solar cells.

A solar cell module includes an encapsulant and a solar cell in the encapsulant. The encapsulant includes a light-receiving side encapsulant at a light-receiving surface side of the solar cell, and a colored rear side encapsulant at a rear surface side of the solar cell. The rear side encapsulant contains an ethylene-vinyl acetate copolymer. An interface between the rear side encapsulant and the light-receiving side encapsulant is in contact with a side surface of the solar cell. In a part of an area where no solar cell is provided, the rear side encapsulant bulges to the light-receiving surface side.
