A solar module includes an encapsulant and solar cells in the encapsulant. The encapsulant includes a colored encapsulant on one side of the solar cells and a transparent encapsulant on the other side of the solar cells. An interface between the colored encapsulant and the transparent encapsulant is located more on the one side than a main surface of the other side of the solar cells and located more on the other side than a center in a thickness direction of the solar cells.

Solar module and method of manufacturing the same

A plurality of solar cells are sealed by an encapsulant between a first protective member and a second protective member. A fixing member fixes, among the plurality of solar cells, a first solar cell and a second solar cell that are adjacent to each other. The fixing member includes a release surface and a non-release surface that are oriented in opposite directions. The non-release surface has disposed thereon a first bonding region and a second bonding region that have adhesive strength, and a non-bonding region different from the first bonding region and the second bonding region.

Solar cell module including plurality of solar cells

A solar battery module and manufacturing method for a solar battery module having improved output are provided. The solar battery moduleis a transparent substrate, transparent resin layer, solar battery cell, colored resin layerand back sheetlaminated in this order. The light-receiving surfaceof the solar battery cellfaces the transparent resin layerside. The backsideof the solar battery cell faces the colored resin layer. The MFR [melt flow rate] of the transparent resin layeris lower than the MFR of the colored resin layer

Solar battery module and manufacturing method therefor

A solar cell module comprises a solar cell and sealing material provided on the rear surface side of the solar cell. The sealing material includes a colored layer that reflects light from the light-receiving surface side of the solar cell, and a transparent layer that is provided between the colored layer and the solar cell. The transparent layer has, in a space between adjacent solar cells, a side surface raised along the rear surface-side corner portion of the solar cell.

Solar cell module

A second protective member faces a first protective member. A bonding layer is disposed between the first and the second protective member. A solar cell includes a first main surface facing a side of the first protective member and a second main surface facing a side of the second protective member. A wiring member disposed on the second main surface. The bonding layer includes a first bonding layer disposed between the first protective member and the solar cell and made of a transparent resin a second bonding layer disposed between the second protective member and the solar cell and made of a colored resin, and a third bonding layer disposed between the second bonding layer and the solar cell and made of a transparent resin, and the second bonding layer is in contact with a main surface of the wiring member on a side of the second protective member.

A stack is obtained by stacking a glass plate, a first transparent resin sheet, a solar cell, a second transparent resin sheet, a colored resin sheet, and a first resin sheet. The stack is pressed under heat to fabricate a module including the glass plate, a first transparent bonding layer placed between the glass plate and the solar cell and formed of the first transparent resin sheet, a second transparent bonding layer placed between the first resin sheet and the solar cell and formed of the second transparent resin sheet, a colored bonding layer placed between the second transparent bonding layer and the first resin sheet and formed of the colored resin sheet, and the first resin sheet. A loss modulus of the colored resin sheet at a temperature of the pressing is higher than a loss modulus of the first transparent resin sheet at the temperature of the pressing.

Method of manufacturing solar cell module and solar cell module

In a solar module of the present invention, the ratio (TT) of a thickness (T) of a rear surface-side filling material layer at the end surface to a thickness (T) of a rear surface-side filling material layer in a region where a solar cell () is provided is set smaller than the ratio (TT) of a thickness (T) of a light receiving surface-side filling material layer at the end surface to a thickness (T) of the light receiving surface-side filling material layer in a region where the solar cell is provided. Consequently, entry of water into a filling material layer from the end surface of the filling material layer is effectively suppressed, and improved humidity resistance is achieved.
