    摘要： The invention relates to a solar module with improved bonding. The solar module (100) comprises a front encapsulant layer (104), solar cells (106), a middle encapsulant layer (108), a back contact foil (210b) with a patterned copper pattern (210b) thereon, and a back encapsulant layer (112). Inventors found that, when producing such a solar module, the bonding between the middle encapsulant layer and the copper side of the back contact foil was insufficient. A solution is found in providing cut-outs in the back contact foil through which the back encapsulant layer can bond to the middle encapsulant layer and/or the solar cells.

    摘要： The present invention relates a photovoltaic module comprising a protective front layer element, an encapsulation layer element, a photovoltaic cell element and a protective back layer element, whereby at least one of the protective elements comprises glass; wherein the encapsulation layer element comprises a polymer composition (I) comprising at least the following components: (A) 97.00 to 99.99 wt.-% based on the overall weight of the polymer composition (I) of a polymer selected from an ethylene-vinylacetate copolymer, a polyolefin elastomer or a polymer of ethylene (a) selected from (a1) a copolymer of ethylene which bears functional groups containing units; (a2) a copolymer of ethylene comprising one or more polar comonomer unit(s) selected from (C1-C6)-alkyl acrylate or (C1-C6)-alkyl (C1-C6)-alkyl acrylate comonomer units, and optionally bears functional groups containing units different from said polar comonomer unit(s); (a3) a copolymer of ethylene comprising one or more alpha-olefin comonomer unit(s); and optionally bears functional groups containing units different from said polar comonomer unit(s) of polymer (a2); or mixtures thereof; and (b) silane group(s) containing units; (B) 0.01 to 3.00 wt.-% based on the overall weight of the polymer composition (I) of a compound according to Formula (I); wherein; R1, R1′, R2 and R2′ are each independently selected from the group consisting of hydrogen, n-alkyl, iso-alkyl, alkoxy, cycloalkyl, alkenyl, halogen and mixtures thereof; X is selected from the group consisting of primary amines, secondary amines, tertiary amines, hydrogen, alkyl, alkenyl and mixtures thereof. Furthermore, the present invention refers to the use of an encapsulation layer element comprising polymer composition (I) according to the invention for increasing the Pmax determined after 96 h according to IEC 60904, by applying the foil method with a temperature of 85° C. and relative humidity of 60% and a potential difference of 1500 V, of a photovoltaic module comprising besides the encapsulation layer element a protective front layer element, a photovoltaic cell element and a protective back element, whereby at least one of the protective elements comprises glass.

    摘要： A system includes first, second and third photovoltaic modules on a rood. Each module includes an upper edge, a lower edge and at least one solar cell. Lower edges of the cells of the first and second modules are offset from lower edges of the first and second modules. Upper edge of the cell of the second module is offset from the upper edge of the second module. The upper edge of the cell of the third module is offset from the upper edge of the third module. The first module overlays the second module. The lower edge of the cell of the first module is substantially aligned with the upper edge of the cell of the second module. The second module overlays the third module. The lower edge of the cell of the second module is substantially aligned with the upper edge of the cell of the third module.

    摘要： A panel connected body includes a plurality of flat panels arranged in a matrix of m rows and n columns, where m≥3 and n≥3; and a plurality of row-direction connection portions and column-direction connection portions which connect together panels that are adjacent in a row direction and column direction, respectively. A first type row satisfying relationships D1≥2L and Dy≥Dy−1−2L and a second type row satisfying relationships Dn≥2L and Dy≥Dy+1+2L are alternately included, where Dy is a length along the column direction of the column-direction connection portions in a y-th column, and L is a thickness of the panels. The relationship E≤WC−L is satisfied, where WC is a length along the column direction of the panels and E is a length along the column direction of the row-direction connection portions.
