A photovoltaic module capable of suppressing separation of a tab electrode can be obtained. The photovoltaic module includes a plurality of semiconductor layers including a photoelectric conversion layer, a plurality of photovoltaic elements including a finger electrode for collecting generated currents, formed on the semiconductor layers on a side of a light receiving surface, and a tab electrode for electrically connecting the plurality of photovoltaic elements, in which the tab electrode is electrically connected to the finger electrode in a region corresponding to a power generation region of the photovoltaic element and bonded on the light receiving surface through an insulating bonding material.

Photovoltaic module

A solar battery module comprises a substrate over a surface of which a solar battery unit is formed, and a resin structure which contacts the substrate and which covers a part of a side surface and a back surface of the substrate. The resin structure comprises a resin and a buffer material having a lower thermal expansion coefficient than the resin, and a mixture ratio of the buffer material with respect to the resin is reduced as a distance from the substrate is increased.

Solar battery module and forming method thereof

A method for manufacturing a solar cell modulecomprises the steps of exposing a part of the metal electrode layerin a pinhole PH' which is formed in the resin layerby applying a reverse voltage across the transparent electrode layerand the metal electrode layerin the reverse voltage repair process and removing the part of the metal electrode layerby etching the part of the metal electrode layerusing the resin layeras a mask.

Method for manufacturing solar cell module

A double-side light receiving solar cell in a planer regular hexagon shape and having first electrodes on both surfaces are divided into four pieces by a line A-A' connecting two opposing apexes and by a line B-B&#x2032; perpendicular to the line A-A&#x2032; and connecting center points on two opposing sides. By matching oblique lines of two divided pieces without misalignment and with respective surfaces in an inversed state, the first electrodes on the same side of the two divided pieces align along the same single straight line. Then, the first electrodes that are on the same side are connected with a first inter connecter, thereby constructing a unit having a rectangular outline. Units thus constructed are arranged so that relevant sides match without misalignment. By handling on a unit basis as described above, it is possible to facilitate an arrangement of the cells and an electricity connection work.

Manufacturing method of solar cell module, and solar cell and solar cell module

A solar battery cell having a hexagonal shape is divided into four at a straight line connecting between opposed apexes and a straight line connecting between middle points of opposed sides. Two of the divided cells are arranged without being turned upside down such that oblique sides thereof oppose each other; thus, a substantially rectangular-shaped unit is configured. In adjoining two units, an interconnector is routed from a front surface of one of the units to a back surface of the other unit. Thus, the two units are electrically connected to each other through the interconnector. Hence, it is unnecessary to route an interconnector from a front surface of one divided cell to a back surface of another divided cell at a portion where oblique sides of the divided cells oppose each other; therefore, it is unnecessary to secure a large clearance at the portion.

The second soften temperature is higher than the first soften temperature.
