no. 1 approach

[0073] The transparent conductive film of the first embodiment includes at least a thin film substrate and a conductive layer, and further includes appropriately selected other members as necessary.

[0074] -Thin Film Substrate-

[0075] The film substrate is suitably selected without any limitation depending on the desired objective, but is preferably elastic, for example, a polymer film formed from: acrylic resins such as polycarbonate, polymethacrylate; Vinyl chloride resins such as polyvinyl chloride, vinyl chloride copolymers; thermoplastic resins such as polyarylates, polysulfones; polyethersulfones; polyimides; PET; PEN; fluororesins; phenoxy resins; polyolefin resins ; nylon; polystyrene resin; and ABS well known.

[0076] -conductive layer-

[0077] The conductive layer is properly selected according to the desired object without any limitation. It is preferred that the conductive layer is formed of a metal mesh, or contains a binder and conductive fibers.

no. 2 approach

[0132] In the second embodiment, the transparent conductive film contains at least a binder and a conductive material, and further contains appropriately selected other components as necessary.

[0133] The adhesive is appropriately selected depending on the intended purpose without any limitation, and the same adhesive as that in the transparent conductive film of the first embodiment can be employed.

[0134] The conductive material is properly selected according to the desired object without any limitation. For example, metal mesh, conductive fibers and the like are preferably used.

[0135] The metal mesh and conductive fibers are appropriately selected depending on the intended purpose without any limitation, and the same metal mesh and conductive fibers as those in the transparent conductive film of the first embodiment can be used.

[0208] -Manufacture of transparent conductive film 102-

[0209] According to the method described in Example 1 of JP-A No. 2006-24485, as a mesh formed by printing silver paste, a metal mesh was formed on a PET film substrate having a thickness of 50 μm. A screen printing mesh having a line width / grating pitch=195 μm / 5 μm and a pitch of 200 μm was used to form a metal mesh, thereby manufacturing the transparent conductive film 102 . The obtained transparent conductive film 102 was a grid-shaped metal mesh formed on a PET film substrate. As measured in the same manner as in Production Example 1, the surface resistance of the transparent conductive film on which the metal mesh was formed was 1.3Ω / sq, and the transparency of the transparent conductive film was 94%.

Abstract

A solar battery including a transparent conductive film; and a solar battery element, wherein the transparent conductive film is bonded to a surface of the solar battery element, and the transparent conductive film is electrically connected to the solar battery element.

Description

technical field [0001] The present invention relates to a solar cell including at least a solar cell element on which a transparent conductive film is bonded, and to a method for manufacturing the solar cell. Background technique [0002] For example, a crystalline silicon solar cell is formed in such a way that electrodes formed of silver or aluminum are patterned on the front and back surfaces of a silicon substrate in which a p-n junction is formed, and the electrodes are connected via copper wires called interconnects or the like, This forms a solar cell called a module. [0003] The series connection by interconnection is formed in such a manner that the solar cell element in which the electrodes are patterned on the silicon substrate in which the p-n junction is formed is dipped in a flux (flux) containing a catalyst, dried with warm air, and then Immerse in a solder bath, thereby coating the electrodes with solder. After the solder is applied, ultrasonic cleaning is...
