Embodiment Construction

[0017] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0018] A lightweight thin-film solar cell module and a manufacturing method thereof, comprising the following process steps:

[0019] ① Use toughened glass or semi-tempered glass instead of ordinary float glass as the substrate of thin-film solar cells to ensure the mechanical strength of the module and reduce the weight of the module; ② Use reflective packaging materials instead of titanium dioxide back reflection layer or metal back reflection layer and transparent packaging materials to reduce the production cost of components and simplify the production process; ③A polymer composite film containing a metal layer is used as the backsheet of thin-film solar cells to prevent water vapor intrusion and reduce the weight of components; ④The electrodes at the junction box are drawn out The wire is pasted with insulating tape to prevent the electrod...

Abstract

The invention, which belongs to the solar cell device preparation field, relates to a lightweight film solar module and a manufacturing method thereof. A technology scheme is characterized in that: (1) toughened glasses or half toughened glasses are used to substitute common float glasses as a substrate of a film solar cell; (2) a packaging material possessing a reflection effect is adopted to substitute a titanium dioxide back reflection layer or a metal back reflection layer and a transparent packaging material; (3) a polymer composite film containing a metal layer is used as a back plate of the film solar cell; (4) an insulation tape is used to paste an electrode lead-out wire of a junction box; (5) a glue or an adhesive tape is used to seal film solar module edges; (6) a hook, which substitutes an aluminum frame, is bonded on the back of the film solar module so that the solar module can connect with an installing support. In the invention, the film solar module can be guaranteed to satisfy an IEC standard request; weight of an unit area of the film solar module can be reduced by 42%; simultaneously, production costs can be reduced and a production technology can be simplified.

Description

technical field [0001] The invention relates to a light-weight thin-film solar battery component and a manufacturing method thereof, and belongs to the field of solar battery device preparation. Background technique [0002] In recent years, the contradiction between environmental pollution and energy crisis and economic development has become more and more prominent, forcing people to devote themselves to the development of new renewable and clean energy. Solar energy is an inexhaustible, renewable and clean energy source. Rational use of solar energy is a long-term development strategy for human beings to solve energy problems. There are many ways for human beings to use solar energy, including photochemical conversion, photothermal conversion and photoelectric conversion, among which solar photoelectric conversion is to convert solar energy into electrical energy, and solar cells are devices that convert solar energy into electrical energy. Various countries have introdu...
