Problems solved by technology

Since the tempered glass cannot be cut or bent, the existing lamination packaging method only supports flat tempered glass
Due to the limitation of the production process, BIPV modules have a single form, and most of them are flat and regular, so that photovoltaic applications cannot better cut into the architectural design concept

Embodiment 1

[0027] Such as figure 1 As shown, a curved surface BIPV photovoltaic module according to the present invention includes a glass front cover plate 1, an adhesive layer 2, a solar cell 3, another adhesive layer 4 and a glass back plate 5 laminated in sequence. The solar cell 3 is formed by crystalline silicon solar cells or flexible thin film cells 31 arranged in series and welded in series at certain intervals, and consists of a glass front cover layer 1, an adhesive layer 2, a solar cell 3, and an adhesive layer. 4 and the glass back plate layer 5 are laminated to form a bending area B on the photovoltaic module, and the bending area B is placed between two rows of the solar cell array. In the present invention, the glass front cover plate 1 and the glass back plate 5 are all made of ultra-clear float glass with high transmittance, and the adhesive layers 2 and 4 are PVB film layers, or other polymers It is made of adhesive film layer, and the distance between the solar cells...

Embodiment 2

[0038] This embodiment is basically the same as the first embodiment above, except that the heating method of the infrared lamp in the above step (5) is replaced by the heating method of carbon dioxide laser.

Abstract

The invention belongs to the application field of photovoltaic manufacturing, and especially discloses a curved-surface-BIPV-photovoltaic-assembly and a preparation technology thereof. The curved-surface-BIPV-photovoltaic-assembly comprises a glass front cover plate, a first binder layer, a solar battery, a second binder layer and a glass backboard which are laminated sequentially. The solar battery is formed by crystalline silica solar battery pieces or flexible film battery pieces which are in array arrangement at certain intervals and which are welded and in series with each other. The photovoltaic-assembly formed by laminating the glass front cover plate, the first binder layer, the solar battery, the second binder layer and the glass backboard is provided with a curved area. The curved area is arranged to be in the position between two lines of the solar battery array. The curved-surface-BIPV can be bent at positions according to needs, so that the form of the BIPV assembly can be diversified, and the photovoltaic assembly is enabled to perfectly merge into modern building designing. The diversification of photovoltaic products is better realized. In addition, the manufacturing methods are simple and convenient.

Description

technical field [0001] The invention belongs to the application field of photovoltaic manufacturing, and specifically discloses a curved surface BIPV photovoltaic module and a preparation process thereof. Background technique [0002] In the existing technology, distributed small-scale photovoltaic power generation systems are more and more widely used, and the demand for building integrated photovoltaics (BIPV for short) is stronger. [0003] At present, the combination of photovoltaic modules and buildings mainly includes roofs, windows, curtain walls, etc., and the structure is mostly double glass modules or hollow glass modules. Building standards clearly state that buildings must use safety glass such as tempered glass, and most existing BIPV components use ultra-clear tempered glass. The commonly used production method of BIPV modules is to laminate polymer adhesive layers such as EVA / PVB in the middle, and then use a laminator for lamination, and some are further pro...
