Problems solved by technology

However, the properties of PVB materials are quite different from those of EVA materials, and the solar cell sheets are easily broken. Using the manufacturing method of conventional laminated composite glass or the manufacturing method of EVA interlayer solar cell modules cannot produce usable solar cell modules.

Embodiment Construction

[0022] The present invention is described in detail with examples below.

[0023] 1. Glass cleaning: 888mm×864mm×6mm ordinary tempered glass is used for the back panel, and 888mm×864mm×6mm ultra-clear tempered glass is used for the panel, and both sides of the glass are cleaned with alcohol.

[0024] 2. Sorting of crystalline silicon solar cells: power screening of 156mm*156mm red polycrystalline silicon cells to ensure the consistency of the current, no damage to the appearance, and uniform color.

[0025] 3. Cutting of PVB film: Make the size of PVB sealant film slightly larger than solar photovoltaic glass by 5-8mm.

[0026] 4. Welding of crystalline silicon battery packs, welding monolithic crystalline silicon battery packs into crystalline silicon battery packs, including single welding, series welding, and sink welding. Keep the soldering temperature within the range of 350-370°C to avoid bad phenomena such as virtual soldering or tin tipping.

[0027] 5. Lamination of...

Abstract

The invention provides a making method of a color solar photovoltaic assembly, which satisfies the specification requirements of building safety glass and can be used for making enclosures at the outer side of a building, including a curtain wall, a roof, a sunshade, a door window, a barrier and a floor i.e. used for making a building integrated photovoltaic color solar photovoltaic assembly. In the making method, operation steps such as laminating pavement, assembly fixing, laminating curing, annealing treatment and the like are utilized. A product produced by the method has stronger peel strength without a frame for reinforcement, satisfies the shock resistance and the safety performance of the building safety glass and has elegant appearance.

Description

technical field [0001] The invention belongs to the fields of solar photovoltaic and building materials. In particular, it relates to a method for manufacturing a building-integrated (BIPV) solar photovoltaic power generation system or a colored solar photovoltaic module on a building roof or curtain wall. Background technique [0002] With the continuous reduction of fossil energy reserves such as coal, oil, and natural gas on the earth, the utilization of solar energy is being paid more and more attention by people. Solar photovoltaic module is a basic unit of solar power generation system, which converts solar energy into electrical energy by using the principle of solar photoelectric conversion. At present, the battery chips of solar photovoltaic modules are mainly monocrystalline silicon batteries, polycrystalline silicon batteries, amorphous silicon thin film batteries, CIS and CdTe compound thin film batteries, and the color of the photovoltaic modules made of these ...
