Embodiment 1

[0025] Embodiment 1, with reference to figure 1 , a crystalline silicon photovoltaic module, which includes a top cover plate 1, a first organic film 2, a crystalline silicon cell 3, a second organic film 4, and a back plate 5 that are stacked sequentially from top to bottom. A waterproof junction box is connected to the back plate 5, and the periphery of the assembly is provided with an aluminum alloy frame 6; the materials of the first organic film 2 and the second organic film 4 are silicone resin, epoxy resin, polyethylene One or both of alcohol butyral, ethylene-methyl acrylate copolymer, and polymethyl methacrylate; the light transmittance of the upper cover 1 is not less than 90%, and the strength of the upper cover 1 To withstand wind pressure of at least 2400Pa and snow pressure of 5400Pa; the back plate 5 is selected from composite films of multilayer polymers, tempered glass, modified PET films, and transparent TPT films. The crystalline silicon solar cells adopt s...

Embodiment 2

[0026] Embodiment 2, a method for preparing a crystalline silicon photovoltaic module as described in Embodiment 1, its specific steps are as follows:

[0027] (1) Preparatory process: Sorting the cells and pre-treating the ribbons; using a cutting machine to cut the organic film and the backplane to precise dimensions; the pretreatment method for the ribbons is: put the ribbons In the welding strip soaking tool, soak in the flux for 8 minutes, take it out and dry it;

[0028] (2) Welding: Welding is divided into single-piece welding and series welding. When welding, put the battery on the surface of a heating device, first preheat the battery at 55°C, and then use a 345°C electric soldering iron for welding. When the battery sheet and the electric soldering iron head are at an angle of 45°, the welding is performed by vertical welding or horizontal pull welding, and the welding speed is 2.5s / piece; for series welding, use a 345°C electric soldering iron on the series connecti...

Embodiment 3

[0034] Embodiment 3, a kind of preparation method of crystalline silicon photovoltaic module as described in embodiment 1, its specific steps are as follows:

[0035](1) Preparatory process: Sorting the cells and pre-treating the ribbons; using a cutting machine to cut the organic film and the backplane to precise dimensions; the pretreatment method for the ribbons is: put the ribbons In the welding strip soaking tool, soak in the flux for 5 minutes, take it out and dry it;

[0036] (2) Welding: Welding is divided into single-piece welding and series welding. When welding, put the battery on the surface of a heating device, first preheat the battery at 50°C, and then use a 330°C electric soldering iron for welding. When the battery sheet and the electric soldering iron head are at an angle of 30°, the welding is performed by vertical welding or horizontal pull welding, and the welding speed is 2s / piece; when connecting in series, use a 330°C electric soldering iron on the seri...

Abstract

The invention provides a crystalline silicon photovoltaic module which comprises a module body formed by stacking an upper cover plate, a first organic rubber film, a crystalline silicon cell, a second organic rubber film and a rear panel sequentially from top to bottom. A waterproof connection box is connected on the rear panel, and an aluminum alloy frame is arranged on the periphery of the module body. The invention further discloses a preparation method of the crystalline silicon photovoltaic module. The preparation method includes the steps of preparation, welding, assembly, detection, lamination, lamination after-treatment, framing and subsequent treatment. The crystalline silicon photovoltaic module is efficient, stable in voltage output, firm, reliable, permanently stable and extremely applicable to terrestrial and roof power stations. By the preparation method, feeding and production assembly line processes are reasonably configured, process flow is optimized, manufacture time of the module is shortened, and high quality and batch stability of the module are guaranteed.

Description

technical field [0001] The invention provides a crystalline silicon photovoltaic component and a preparation method thereof, belonging to the technical field of solar photovoltaics. Background technique [0002] Solar energy is a clean, efficient and inexhaustible new energy source. It is one of the important renewable energy sources and an important part of the sustainable development strategy of governments in resource utilization. On the one hand, solar energy, as a new energy and renewable energy that produces little or no pollution to the environment, is an important alternative energy source that cannot be compared with high-carbon fossil energy in terms of pollutant emissions; on the other hand, it is widely used in my country. On the country's land, solar energy is an energy source that needs to be supplemented urgently. Using solar energy independent power generation systems to solve power supply problems for remote areas and coastal islands that lack or have no elec...
