A double-glass solar photovoltaic module

technical field

The utility model relates to a solar component, in particular to a double-glass solar photovoltaic component.

Background technique

With the development of world industry, oil, natural gas, coal and other resources are being exhausted day by day, and human beings' thinking about resources has led to great development of solar energy utilization technology. As the most important optoelectronic device for solar photovoltaic power generation, solar cell modules play an important role in the practice of photovoltaic power generation and building integrated photovoltaics. Nowadays, most modules use traditional structures for photovoltaic module packaging, which have low conversion efficiency, low light utilization rate, and no decorative effect.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a double-glass solar photovoltaic module.

In order to achieve the above object, the double-glass solar photovoltaic module is characterized in that the double-glass solar photovoltaic module includes a first glass layer, a first EVA material layer, and a single crystal solar cell layer sequentially compounded from top to bottom. , the second EVA material layer and the second glass layer.

Preferably, both the first and second glass layers are tempered glass.

Preferably, a plurality of single crystal solar cells arranged in a matrix are arranged on the single crystal solar cell layer, and the interconnection bars connecting each single crystal solar cell are tin-coated copper strips.

The beneficial effect of the utility model is that, the application of the double-glass solar photovoltaic module can receive the irradiation of sunlight on both sides, which increases the power generation power of the module; the double-sided tempered glass increases the impact resistance; The soft tin-coated copper strip is used as the interconnection strip to connect the solar cells in series, which reduces the internal resistance of the module and achieves higher conversion efficiency; at the same time, the EVA material is used as the packaging and sealing material, which can be used in the production equipment. The laminator does not need to be equipped with a PVB autoclave, which saves production costs.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:

Figure 1 shows a schematic structural view of the double-glass solar photovoltaic assembly described in the present invention. As shown in Figure 1, the double-glass solar photovoltaic assembly includes the first glass layer 1, the second glass layer, which are sequentially compounded from top to bottom. An EVA material layer 2, a single crystal solar cell layer 3, a second EVA material layer 4 and a second glass layer 5, each layer structure is made by a lamination process, and the double-glass solar photovoltaic module is beautiful and has good performance. Decorative effect, both low-carbon and environmentally friendly energy supply.

In order to increase the impact resistance of the double-glass solar photovoltaic module, the first glass layer 1 and the second glass layer 5 both adopt tempered glass with high light transmittance to replace the traditional back plate; at the same time, EVA material is used as the package seal For materials, ordinary laminators can be used on the production equipment without additional configuration of PVB autoclaves, which saves production costs.

In addition, Fig. 2 shows a schematic diagram of front welding of the single crystal solar cell panel layer shown in Fig. 1, as shown in Fig. The battery sheet 31, the interconnection strip 32 connecting each of the single crystal solar battery sheets 31 is a low-resistivity ultra-soft tin-coated copper strip, which reduces the internal resistance of the double-glass solar photovoltaic module and can achieve higher conversion efficiency. At the same time, in order to ensure that each single crystal solar battery piece 31 is placed correctly, the sides of some single crystal solar battery pieces 31 are cut with rounded corners, thereby ensuring the quality of the solar battery panel preparation.

In summary, the above are only preferred embodiments of the present utility model, and are not intended to limit the implementation scope of the present utility model. That is, all equivalent changes and modifications made according to the patent scope of the utility model should belong to the technical category of the utility model.
