Abstract

A solar cell module comprises a base (1) and a solar wafer (2), wherein the solar wafer (2) is placed in a groove (3) in the top of the base (1) and is packaged by a silica gel layer (4), a glass plate (5) is packaged above the solar wafer (2) and on the top surface of the silica gel layer (4), and the solar cell module has the advantages of excellent light transmittance and aging resistance, long service life, simple manufacturing process and low production cost.

Description

A kind of solar module

1, technical field:

The utility model relates to a kind of solar module.

2, background technology:

Producing the method for solar module at present, is to adopt the coated encapsulation of epoxy resin or carry out the lamination encapsulation with the EVA resin.The epoxylite encapsulation has a strong impact on the useful life of solar module because of the restriction of epoxy resin self performance.Out of doors under the weather conditions, the ageing-resistant performance of epoxy resin is not good, will turn to be yellow and chap after 2 years, and light transmittance is up to 86% when just solidifying, after 2 years just less than 83%, so with the long life of the solar module of epoxy encapsulation be 2 years, thereby be unsuitable for the solar module that the long-life requires.Need laminating machine to produce when encapsulating, and the cycle is long with EVA, the cost height, little in batches, can not produce assembly less than 2W.When its solar module was exposed to the sun out of doors, maximum temperature can reach 85 ℃, and EVA is unstable properties under this temperature, easily decomposed and variable color, so also be not suitable for battery component three encapsulating structures.

3, summary of the invention:

The purpose of this utility model provides a kind of solar module; it adopts glass plate and silica gel to carry out coated encapsulation; because the light transmittance of glass and silica gel and ageing-resistant performance are very excellent; silica gel has elasticity again, can absorb extraneous stress, can play the purpose of protection solar wafer; so can be improved greatly the useful life of solar module; whole light transmission also greatly improves, and technology is simple, and production cost is also cheaper.

The utility model is achieved by the following technical solution: it comprises base, solar wafer, and solar wafer is positioned in the groove of base top and with the layer of silica gel encapsulation, above solar wafer, the end face of layer of silica gel is packaged with glass plate.

The utility model compared with prior art has following advantage: adopt glass and silica gel to carry out coated encapsulation, the light transmittance of glass and ageing-resistant performance be excellence very, and its light transmittance reaches 94%, and out of doors under the weather conditions, character is constant in 50 years.The light transmittance of silica gel reaches as high as 94%, basic nondiscolouring in the resistance to ag(e)ing 8 years.In addition, silica gel has resistance to oxidation, high-low temperature resistant alternation, cold-resistant and anti-ozone, also has good performances such as excellent electrical insulating property and humidity.Silica gel has elasticity; can absorb extraneous stress; can play the purpose of protection solar wafer; so so can be greatly enhanced the useful life of the solar module of encapsulation; minimum more than 8 years, whole light transmission also greatly improves, and light transmittance reaches more than 90%; manufacturing process is simple, and production cost is also cheaper.

4, description of drawings:

Below in conjunction with accompanying drawing the utility model is done detailed explanation:

Fig. 1 is a solar module encapsulation schematic diagram of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the schematic diagram before the utility model cover glass;

5, embodiment:

As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises base 1, solar wafer 2, and solar wafer 2 is positioned over 3 li of the grooves at base 1 top and with layer of silica gel 4 encapsulation, above solar wafer 2, the end face of layer of silica gel 4 is packaged with glass plate 5.

During manufacturing, place solar wafer 2 in base 1, then silicone fluid is poured in the groove 3 of the base 1 that keeps flat, cover glass plate 5 then and leave standstill a period of time, silicone fluid solidifies solar wafer 2, forms layer of silica gel 4.

Claims

1, a kind of solar module, comprise base (1), solar wafer (2), it is characterized in that solar wafer (2) is positioned over groove (3) lining at base (1) top and with layer of silica gel (4) encapsulation, is packaged with glass plate (5) at the top of solar wafer (2), the end face of layer of silica gel (4).
