Abstract

The utility model relates to a low-reflection snow-melting and anti-pollution solar energy crystalline silicon battery member. The member includes a piece of glass which is carried out a low-reflection anti-pollution and self-cleaning process, an upper EVA film, crystalline silicon, a lower EVA film, a back film, a heat insulating film, and a back board. A film electric tracing and a soaking film are added between the crystalline silicon and the lower EVA film. Because the utility model adds the film electric tracing between the crystalline silicon and the lower EVA film, the snow-melting effect can be achieved by electrically heating the film electric tracing. Compared with the prior art which directly electrifies the crystalline silicon, the member of the utility model effectively protects the crystalline silicon. Through adding the soaking film between the crystalline silicon and the lower EVA film, the heat generated by the film electric tracing after being electrified can be evenly distributed on the surface of the crystalline silicon, thus having the function of protecting the crystalline silicon.

Description

Low reflection snow melt anti-soil solar energy crystal silicon cell component members

Technical field

The utility model relates to a kind of solar cell, refers to a kind of low reflection snow melt anti-soil solar energy crystal silicon cell component members especially.

Background technology

After Copenhagen meeting in 2009, be that the use of leading green energy resource is developed and universal rapidly with solar power generation, yet solar power generation is subjected to the influence of weather very big; In the wide thing backlands district of China and the solar energy resources in zone, plateau such as Xinjiang, Tibet very abundant, solar light irradiation intensity and hours of daylight when fine are all very abundant, be fit to very much utilize sunlight resource acquisition clean energy resource, but these areas just, winter, snowfall was many, and solar cell can not generate electricity after being avenged covering fully.Therefore, the method for the solar cell normal power generation in assurance these areas in winter and the abundant area of other snowfalls just is to guarantee that solar cell is not covered by accumulated snow.

To be direct electricity consumption heat or use the mechanical type snow-removing device to reach the effect of melting snow removing the crystalline silicon of solar cell heart portion existing technology; Mechanical device can't be worked in the severe snow weather and crystalline silicon might be worn out by electric shock for a long time easily, reduces service efficiency but so.

The utility model content

Main purpose of the present utility model is: a kind of solar energy crystal silicon cell component members of avoiding electric current directly to impact crystalline silicon and having the snow melt function again is provided.

For achieving the above object, the utility model provides a kind of snow melt anti-soil solar energy crystal silicon cell component members, includes glass, last eva film, crystalline silicon, following eva film, notacoria, thermal isolation film and backboard; It adds the film electric tracing between crystalline silicon and following eva film;

Add equal hotting mask between described crystalline silicon and the film electric tracing;

Described glass surface is coated with the low reflection of nanometer dirt-resistant self-cleaning plated film;

Described thin-film electro companion thermal recovery far infrared heats mode, and it can be made by materials such as metal, alloy, carbon crystalline substances;

Described equal hotting mask is made by high temperature resistant plastic material.

The utility model adds the film electric tracing between crystalline silicon and following eva film, thereby the effect that reaches snow melt is heated in its energising, directly to the crystalline silicon energising, has protected crystalline silicon compared to prior art effectively; And between crystalline silicon and film electric tracing, add equal hotting mask, the heat that film electric tracing energising back is produced intersperses among surface of crystalline silicon equably, when solar cell surface area is avenged, by heating that the film electric tracing is switched on, make the battery surface snow melting and with producing powerful hydrophilic layer between the snow cover, make accumulated snow can't be trapped in battery surface, need not manually to remove the snow and make photoelectric conversion rate obtain maximum assurance; Secondly,, therefore can guarantee the cleaning of glass surface for a long time, guarantee the photoelectric efficiency conversion to greatest extent and greatly reduce maintenance cost because the battery glass surface was carried out antistatic and dirt-resistant self-cleaning is handled.

Description of drawings

Fig. 1 is a generalized section of the present utility model.

Embodiment

A kind of low reflection snow melt anti-soil solar energy crystal silicon cell component members of the present utility model, as shown in Figure 1, include the surface and carried out the glass 12(glass use of the present utility model solar cell special glass that low reflection dirt-resistant self-cleaning is handled), last eva film 131, crystalline silicon 14, equal hotting mask 15, film electric tracing 16, following eva film 132, notacoria 17, thermal isolation film 18 and backboard 19, above-mentioned layers of material use frame 20 encapsulation fixing after carrying out lamination; Described solar cell special glass 12 surface-coated have the low reflection of nanometer dirt-resistant self-cleaning plated film 11.

The utility model adds film electric tracing 16 between crystalline silicon 14 and following eva film 132, to described film electric tracing 16 energisings, make its heating and heat is conducted to solar cell special glass 12 surfaces accumulated snow is melted, directly crystalline silicon is switched on compared to prior art, avoid electric current directly to the impact of crystalline silicon 14, make its load that is subjected to reduce to bottom line, protected crystalline silicon effectively, the design service life of assembly integral body when guaranteeing to dispatch from the factory; Described film electric tracing 16 adopts far infrareds to heat mode, and heating is fast, heat efficiency height, and it can be by metal, alloy, carbon is brilliant and other can be made the electrically heat tracing material of film and make; For the heat that film electric tracing 16 energising backs are produced intersperses among crystalline silicon 14 surfaces equably, so between described crystalline silicon 14 and film electric tracing 16, add equal hotting mask 15, this equal hotting mask 15 fits in film electric tracing 16 surfaces, and this equal hotting mask 15 is made by IXPE or other the high temperature resistant plastic materials that can make equal hotting mask; Be coated with the low reflection of nanometer dirt-resistant self-cleaning plated film 11 on described solar cell special glass 12 surfaces, when solar cell special glass 12 surface heats and after producing hydrophilic layer, accumulated snow, dirt just can't be stuck in solar cell surface of the present utility model, and can wash away along the solar cell surface landing of tiltably-mounted or by rainwater, the ability of its efficient snow melt anti-soil can guarantee the cleaning on solar cell special glass surface for a long time, guarantees the photoelectric efficiency conversion to greatest extent and greatly reduces maintenance cost.
