The content of the invention

The utility model is in order to make up the deficiencies in the prior art, there is provided a kind of generating efficiency is high, and good heat dissipation effect is too Positive energy photovoltaic module, solves problems of the prior art.

To achieve these goals, the technical solution adopted in the utility model is：

A kind of solar photovoltaic assembly, including be arranged on the framework of surrounding, be provided with the inside of the framework the first rib and Second rib；It is described to be disposed with filter layer and ultra-clear glasses layer from the bottom to top above the first rib；First rib And second be from top to bottom provided with light transmission protective layer, silica coating, solar panel and backboard between rib；It is described super The first closed cavity is formed between white glass layer, the filter layer and the framework；The filter layer, printing opacity protection The second closed cavity is formed between layer and the framework；Indifferent gas is filled with first cavity and second cavity Body.

In a possible implementation, the backboard bottom surface, the lateral surface of the framework offer poly-V-grooved.

In a possible implementation, the thickness of the silica coating is 0.1-1mm.

In a possible implementation, the filter layer includes algaas semiconductor film, telluride successively from top to bottom Cadmium semiconductor film and gallium arsenide semiconductor film.

In a possible implementation, filled with bonding between the light transmission protective layer and the silica coating Layer, the tack coat is ethylene-vinyl acetate copolymer, and its thickness is 0.2-0.8mm.

In a possible implementation, the material of the solar battery sheet is monocrystalline silicon or polysilicon, it is described too The thickness of positive energy cell piece is 100 microns~300 microns.

In a possible implementation, the thickness of the ultra-clear glasses is 2mm-5mm.

Relative to prior art, solar photovoltaic assembly provided by the utility model, the advantage is that：

1st, the present apparatus is by setting by the algaas semiconductor film on upper strata, the cadmium telluride semiconductor film in intermediate layer and lower floor Filter layer made of gallium arsenide semiconductor film, the reflection and scattering of light can be effectively reduced when sunshine enters the present apparatus, And filtered the light of the unwanted wavelength of solar panel, only allow effective sunlight to pass through, turn so as to improve photoelectricity The efficiency changed.

2nd, by setting the first cavity and the second cavity in the both sides up and down of filter layer, and indifferent gas is filled wherein Body, effectively caused heat on filter layer can be transmitted, so as to reduce the internal temperature of photovoltaic module, prevent its mistake Heat and to influence cell panel overheat impaired.

3rd, in the utility model, framework is specifically also arranged to thin-wall construction, and in backboard bottom surface and the appearance of framework Face sets V-shaped groove, adds surface area, further increases radiating efficiency, so as to ensure effective radiating of photovoltaic module, improves Photoelectric transformation efficiency and extend service life.

4th, in the meridian hour in summer, even if after sunshine passes through filter layer, the intensity of illumination of light is still very strong, this On solar panel, if photoelectric transformation efficiency will not only improve kind of light direct irradiation, on the contrary can be due to light mistake Elevate the temperature by force and cause photoelectric transformation efficiency not rise anti-drop, therefore light transmission protective layer and titanium dioxide are set under filter layer Silicon film, it can be reflected and be scattered after light enters light transmission protective layer and silica coating, last light is still photograph To penetrate on solar panel, photoelectric transformation efficiency is unaffected, but effectively can completely cut off temperature in the second cavity, Prevent the rise of solar cell plate temperature.

In summary, solar photovoltaic assembly of the present utility model is rational in infrastructure, than the photovoltaic of prior art Heat-sinking capability is strengthened while the electricity conversion of component is improved, and reduces manufacturing cost, improves use In the life-span, it is especially suitable for promoting the use of.
