Abstract

A self-cleaning solar cell array comprises a frame, a base plate, a plurality of solar cells, and bonding material and a connecting strip, which is characterized in that: on the light-facing surface of the solar cells, i.e. on the top of the solar cell array is arranged a piece of nanometer self-cleaning glass. The solar cell array has a self-cleaning ability to remove contaminations such as organic or inorganic dust, dirt and water.

Description

A kind of automatically cleaning solar module

Technical field the utility model relates to a kind of automatically cleaning solar module, particularly a kind of crystal silicon solar battery component with the nano material encapsulation.

Background technology crystal silicon solar battery component (photovoltaic module) adopts high transmission rate, high strength glass material to encapsulate usually, and the assembly array (photovoltaic array) that its multicompartment constitutes is all at outdoor location.For a long time, the packaged glass cleaning surfaces problem of photovoltaic module or array is perplexing its normal use always, and is usually with artificial cleaning, not only time-consuming, take a lot of work, have potential safety hazard when needing, and can not in time implement.And the organic or inorganic dirt in the outdoor environment, dirt pollute and to cause not only light transmission rate to reduce to cause that generating efficiency reduces under the same light radiation condition, also can cause " hot spot " effect (as the birds droppings pollution etc.) to cause assembly or array to damage sometimes.

The content the purpose of this utility model of invention is to overcome above-mentioned deficiency, and a kind of automatically cleaning ability that has is provided, and can clean the solar module of the pollution of organic or inorganic dirt, dirt and water voluntarily.

The technical solution of the utility model is: this automatically cleaning solar module, comprise frame 1, base plate 2, some groups of solar battery sheets 3, bonding agent 4 and interconnectedly be with 6, its characteristics are on the top of the side to light of solar battery sheet (array) 3 a nano self-cleaning glass 5 to be housed.

Another characteristics of the present utility model are that described nano self-cleaning glass 5 is nano-coating glass.

Another characteristics of the present utility model are that described nano self-cleaning glass 5 is at the multiple film glass of surface of plate glass coated with nano.

The utlity model has following advantage and effect: 1, clean inorganic spot: photovoltaic module, array can regularly spray by the normal erosion or the artificial water of natural rainfall, can guarantee that glass cleaning is pure and fresh.

2, clean organic spot: by photocatalysis, the nano self-cleaning film can effectively decompose the organogenous sediment that is covering at photovoltaic module, array package glass surface.

3, the natural cleaning of photovoltaic module, array package glass surface can make it keep higher sunlight transmitance, thereby improves generating efficiency and energy output.

4, can exempt artificial cleaning, the man-hour of avoiding causing thus, expense, safety problem etc.

5, the photovoltaic module that can avoid organic or inorganic dirt, dirt in the outdoor environment to pollute naturally causing, array " hot spot " effect (as the birds droppings pollution etc.) make assembly or array exempt from damage.

Embodiment

As Fig. 1, Fig. 2, the utility model by around on every side bonding agent (EVA) 4 of base plate 2, some groups of solar battery sheets (array) 3, solar battery sheet (array), the electric connection line between the solar battery sheet of frame 1, bottom interconnected with 6, the nano self-cleaning glass 5 on solar battery sheet (array) side to light top forms.Nano self-cleaning glass 5 can be nano-coating glass, also can be the multiple film glass of surface of plate glass coated with nano.

7-is a sealing strip among the figure; 8-is a terminal box; 9-is a power outlet.

Nanometer film on the nano self-cleaning glass 5 and the reaction of the ultraviolet ray in the sunray can produce double action: first catalytic action, can drop on organic substance on glass so that the far ultraviolet in the visible light decomposes, and organic dirt is come to naught; Its two it that glass surface is become is hydrophilic, can raindrop or fog becomes a thin layer and make glass surface moistening, and wash the foul of glass surface off.Also can film and form the multiple film glass 5 of nanometer at the titanium dioxide optical catalyst that surface of plate glass has applied layer of transparent.After the titanium deoxide catalyst film that is called as " photocatalyst " runs into the solar ultraviolet irradiation, become carbonoxide and water and elimination automatically at organic substance, the pollutant that can make the transparent titanium dioxide surface attachment on the glass surface layer under the excited state of ambient light.

The utility model---automatically cleaning solar module has following characteristic:

1, use photovoltaic module, the array surface of self-cleaning nona glass to have super hydrophilicity. This characteristic can Come so that moisture is sprawled at glass surface fully equably, and fully infiltrate glass and pollutant, and Gravity by water will be attached to pollutant on glass and carry away, and can be as usually forming at glass plate The globule adheres to dust, thereby reaches the automatically cleaning effect of photovoltaic module, array, and keeps the length on its surface The phase cleaning.

2, photovoltaic module, array surface have the photo-catalysis function of decomposing organic matter. This photocatalytic activity reaction Refer to: under the irradiation of sunlight or ultraviolet light, the self-cleaning nona thin-film material of photovoltaic module, array surface pair Organic matter can have strong decomposition, and any effect can not take place to inorganic matter.

3, photovoltaic module, array surface have antifogging action. Because treated glass surface has super close The water-based energy, moisture can't form the globule at substrate surface, but forms uniform moisture film, thereby can make light Photovoltaic assembly, array surface have anti-fog function.
