Description
One, technical field
The invention belongs to the new forms of energy field of photovoltaic power generation, particularly a kind of flexible solar module.
Two, background technology
Prior art: because global energy crisis and environmental problem is increasingly serious; people are more and more urgent to the demand of new forms of energy and pollution-free regenerative resource, and solar energy power generating is rising in a new and renewable sources of energy technical field.
The primary element of solar energy power generating is the solar battery cell sheet, and monocrystalline silicon, polysilicon, amorphous silicon and hull cell etc. are arranged.The solar panel of being made up of one or more solar battery sheets is called photovoltaic module, or solar module, solar module be a kind of be the device of electric energy with conversion of solar energy, have that installation form is various, safety non-pollution, inexhaustible advantage, so obtained development energetically.
Current, the application of solar cell has entered departments such as industry, commerce, agricultural, communication, household electrical appliance and public utility from military field, space industry, especially can be dispersedly in the outlying district, high mountain, desert, island and rural area use, to save the very expensive transmission line of cost.But at this stage, its cost is also very high, and sending the 1kW electricity needs up to ten thousand dollars of investment, and therefore extensive use still is subjected to restriction economically.But; in the long run; invention along with the improvement of solar cell manufacturing technology and new light-electrical switching device; various countries are to the protection of environment with to the great demand of regeneration clean energy resource; solar cell will be to utilize the more practicable method of solar radiant energy, can be to utilize solar energy to open vast vistas on a large scale human future.
But common solar module mostly is board-type greatly at present, the exhibition of inflexibility folding, and the performance of hail suppression simultaneously is not good yet.
Three, utility model content
Technical problem:
The present invention is directed to above-mentioned technological deficiency, a kind of flexible solar module is provided, to solve the inflexible problem of conventional solar cells assembly.
Technical scheme: technical solution of the present invention is:
A kind of flexible solar module, by top layer, last ethylene-vinyl acetate copolymer layer, high-strength armoured-glass layer, middle ethylene-vinyl acetate copolymer layer, solar cell layer, following ethylene-vinyl acetate copolymer layer and backsheet layer, stack gradually from top to bottom and arrange, encapsulation constitutes, and described top layer and backsheet layer are transparent polyvinyl fluoride composite membrane.
Wherein, the low iron toughened glass of described high strength is high printing opacity matte toughened glass or high printing opacity plain bar glass.Described solar cell layer is monocrystalline silicon, polysilicon or non-crystal silicon solar cell.
Beneficial effect:
The present invention is directed to existing solar module can not crookedly roll over the shortcoming of opening up, and a kind of flexible flexible solar battery pack is provided.This solar module adopts transparent TPT material (polyvinyl fluoride composite membrane) as panel material, uses high EVA (ethylene-vinyl acetate copolymer) glued membrane of the anti-aging degree of multilayer, and backboard also adopts transparent TPT material (polyvinyl fluoride composite membrane) simultaneously.
Flexible solar module of the present invention has the following advantages:
1, can crooked according to actual needs certain radian;
2, owing to adopted the anti-aging EVA material of high-performance, long service life; Owing to adopted the good transparent TPT material of weatherability, had good daylighting effect.
3, component internal adopts high printing opacity plain bar glass or the encapsulation of high printing opacity matte toughened glass, and very high light transmittance is arranged, and can improve the photovoltaic module conversion efficiency.
4, flexible solar battery pack of the present invention has good hail suppression, can use under various complicated harsh climate conditions
Flexible solar module of the present invention is applicable to that solar energy electric roof, car skylight etc. need the place with the crooked certain radian of assembly.
Four, description of drawings
Fig. 1 is the three-dimensional exploded view of flexible solar module of the present invention.
Among the figure, the 1-top layer; The last ethylene-vinyl acetate copolymer layer of 2-; 3-high strength is hanged down iron toughened glass layer; Ethylene-vinyl acetate copolymer layer among the 4-; The 5-solar cell layer; Ethylene-vinyl acetate copolymer layer under the 6-; The 7-backsheet layer.
