One, technical field
The invention belongs to the new forms of energy field of photovoltaic power generation, particularly a kind of flexible solar battery pack and preparation method thereof.
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, summary of the invention
Technical problem:
The present invention is directed to above-mentioned technological deficiency, a kind of flexible solar battery pack 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 battery pack, by top layer, last ethylene-vinyl acetate copolymer layer, toughened 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.
The method for preparing above-mentioned flexible solar battery pack, step is:
A. under 25 ℃ of room temperatures, the low iron toughened glass of high strength is lain against on the workbench, and spread high temperature cloth;
B. layer of transparent polyvinyl fluoride composite membrane and one deck upper strata ethylene-vinyl acetate copolymer successively tile on high temperature cloth;
C. put the low iron toughened glass of high strength of appropriate size on the ethylene-vinyl acetate copolymer of above-mentioned upper strata, one deck middle level ethylene-vinyl acetate copolymer again tiles on toughened glass;
D. the good solar battery sheet of will going here and there is tiled on the ethylene-vinyl acetate copolymer of middle level;
E. on above-mentioned solar battery sheet, cover one deck upper strata ethylene-vinyl acetate copolymer again;
F. the transparent polyvinyl fluoride composite membrane of tiling on the ethylene-vinyl acetate copolymer of upper strata is put laminating machine laminating into and is solidified;
The assembly cooling of g. lamination being come out is taken the high strength on top layer away and is hanged down iron toughened glass and high temperature cloth, obtains described flexible solar battery pack.
Wherein, the low iron toughened glass of described high strength is high printing opacity matte toughened glass or high printing opacity plain bar glass.
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 battery pack 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 battery pack 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.
