Abstract
The utility model discloses a photovoltaic cell packaging plate adopting silica for sealing packaging and protecting. The photovoltaic cell packaging plate comprises a glass panel, first layer silica, a battery sheet string and second layer silica in sequence, therefore, the first layer silica replaces traditional vinyl acetate (EVA) materials on the front surface of a battery sheet, the shortcoming that the EVA absorbs short wave of sunlight is overcome, sunlight is utilized fully, power generation capacity of batteries is improved, and simultaneously weather resistance of the silica is far superior to the EVA, so that the power generation performance attenuation of the whole assembly is improved; the second layer silica replaces the EVA on the back surface of the battery sheet sting and a back plate, and material cost is remarkably saved; and further by means of the mode, damage to the battery sheet string during production is avoided, energy consumption is greatly reduced, production efficiency is improved, and comprehensive cost of the assembly is remarkably reduced.
Description
Technical field
The utility model invention relates to a kind of photovoltaic cell package board.
Background technology
At present, known solar-energy photo-voltaic cell encapsulation (lamination) plate structure is stacked by glass, two-layer EVA glued membrane, battery sheet string, backsheet layer and vacuumizes heating and pressurizing through laminating machine and form laminated sheet.There are many deficiencies in this encapsulating structure: 1.EVA material itself partly has bigger absorption to the shortwave of sunlight, makes sunlight not make full use of and has restricted the generating efficiency of assembly; 2.EVA the weatherability of material itself is not the most desirable, causes whole assembly generating capacity decay very fast; 3.EVA the glued membrane pressure sintering is produced, and silicon chip has certain breakage rate when causing producing; 4. this assembly production method time consumption and energy consumption; 5. back veneer material is with high costs.
The utility model content
The purpose of the utility model is to overcome the deficiency of present technology; A kind of photovoltaic cell package board that adopts silica gel sealing encapsulation and protection is provided, and the generating capacity that it can promote battery improves whole assembly power generation performance decay; Battery sheet string is damaged in the time of can avoiding producing; And greatly reduce energy consumption, promote production efficiency, thereby made the integrated cost of assembly be able to descend significantly.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
A kind of photovoltaic cell package board that adopts silica gel sealing encapsulation and protection comprises a face glass, ground floor silica gel, battery sheet string, second layer silica gel successively.
Said face glass is a ultra-white photovoltaic glass.
Said ground floor silica gel is high light-transmissive fluid silica gel.
Said second layer silica gel is high rigidity protection silica gel.
Said battery sheet string is the crystal silicon battery sheet.
Said battery sheet string is an amorphous battery sheet string.
The beneficial effect of the utility model is: adopt ground floor silica gel to replace the positive traditional EVA material of battery sheet; Improved the defective of EVA absorption sunlight shortwave; Make sunlight be able to more fully utilize; Promoted the generating capacity of battery,, whole assembly power generation performance decay has been improved simultaneously because the weatherability of silica gel is superior to EVA far away; Adopt second layer silica gel to substitute the EVA and the backboard at the battery sheet string back side, practiced thrift Master Cost significantly; And this mode not only can avoid producing the time battery sheet string damaged, and greatly reduce energy consumption, promoted production efficiency, thereby made the integrated cost of assembly be able to descend significantly.
Description of drawings
Fig. 1 adopts the photovoltaic cell package board structural representation of silica gel sealing and protection encapsulation for the utility model.
Embodiment
Below will specify the photovoltaic module of the employing silica gel sealing encapsulation of the utility model with reference to accompanying drawing.
As shown in Figure 1, the utility model adopts the photovoltaic cell package board of silica gel sealing encapsulation and protection to comprise a face glass 1, ground floor silica gel 2, battery sheet string 3, second layer silica gel 4 successively.
In the present embodiment, said face glass 1 is a ultra-white photovoltaic glass; Ground floor silica gel 2 is high light-transmissive fluid silica gel, heating cure or normal temperature cure when the production package board and get; Said battery sheet string 3 is a crystal silicon battery sheet string 3, and battery sheet string 3 also can be processed for amorphous battery material etc.; Said second layer silica gel 4 is high rigidity protection silica gel.
In the present embodiment, said battery sheet string 3 can use the battery sheet to replace, and the battery sheet is the crystal silicon battery sheet.
The mode of production of the utility model assembly mainly is divided into following a few step: the first step: face glass 1 is lain in (figure does not show, notes the cover glass face) on the working face, perfusion ground floor silica gel 2 on face glass 1; Second step: on ground floor silica gel 2, load onto battery sheet string 3; The 3rd step: perfusion second layer silica gel 4 on battery sheet string 3.Wherein, two-layer silica gel can normal temperature cure also can heat quick curing.This production technology has been cancelled the operation that vacuumizes hot melt and lamination in the traditional components production, and the defective of battery sheet string 3 breakages has reduced the breakage rate of assembly, thereby reduced the product material cost when having avoided the traditional components lamination to produce; In addition because the silica gel that uses only need 120 ℃ 2-3 minute promptly curable, greatly reduced energy consumption in 20-30 minute than 140 ℃-150 ℃ of traditional E VA technologies, promoted production efficiency.Thereby make the integrated cost of assembly be able to descend significantly.
In sum; In the present embodiment, adopt ground floor silica gel 2 to replace battery sheet string 3 positive traditional EVA materials, improved the defective of EVA absorption sunlight shortwave; Make sunlight be able to more fully utilize; Promoted the generating capacity of battery,, whole assembly power generation performance decay has been improved simultaneously because the weatherability of silica gel is superior to EVA far away; Adopt second layer silica gel 4 to substitute the EVA and the backboard at battery sheet string 3 back sides, practiced thrift Master Cost significantly; And battery sheet string 3 breakages not only can avoid producing the time of this mode, and greatly reduce energy consumption, promote production efficiency, thereby made the integrated cost of assembly be able to descend significantly.
