Abstract
The invention belongs to the technical field of preparation of solar components, and in particular relates to a post-coated color solar cell component and a preparation process thereof. During preparation of solar cells, a process of coating an antireflection coating is saved, the solar cells are welded, and a filter coating is coated in a unified way. Because the process of coating the antireflection coating is saved, the solar cells are welded, and the filter coating is coated in the unified way during the preparation of the solar cells, the solar cells are not shielded by the insulating antireflection coating, silver paste on the front surface can be easily contacted with a silicon slice well, the requirement of a screen printing process on paste is reduced, the cost is reduced, the packaged component has the same color and more attractive appearance, the photovoltaic and building integration requirement is met, and the component and the process are suitable for industrial production.
Description
Technical field
The invention belongs to solar module and make the field, relate in particular to the colored solar battery component and the preparation technology thereof of a kind of back plated film.
Background technology
At present the solar battery sheet color is single, and along with the continuous progress of photovoltaic industry, have higher requirement to the photovoltaic product in market, not only wants the continuous lifting of guaranteed efficiency, and the outward appearance of battery sheet has also been proposed harsher requirement.Especially photovoltaic and architecture-integral are more urgent to the demand of colored battery sheet, and for the photovoltaic product as construction material, people wish to select dress up oneself building of the color oneself liked, show the individual character of building.
It is to add to cover one deck filter coating on finished product battery sheet that single color solar cell flake products is arranged at present, make battery sheet display color, but its main grid line part is owing to will carry out the series welding connection, so can not cover filter coating, add to cover and the main grid line partly must be carried out mask before the filter coating, this way has caused increasing the operation of mask, increased production cost, and the total filter effect in original antireflective coating and filter coating stack generation is difficult to control, and can reduce the conversion efficiency of solar cell.
Summary of the invention
Purpose of the present invention is exactly colored solar battery component and the preparation technology thereof that a kind of back plated film is provided at the defective of above-mentioned existence, the present invention is in solar battery sheet manufacturing process, reduce the operation of coated with antireflection film, again solar battery sheet is welded, unified adding, covered one deck filter coating, the stopping of antireflective coating that has not had insulation, front side silver paste is easier to form good the contact with silicon chip, reduce the requirement of silkscreen process to slurry, reduce cost of manufacture, and made the assembly after the encapsulation realize same color, more attractive in appearance, satisfy photovoltaic and architecture-integral needs, be applicable to suitability for industrialized production.
The present invention is a kind of very single color solar module manufacture craft, technical scheme is: the colored solar battery component of a kind of back plated film, comprise the solar battery sheet that welds together by welding and backboard, EVA glued membrane, toughened glass layer etc., it is characterized in that, described solar battery sheet is coated with antireflection film not before printing and welding, the positive one deck filter coating that covers of the solar battery sheet after welding together by welding.
The described filter coating of described filter coating is one or more compositions in the dielectric materials such as oxide, fluoride, sulfide, nitride, tellurides, selenides.
The preparation technology of the colored solar battery component of a kind of back plated film, step is:
1. with after the step process such as the making herbs into wool of silicon chip process, cleaning, diffusion, edge insulation and dephosphorization silex glass, directly carry out silk screen printing, sintering, obtain solar battery sheet.
2. with after solar cell built-in testing, the go-on-go, with welding welding, the welding back is at the positive plating of battery sheet filter coating, stacks battery sheet behind backboard, EVA glued membrane, the plated film, EVA glued membrane, toughened glass layer at last successively, enter laminating machine and carry out lamination, form solar module.。
Beneficial effect of the present invention is: the present invention is in solar battery sheet manufacturing process; reduce the operation of coated with antireflection film; again solar battery sheet is welded; unified adding, covered one deck filter coating; reduced the operation of coated with antireflection film in the conventional solar battery sheet manufacturing process; simplified manufacture craft; add the filter coating that covers to the effect of electrode certain protection; and the stopping of antireflective coating that has not had insulation; front side silver paste is easier to form good the contact with silicon chip; reduce the requirement of silkscreen process, reduced cost slurry.
Can not exist total filter effect that the stack of original antireflective coating and filter coating produces on the solar battery sheet to be difficult to control, and the problem of the conversion efficiency of reduction solar cell, single filter coating makes filter effect adjusting more easy to control, and can Min. ground reduces the conversion efficiency loss of solar cell.
Solar module ratio after the encapsulation is easier to realize same color, and is more attractive in appearance, is suitable for the development principle of photovoltaic and architecture-integral, photovoltaic and environmental integration, is applicable to suitability for industrialized production.
Description of drawings:
Figure 1 shows that the traditional components structural representation;
Figure 2 shows that the colored solar battery module structure schematic diagram of back of the present invention plated film.
Among the figure, 1. backboard, 2.EVA glued membrane, 3. solar battery sheet, 4. antireflective coating, 5. welding, 6. toughened glass layer, 7. filter coating.
Embodiment:
In order to understand the present invention better, describe the technical solution of the utility model in detail with instantiation below, but the present invention is not limited thereto.
Technical scheme of the present invention is: the technological process of solar battery sheet 3 is making herbs into wool, cleaning, diffusion, edge insulation and dephosphorization silex glass, silk screen printing, test, and the solar battery sheet 3 that power is close with electric current is divided into same shelves.Compare with conventional solar cell, do not have the step of coated with antireflection film 4.
The solar battery sheet 3 that go-on-go is good carries out the monolithic welding, promptly welding 5 is welded on the front of solar battery sheet 3, wearing series welding afterwards connects, promptly solar battery sheet 3 is connected bunchiness with welding 5, the solar battery sheet 3 that will connect bunchiness is afterwards formed a matrix, with interconnecting strip welding 5 each polyphone is connect then; After this, carry out filter coating 7 preparations with arranging solar battery sheet 3 good and that connect.The solar cell piece 3 positive one deck filter coatings 7 that cover good and that connect will be arranged.
