Description
Technical field
The utility model belongs to solar photoelectric applied technical field, particularly relates to the structure of cell piece tissue in a kind of solar module.So-called cell piece tissue refers to the indispensable basic element of character of preparing solar module, and it comprises some solar battery sheets and painting tin copper strips for being connected cell piece electrode.Cell piece tissue combines and can be made into solar module with series connection summarizing module.
Background technology
Energy supply at present worldwide enters into epoch in short supply, and a large amount of sustainable new forms of energy are by people's extensive use, and now main is to utilize solar water heater and solar energy to change into the solar panel of electric energy.Wherein solar power generation is more and more subject to people's attention, and people are laid on roof, ground etc. by solar panel and are combined into photovoltaic plant.
In conventional solar module, the structure of cell piece tissue as shown in Figure 1 or 2, there are two problems that have a strong impact on energy output in it: the one, because solar panel must be placed in open-air atmosphere, thereby always have the objects such as fallen leaves, flying bird, dust and block, these shelters have just formed shade on solar panel; The 2nd, solar panel, under the impact of a series of external force such as transport, a dead lift, installation, can cause that cell piece is damaged, hidden splitting.Above 2 all can be caused energy output to reduce, and affect the output of power.Because common solar panel is generally joined end to end with welding by some cell pieces, series connection or series connection and combination in parallel, after lamination, be encapsulated in a metal framework, the positive solar battery cell (cell piece) of making for silicon chip is cascaded, reverse side is that a terminal box is with positive-negative polarity connecting line, several diodes, once if there is a certain cell piece to be blocked or damage, will affect the generating output of whole solar panel.
The cell piece of crested in one series arm, will be taken as other energy that have the cell piece of illumination to produce of load consumption.The solar panel of crested now can generate heat, Here it is hot spot effect.The serious destruction cell piece of this hot spot energy.The portion of energy that has the cell piece of illumination to produce, all the cell piece of possibility crested consumes, and badly influences whole group and generates electricity useful life.In order to prevent that cell piece is because hot spot effect causes damage, a bypass diode in parallel between the both positive and negative polarity of solar panel conventionally.When assembly has bypass diode, after a cell piece is blocked by 100%, normal with its other cell piece on the same group, flow through the electric current that blocks cell piece and be greater than its photogenerated current, therefore the terminal voltage of this cell piece becomes negative, now it has become load absorbed power, after bearing to a certain extent, bypass diode conducting, this group that has shade cell piece is bypassed, avoid hot spot, be not damaged with protection assembly, although this way can have certain protection to solar panel, but bypass the group of shade cell piece, will waste the generated energy of this other cell piece of group, thereby can have influence on the generated output output of monoblock cell panel.Also have a kind of possibility, because cell piece group belongs to series connection, if a slice cell piece has part to be blocked or damage, the generating output of this cell piece place group will all can be affected.
Summary of the invention
The utility model, for prior art deficiency, has proposed a kind of structure of solar battery sheet tissue, and this cell piece tissue can be used for preparation and can not blocked or damaged and affect the battery component of its generated output output because of cell piece wherein.
The present invention solves the technical scheme that its technical problem takes, the structure of cell piece tissue in a kind of solar module, described cell piece tissue comprises some cell pieces and painting tin copper strips for being connected cell piece electrode, the described cell piece vertical ordered arrangement in column of laterally embarking on journey, it is characterized in that, cell piece is anodal and anodal, and by being coated with, tin copper strips is connected and cell piece negative pole is connected by being coated with tin copper strips with negative pole.
As preferably, described cell piece is anodal and anodal is that the positive pole of each row cell piece is connected in series bunchiness and each row cell piece and is connected in parallel into net by painting tin copper strips respectively with the positive pole of cell piece adjacent in adjacent columns cell piece by being coated with tin copper strips respectively by being coated with that tin copper strips is connected; Described cell piece negative pole and negative pole are that by being coated with, tin copper strips is connected in series bunchiness and each string is connected in parallel by being coated with tin copper strips respectively for the negative pole of each row cell piece by being coated with that tin copper strips is connected.
Innovation of the present utility model is the structure of cell piece tissue, and more particularly, the feature of the structure of the cell piece tissue of this novelty is that positive pole is connected with positive pole, and negative pole is connected with negative pole; Especially anodal and anodal be connected to have adopted between each cell piece not only connect but also the netted connected mode of parallel connection.
Adopt cell piece tissue of the present utility model to can be used for preparing a kind of follow-on solar module, it can not blocked or damaged and affect generated output output because of cell piece wherein.That is to say, when the cell piece in this solar module is in the time being blocked or damage, be only limited to the cell piece that is blocked or the damage generating of not working, and whole assembly generator unit is unaffected, can ensure normal power generation.
Combined with series connection summarizing module by cell piece tissue of the present utility model, can be made into above-mentioned follow-on solar module, but the concrete preparation method of this solar module does not belong to task of the present utility model, does not repeat them here.
