Abstract
A packaging structure of solar cell module comprises a battery unit formed by connections of a plurality of battery slices. A plurality of battery slices in the battery unit are arranged in a regular array and the battery slices in the same row are connected with each other in serial and the battery slices of each row are connected with each other in parallel. The connection in serial is realized using the flowing method: one end of the traditional thin welding belt is in welded connection with the front-face electrode of the back battery slice and another end thereof is in contact connection with the back electrode of the next battery slice and the welding belt is cemented with the back electrode by a conducting resin. The solar cell module uses the conducting resin to connect the battery slices in replace of the traditional welding belt with no or little welding technique, therefore the fragment ratio due to bow action and the possibility of subfissure and back electrode damage are greatly reduced. At the same time the module transfer efficiency is increased. The raw material is saved and the module package cost is reduced.
Description
Technical field
The utility model relates to solar cell, particularly a kind of encapsulating structure of solar module.
Background technology
Independent crystal silicon solar battery sheet energy output is little, and very frangible, inconvenient actual the use.A plurality of battery sheets to be packaged into assembly in the practical application.At present solar module is mainly with the packaged type of battery sheet series connection, and the battery sheet be in the assembly the most key while also be the highest raw material of cost accounting.Traditional battery sheet connected mode is a soldering copper conduction band between positive and negative electrode, and welding itself can be to battery sheet localized heating, and this can cause the bow action of battery sheet, thereby in lamination and lamination process, causing fragment and sliver rate to increase, this can greatly influence the reliability and the manufacturing cost of product quality.Though numerous assembly producer by the whole bag of tricks, optimizes technological process, the research welding temperature is used various templates, in the hope of reducing the battery sheet amount of crimp that produces because of being heated in the encapsulation process.But the fact shows that the bow action of battery sheet still can not be avoided.As long as the battery sheet is heated, because the thermal coefficient of expansion of aluminium paste coating and silicon layer is different, will cause the battery bending tablet, that is to say as long as still adopt the method for welding, just can not avoid the bow action of battery sheet.And welding to the influence of assembly far not only that, localized heating is near the inhomogeneity destruction of the back electrode battery sheet grid line, also can cause the local internal stress skewness and cause latent splitting, significantly reduce working life, if rosin joint sealing-off then more can directly influence the overall performance electrical performance of battery component, and because the restriction of main grid line width, connect used welding rod width less than 2mm, this will finish good welding operation for artificial very difficult, and will finish welding accurately for machine just needs very complicated debugging and maintenance process.
The utility model content
The purpose of this utility model is to overcome the problem that above-mentioned prior art exists, and a kind of encapsulating structure of new solar module is provided.
The purpose of this utility model is achieved in that a kind of encapsulating structure of solar module, comprise the battery pack that connects into by a plurality of battery sheets, a plurality of battery sheets in the battery pack are arranged in neat array, be connected in series between each battery sheet of same row, each is arranged the battery sheet and is connected in parallel, be characterized in, being connected in series between described each battery sheet is to be welded to connect with an end of the thin welding of tradition and the front electrode of a last battery sheet, the other end contacts with the back electrode of next battery sheet and links to each other, and with conductive tape welding and back electrode is bonded together.
The width of described conductive tape is greater than back electrode grid line width, and length is not less than 80% of battery leaf length.
The thickness of described conductive tape is 0.1-0.2mm.
The encapsulating structure of solar module of the present utility model is owing to adopt conductive tape to replace traditional welding, be used for the connection between the battery sheet, need not weld, or few with welding, can reduce the fragment rate that bow action causes greatly, reduce latent splitting and the possibility of destroying back electrode greatly.Simultaneously also can improve the assembly conversion efficiency, save material, reduce the component package cost.

Embodiment
Referring to Fig. 1, the encapsulating structure of the utility model solar module, the battery pack 4 and the glass cover-plate 5 that comprise frame 1, base plate 2, adhesive linkage 3, connect into by a plurality of battery sheets.Frame 1 and base plate 2 connect into a bucket type structure, and adhesive linkage 3 is arranged on the base plate, and battery pack 4 is arranged on the adhesive linkage 3, and glass cover-plate 5 covers on the battery pack 4.Shown in Fig. 1,6 is lead wire sheath, and 7 is contact conductor, and 8 is the frame packaging plastic, and 9 is series conductor.
Referring to Fig. 2, Fig. 3, Fig. 4, being connected in series between each battery sheet 41 of same row is to be welded to connect with an end of the thin welding 42 of tradition and the front electrode of a last battery sheet in the utility model, the other end contacts with the back electrode of next battery sheet and links to each other, and with conductive tape 43 welding and back electrode is bonded together.The width of conductive tape is greater than back electrode grid line width, and length is not less than 80% of battery leaf length, and thickness is 0.1-0.2mm.
In practical operation, conductive tape is cut by the 30mm width, guarantee that width greater than back electrode grid line width, cuts into certain-length with conductive tape by 80% of battery leaf length, again as 125 * 125mm
2The battery sheet, cutoff length is 100mm, prepares stand-by.Because the width of front electrode grid line is generally less than 2mm, too narrow with the conductive tape adhesion width, be not easy on streamline, operate, and adhesive strength and contact resistance be difficult to guarantee, thus front electrode still with tradition carefully welding be welded to connect.After being welded to connect, thinner welding is guided to the back side of another battery sheet from the front, bond together with the back electrode of conductive tape welding and this battery sheet.With flexible material light pressure of adhesive tape smoothed.Length when preparing thin welding is as long as guarantee adhesion intensity, as 125 * 125mm
2The battery sheet, thin welding length can be 200mm.
Because the contact area of conductive tape and back electrode can be far longer than the area of back electrode grid line, as 125 * 125mm
2The battery sheet, conductive tape and cell back electrode contact surface be long-pending to be 3000mm
2, and the contact area of traditional welding is 400mm
2About, so the material thickness of conductive tape can suitably reduce, and as being thinned to 0.1mm from traditional 0.2mm, can reduce the fragment rate that the stress raisers of lamination process cause.
