Abstract
The utility model is realized in such a manner: an X type positive electrode structure used for a solar battery includes an auxiliary grating on the solar battery, main gratings, and a welding strip. The X type positive electrode structure used for the solar battery is characterized in that the auxiliary grating is arranged into a concentric-circle-liked shape, the auxiliary grating is provided with two crossed main gratings and the main gratings pass through a central area of the auxiliary grating. The two main gratings form an X shape, and one end of the main grating is connected with the welding strip. The advantages of the X type positive electrode structure used for the solar battery are that the structure is simple, so the conversion efficiency of the battery is improved, the production requirement of the printed electrode manufacturing is greatly lowered, and the influence caused by the grating breakage is obviously reduced; in addition, a device and a slurry do not need the upgrading, and in use, a short welding strip is enough to introduce the current, so the cost is saved.
Description
Technical field
The utility model relates to the front electrode structure that solar cell uses; Particularly a kind of X type positive electrode structure that is used for solar cell is to use screen printing technique that silver electrode is printed on solar cell surface special X type structure graph portrayal back on web plate of design.
Background technology
The Energy Conversion that shines upon earth surface is that electric energy surpasses 10
16KW, be whole world power consumption now hundreds of thousands doubly.That is to say that as long as the human minimum part of solar energy of utilizing just can solve the energy crisis in the whole world completely, so solar energy is considered to the optimum optimal alternative energy source of following human society.Solar cell can be an electric energy with solar energy converting directly, because energy source is approximate unlimited and free, noiselessness is pollution-free when changing simultaneously, makes it become a kind of outstanding green regenerative energy sources.
In order to collect and draw the electric current of solar cell conversion, just need be in the battery surface connection electrode.Method commonly used is the method with silk screen printing, is imprinted on battery front surface and back to metal electrode sizing by certain graphic style, makes it be cured as electrode and and battery formation ohmic contact through high temperature sintering then.Positive electrode is made up of two parts, and the main grid line directly links to each other with outside welding, and secondary grid line is more tiny, is used for collected current to be transferred to the main grid line.At present, traditional positive electrode structure is to be transferred to the main grid line perpendicular to secondary grid by many parallel secondary grid line collected currents, in use subsequently, can welding be welded on the main grid electric current is drawn.The problem that this kind positive electrode structure exists is for print request higher, will influence battery conversion efficiency in case produce the grid line crack conditions, in use needs long welding projected current simultaneously.In order to implement sustainable development energetically, make full use of this clean environment firendly energy of solar energy, be badly in need of existing positive electrode structure is improved, a kind of novel positive electrode structure that is used for solar cell is provided.
The utility model content
The utility model purpose is the deficiency that overcomes prior art, and a kind of novel positive electrode structure that is used for solar cell is provided.
The utility model is achieved in that a kind of X type positive electrode structure that is used for solar cell; Comprise: the secondary grid on the solar cell, the main grid and the welding that are connected with secondary grid; It is characterized in that: said secondary grid are arranged in " returning " font; On these pair grid, intersect and be provided with two main grids and this main grid central area through secondary grid, two main grids form " X " shapes, are connected with said welding at an end of main grid.
Said secondary grid are arranged in " returning " font and are made up of the secondary grid line of the identical concentric annular of many strips.
Said annular secondary grid line is square secondary grid line.
End at said main grid is provided with solder joint, and said welding is welded on this solder joint.
The utility model advantage is: simple in structure, improve battery conversion efficiency, and reduce greatly and make the production requirement of printing electrode; Reduce the influence that disconnected grid cause significantly, and need not equipment and slurry are upgraded, in use only need short welding simultaneously; Just the ability projected current is practiced thrift cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Because the positive electrode structure of solar cell exists print request higher, grid line is the situation of fracture easily, and for fear of this point, some producer begins constantly to improve equipment and slurry, but can not get expected effect.So traditional thinking is jumped out in this creation, on the structure of positive electrode, work hard.Shown in Figure 1 is a kind of novel X type positive electrode structure that is used for solar cell; Comprise: the secondary grid 2 on the solar cell, the main grid 1 that is connected with secondary grid and welding 3; It is characterized in that: said secondary grid are arranged in " returning " font; Should be made up of the secondary grid line of the identical concentric annular of many strips by " returning " font, this just is different from the parallel secondary grid structure of traditional positive electrode.Along with using metal paste more and more thicker in the printing process, disconnected grid phenomenon begins showed increased, has seriously influenced the raising of battery efficiency now.But the utility model is owing to used the secondary grid structure of this " returning " font connection, in case disconnected grid take place, electric current also can transfer to main grid through other secondary gate wires, can prevent effectively that the efficient that disconnected grid cause from reducing.In the utility model process, used automatic printing equipment of BACCINI and homemade handpress simultaneously, the battery sheet that obtains all has good conversion efficiency, and does not have disconnected grid influence on inspection.
On these pair grid, intersect and be provided with two main grids and this main grid central area through secondary grid, two main grids form " X " shapes, are connected with said welding at an end of main grid.
Said annular secondary grid line is square secondary grid line.
End at said main grid is provided with solder joint, in using in the later stage, directly welding is welded on the solder joint, and need not as traditional structure, welding to be welded on the positive electrode main grid.Therefore can practice thrift welding nearly 50% in producing in the later stage.
Manufacturing process is following: the special colloid of coating on silk screen, through steps such as drying, exposure, developments, the positive electrode structure is portrayed on the silk screen half tone.Use printing equipment, with metal paste according to the graphic printing on the silk screen half tone in solar cell surface.Use agglomerating plant that metal paste is sintered into metal electrode and and solar cell formation ohmic contact.In the later stage use, welding is welded on the solder joint of battery positive electrode, thereby electric current is drawn use.
Below only expressed the execution mode of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection range of the utility model.Therefore, the protection range of the utility model patent should be as the criterion with accompanying claims.
The utility model advantage is: simple in structure, improve battery conversion efficiency, and reduce greatly and make the production requirement of printing electrode; Reduce the influence that disconnected grid cause significantly, and need not equipment and slurry are upgraded, in use only need short welding simultaneously; Just the ability projected current is practiced thrift cost.
