Abstract
The utility model discloses a novel laser scribing structure of a laminated silicon-based thin film solar cell. The laminated silicon-based thin film solar cell consists of a back electrode layer, a silicon absorption layer, a front electrode layer and glass and finishes laser scribing to form a solar cell module; a bus bar is welded and led out at one side of the module; and a cell structure in the module is converted, thereby bringing convenience for leading out of the bus bar, reducing the number of the bus bars used in the module and being conductive to reducing of the defects in the laminated process by the assembly process. At the same welding spot density, the number of welding points in the assembly is reduced; and meanwhile, the novel laser scribing structure facilitates the reduction of the cost.
Description
Technical field
The utility model belongs to technical field of solar batteries, particularly a kind of new laminated silicon-base film solar battery laser line structure.
Background technology
Solar cell is a kind of semiconductor photoelectronic device, and it utilizes the photovoltaic effect of device directly to convert solar energy to electric energy, does not have any pollution, is a kind of optimal clean regenerative resource.
A kind of as solar cell, the laminated silicon-base film solar cell is because the low cost of its production, low energy consumption, pollution-free and itself is with respect to the high conversion efficiency and the low decay property of other thin-film solar cells, by a large amount of manufacturings and application.Comprise amorphous silicon/microcrystal silicon structure, amorphous silicon/amorphous silicon germanium/microcrystal silicon structure, amorphous silicon/amorphous silicon germanium/structures such as amorphous silicon germanium.
The design of large tracts of land laminated silicon-base film battery mainly is the design that is used for the power station at present, when the laminated silicon-base film assembly prepares, in order to improve the assembly whole efficiency, whole face is used laser rules, whole rete is cut, in the middle of then busbar being guided into, cause the central authorities of both positive and negative polarity like this at assembly, by both sides welding edge busbar, by horizontal busbar electric current is guided into the central authorities of assembly again, the bonding terminal box in the positive middle part of assembly more at last, the position of terminal box also just can only be placed on the middle of establishment like this, and this kind design is unfavorable for that bulk silicon base film assembly is at BIPV (BuildingIntegrated Photovoltaic, BIPV) utilization in, when directly this design being applied to BIPV, can bring a lot of inconvenience, be unfavorable for the utilization of laminated silicon-base film solar cell in BIPV.
The utility model content
The purpose of this utility model is to overcome weak point of the prior art, a kind of new laminated silicon-base film solar battery laser line structure is provided, can be at the new laminated silicon-base film solar battery structure of large tracts of land utilization silica-base film assembly among the BIPV (Building IntegratedPhotovoltaic, BIPV).
To achieve these goals, the utility model is achieved in that
A kind of new laminated silicon-base film solar battery laser line structure, the laminated silicon-base film solar panel is made up of for four layers dorsum electrode layer, silicon absorbed layer, preceding electrode layer and glass, it is characterized in that, by laser scribe process, the preceding electrode layer of laminated silicon-base film solar panel, silicon absorbed layer and dorsum electrode layer were divided by laser respectively to the silicon absorbed layer; Busbar welds both positive and negative polarity mutually and draws successively at the homonymy of laminated silicon-base film solar panel.
A kind of new laminated silicon-base film solar battery laser line structure described in the utility model, electrode layer is TCO film (transparentconductiveoxide, a transparent conductive oxide) before it is characterized in that.
A kind of new laminated silicon-base film solar battery laser line structure described in the utility model is characterized in that the both positive and negative polarity of laminated silicon-base film solar panel is in the same side.
A kind of new laminated silicon-base film solar battery laser line structure described in the utility model is characterized in that the laminated silicon-base film solar panel can be divided into the different pattern type by laser scribe process.
The position that the advantage of a kind of new laminated silicon-base film solar battery laser line structure described in the utility model is terminal box by the position change of the middle of assembly to marginal position, help the large tracts of land utilization of laminated silicon-base film solar cell in BIPV, on the other hand, reduced the quantity of using busbar in the assembly, help on component process, reducing the defective that produces in the lamination, under identical solder joint density, reduced the solder joint number on the assembly, and then its defective workmanship falls, simultaneously, also help reducing cost.
Description of drawings
The structural representation of a kind of new laminated silicon-base film solar battery laser line of Fig. 1 structure.
Among the figure: 1, glass; 2, preceding electrode layer; 3, silicon absorbed layer; 4, dorsum electrode layer.
Embodiment
As shown in Figure 1, the laminated silicon-base film solar panel is made up of for 1 four layers dorsum electrode layer 4, silicon absorbed layer 3, preceding electrode layer 2 and glass, the laminated silicon-base film solar panel is placed in the laser scribing instrument, the laminated silicon-base film solar panel is rule, as shown in Figure 1, P1, P2, P3 are respectively three the line positions of laser scribing instrument to the laminated silicon-base film solar panel.
The both positive and negative polarity of laminated silicon-base film solar panel becomes the same side by the two ends of assembly.
Use busbar that the both positive and negative polarity of laminated silicon-base film solar cell panel assembly is welded mutually successively and draws, special BIPV terminal box is installed then, get final product large-area use in BIPV.
