Abstract
The utility model discloses a pattern of two gate electrodes of a solar cell, comprising a back electrode (1) and a positive electrode (2) that are arranged on a cell plate. The back electrode (1) is segmented discontinuously and two main grid lines (3) of the positive electrode (2) are segmented discontinuously. The electrode pattern provided by the utility model is reduced to a great extent in cover area compared with conventional pattern cells. The cover area of the back and positive electrodes is reduced so that silver paste consumed is reduced correspondingly, thereby reducing the unit consumption of the silver paste to a great extent and saving the production cost.
Description
Technical field
The utility model relates to a kind of solar panel, especially relates to a kind of two gate electrode figures of solar cell.
Background technology
Solar cell is the semiconductor device that solar energy converting is become electric energy.Battery electrode is the important component part of battery, and it is responsible for causing outside batteries to the photogenerated current in the cell body; Simultaneously when battery is made assembly and welding rod play conduction current.
Solar cel electrode is divided into positive electrode, back electrode.Main grid line, the back electrode of the positive electrode figure of most of two main grids that use are continuous in the industry at present, use the mode of silk screen printing that conductive silver paste is printed on the battery usually, pass through high temperature sintering again, are used as electrode with this.The figure of battery electrode is minimum with the battery total-power loss, designs according to predefined battery parameter value.But existing electrode pattern area coverage is big, and the silver that causes printing is starched the unit consumption height, because the silver slurry costs an arm and a leg, causes production cost higher.
The utility model content
The utility model is big for the electrode pattern area coverage that solves present solar panel; Silver slurry unit consumption is high; The production cost problem of higher; A kind of two gate electrode figures of solar cell are provided for this reason, have comprised the back electrode 1 and positive electrode 2 that are arranged on the cell panel, said back electrode 1 is segmented into discontinuous; Two main grid lines 3 of positive electrode 2 are segmented into discontinuous.
Two gate electrode figures of the utility model solar cell, said back electrode 1 is divided into the 4-10 section.
Two gate electrode figures of the utility model solar cell, said back electrode 1 every segment length can be identical, also can be different.
Two gate electrode figures of the utility model solar cell, said back electrode 1 every segment length is 5-20mm.
Two gate electrode figures of the utility model solar cell, said positive electrode main grid line 3 is divided into the 4-15 section.
Two gate electrode figures of the utility model solar cell, the every intersegmental distance of said positive electrode main grid line 3 can be identical, also can be different.
Two gate electrode figures of the utility model solar cell, the every intersegmental distance of said positive electrode main grid line 3 is 8-20cm.
The beneficial effect of the utility model:
The more conventional figure battery of the electrode pattern area coverage of the utility model solar panel has minimizing significantly; The back electrode area coverage reduces 50%; The area coverage of positive electrode reduces 35%; The silver of corresponding consumption is starched also to have and has been reduced 50% and 35% respectively, has reduced the unit consumption of silver-colored slurry significantly, has saved production cost.
Figure of description
The utility model will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the positive electrode sketch map of the utility model;
Fig. 2 is the back electrode sketch map of the utility model.
Embodiment
