The utility model discloses a more conventional battery of electrode coverage area has the reduction by a wide margin, and the coverage area of back electrode and positive electrode all reduces to some extent, and the silver thick liquid of corresponding consumption also reduces to some extent, has reduced the unit consumption of silver thick liquid by a wide margin, has saved manufacturing cost.
Description
Technical field
The utility model relates to a kind of solar panel, especially relates to a kind of three gate electrodes 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 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.Battery electrode is minimum with the battery total-power loss, designs according to predefined battery parameter value.But existing electrode coverage is long-pending 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 long-pending big for the electrode coverage that solves present solar panel; Silver slurry unit consumption is high; The production cost problem of higher; A kind of three gate electrodes 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; Three main grid lines 3 of positive electrode 2 are segmented into discontinuous.
Three gate electrodes of the utility model solar cell, said back electrode 1 is divided into the 4-10 section.
Three gate electrodes of the utility model solar cell, said back electrode 1 every segment length can be identical, also can be different.
Three gate electrodes of the utility model solar cell, said back electrode 1 every segment length is 5-20mm.
Three gate electrodes of the utility model solar cell, said positive electrode main grid line 3 is divided into the 4-15 section.
Three gate electrodes 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.
Three gate electrodes 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 electrode coverage of the utility model solar panel is long-pending to have minimizing significantly than conventional batteries; The back electrode area coverage reduces 20%; The area coverage of positive electrode reduces 25%; The silver of corresponding consumption is starched also to have and has been reduced 20% and 25% respectively, has reduced the unit consumption of silver-colored slurry significantly, has saved production cost.
Description of drawings
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
Disclosed all characteristics in this specification, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.
Disclosed arbitrary characteristic in this specification (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
Three gate electrodes of the utility model solar cell comprise three grid back electrodes, positive electrode, and back electrode 1 is discontinuous, segmentation, number of fragments can be the 4-10 section, and every segment length can be the same or different, and length is 5-20mm; Positive electrode main grid line 3 is discontinuous, segmentation, and number of fragments can be the 4-15 section, the distance between every section can be identical also can be different, the intersegmental 8-20mm that is of a size of.
The utility model is not limited to aforesaid embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
