Abstract
A screen printing crystalline silica solar energy cell positive silver screen printing plate is provided. The screen printing plate comprises a silicon chip, main grid wires, chamferings, and auxiliary grid wires, the silicon chip is provided with the main grid wires and the auxiliary grid wires, the main grid wires are vertical with the auxiliary grid wires, and the chamferings are arranged on the silicon chip. By adopting the special chamfering design, positive electrode grid wires can be effectively expanded on the silicon chip surface, the cover area is increased, the photoelectric current can be effectively collected, thus the efficiency of the cell sheet can be improved.
Description
Technical field
The utility model relates to the design of crystal silicon solar energy battery half tone, the positive silver-colored half tone of particularly a kind of screen printing crystalline silicon solar cell.
Background technology
Crystal silicon solar energy battery is the semiconductor device that conversion of solar energy is become electric energy, after solar battery sheet is carried out, use for photoelectric current is collected and is transported in the load, have an optimal design problem with high efficiency cell configuration design corresponding battery grid line structure.Grid line designs well, will make the series resistance minimum of battery, thereby makes power loss minimum, power output maximum, and this monomer solar cell to the output of large tracts of land power is particularly important.
The positive silver-colored half tone that uses adopts the secondary grid line pattern of wall scroll mostly at present, and photoelectric current is collected to the main grid line after collecting by secondary grid line.In actual production, tend to occur secondary grid line printing condition of poor and be void situation such as break, bite, make photoelectric current can not arrive the main grid line, thereby influence the conversion efficiency of solar cell.
The utility model content
The purpose of this utility model is in order to provide a kind of screen printing crystalline silicon solar cell positive silver-colored half tone, to solve the shortcoming in the background technology.
The positive silver-colored half tone of screen printing crystalline silicon solar cell comprises: silicon chip, main grid line, chamfering, secondary grid line, described silicon chip are provided with main grid line and secondary grid line, and described main grid line is provided with secondary grid line is vertical, is provided with chamfering on described silicon chip.
Beneficial effect:
The special chamfer design of the utility model can effectively be expanded the front electrode grid line at silicon chip surface, increases area coverage, photoelectric current is carried out effective collection, thereby improved the efficient of battery sheet.
