Abstract
The purpose of this utility model is to provide a kind of silicon based cells piece laser passivating device the phenomenon of short circuit, including laser, infrared inductor, apparatus of oxygen supply and conveyer easily occur for solving silicon based cells piece；The apparatus of oxygen supply is located at the both sides of laser, and conveyer is located at below laser, and the utility model controls the unlatching of apparatus of oxygen supply and laser, good passivation effect by infrared inductor, while saving the energy, passivation efficiency is high.
Description
Technical field
The utility model belongs to field of new energy technologies, more particularly to solar battery sheet, particularly relates to one kind
Silica-based solar cell piece laser passivating device.
Background technology
At present in silica-based solar cell piece production link, in order to avoid produced by silica-based solar cell piece p-n junction
Light induced electron flows to the back side of p-n junction along edge, prevents from causing the short circuit of silicon based cells piece, many cell piece factories adopt commercial city
Etched with plasma periphery.Laser is because with small volume, lightweight, efficiency high, energy consumption are small, long lifespan the advantages of and with
The cost of laser constantly declines, and laser is widely used.
The present invention is passivated mode using laser, carries out edge passivation to cell piece in oxygen-enriched environment, and passivation efficiency is high, right
The damage of silicon based cells piece is small.
The content of the invention
To solve the above problems, in view of this, the utility model provides a kind of passivating device of silicon based cells piece, including swashs
Light device, infrared inductor, apparatus of oxygen supply and conveyer；The apparatus of oxygen supply is located at the both sides of laser, conveyer
Below laser.
Infrared inductor is mounted on the outside of the apparatus of oxygen supply, its role is to：Detect the position of cell piece.
The infrared inductor I transfers signals to apparatus of oxygen supply and laser, control apparatus of oxygen supply and laser
Open.
The infrared inductorTransfer signals to apparatus of oxygen supply and laser, control apparatus of oxygen supply and laser
Close.
Cell piece is placed in frock clamp by the conveyer, and vertical direction transmission passes through laser works area.
The laser shape that the laser is sent is linear, and width is 1-5cm.
The utility model has the advantage that：Using laser, cell piece is passivated under excess oxygen, is passivated
Effect is good, and passivation efficiency is high；The unlatching of apparatus of oxygen supply and laser is controlled by infrared inductor, the energy is saved, it is to avoid wasted
Phenomenon.

Embodiment
Below in conjunction with the accompanying drawings 1 and accompanying drawing 2 the utility model is further described.
A kind of passivating device of silicon based cells piece, including laser 1, apparatus of oxygen supply 2, infrared inductor I 3 and infrared
Induction installation4, and conveyer 5；The apparatus of oxygen supply 2 is located at the both sides of laser 1, and conveyer 5 is located at laser
Lower section.
The outside of the apparatus of oxygen supply 2 is mounted on infrared inductor.
The infrared inductor I 3 transfers signals to apparatus of oxygen supply and laser, control apparatus of oxygen supply and laser
Unlatching.
The infrared inductor4 transfer signals to apparatus of oxygen supply and laser, control apparatus of oxygen supply and laser
Closing.
By the cell piece 6 being put into frock clamp, transmission passes through laser works area to the conveyer 5 vertically.
The frock clamp ensures cell piece into vertical state.
The laser shape that the laser 1 is sent is linear, and width is 1-5cm.
The operation principle of the present apparatus：
Silicon based cells piece is sent into by working region by conveyer 5, oxygen is provided by apparatus of oxygen supply 2 and 3, in laser
Silicon based cells piece surrounding side is passivated under the linear laser effect that device 1 is produced.When the front end of cell piece 6 placed vertically is by red
During outer induction installation I 3, apparatus of oxygen supply starts oxygen supply, while laser 1 is started working.When the tail end of cell piece 6 passes through infrared sense
Answer deviceWhen 4, portion support device oxygen feeding stop, while laser 1 is stopped.
Certainly, the above is only preferred embodiment of the present utility model, it is impossible to be considered as being used to limit to utility model
Scope of embodiments.The utility model is also not limited to the example above, and those skilled in the art are in this practicality
The equivalent change made in new essential scope and improvement etc., all should belong to the utility model patent covering scope.
