Technical field
The utility model relates to a kind of pick-up unit, relates in particular to the infrared defect detecting device of a kind of IBC solar cell.
Background technology
IBC back of the body junction battery front is completely unobstructed, and the area coverage of contact electrode has almost reached 1/2nd of back of the body surface, greatly reduces resistance in series, adopts the photovoltaic panel conversion efficiency of IBC back of the body junction battery will substantially exceed conventional solar cell photovoltaic panel.IBC back of the body junction battery, as a kind of novel efficient solar battery, has great application prospect.But for the pick-up unit of IBC back of the body connection solar cell, still there is blank at present.Wherein most important detection means---infrared defects detection is not also applied in the detection of IBC solar cell.Conventional infrared defect detecting device is used probe row pressure on the main grid line of solar cell, and uses conductive material contact at the back side of battery, connects the both positive and negative polarity of solar cell, comes cell piece energising test.
The electrode form of IBC solar cell is different from conventional solar cell, and its both positive and negative polarity is evenly distributed on the back side of IBC solar cell piece, and front does not exist distribution of electrodes, can not adopt the mode that powers up of conventional batteries.Because IBC back of solar cell has aluminium paste, cover, can only carry out in the front of cell piece the imaging test of infrared defect, this just needs special cell piece mounting table to guarantee the unobstructed of light path.
Utility model content
The purpose of this utility model, exactly in order to address the above problem, provides a kind of novel infrared defect detecting device of IBC solar cell.
In order to achieve the above object, the utility model has adopted following technical scheme: the infrared defect detecting device of a kind of IBC solar cell, comprises test darkroom, transparent cell piece mounting table, automatic power-up device, infrared imaging mechanism, constant current source and computing machine; Test darkroom is provided with the turnover slotted eye of transparent cell piece mounting table, transparent cell piece mounting table and described slotted eye are movably connected, automatically power-up device is arranged on transparent cell piece mounting table, infrared imaging mechanism is arranged on the bottom in test darkroom, constant current source is electrically connected with automatic power-up device, and computing machine and infrared imaging mechanism telecom-connect.
Described infrared imaging mechanism front end is provided with optical filter.
Described IBC solar cell is IBC back of the body connection solar cell.
The infrared defect detecting device of IBC solar cell of the present utility model is used constant current source to pass through automatic power-up device IBC solar cell is switched in test darkroom, and use infrared imaging mechanism to gather the luminous signal of the specific wavelength that IBC solar cell sends, finally in computing machine, form image.Can fast detecting go out IBC solar cell hiddenly split, the inherent vice such as fragment, disconnected grid.

IBC solar cell in the utility model is IBC back of the body connection solar cell.
The method step that adopts the utility model IBC solar cell infrared defect detecting device to carry out infrared defect test to IBC solar cell is can accompanying drawings as follows:
A, IBC solar cell 8 is faced down and is placed on transparent cell piece mounting table 2;
B, press device button, transparent cell piece mounting table enters into test darkroom 1 automatically;
C, infrared imaging mechanism 4 are fixed on test bottom, darkroom, are connected with computing machine 6 electric signal, and infrared imaging mechanism is just to IBC solar cell central point;
D, control automatic power-up device 3 and connect IBC cell piece both positive and negative polarity, the output current intensity of constant current source 5 is set, to the energising of IBC solar cell, excite IBC solar cell to send the luminous signal of specific wavelength;
E, by computer software, operate infrared imaging mechanism 4, infrared imaging mechanism 4 forms image transmitting to computing machine by luminous signal;
F, close constant current source;
G, the image gathering by infrared imaging mechanism 4, analyze IBC solar cell inherent vice;
H, taking-up IBC solar cell, prepare lower a slice battery testing.
The infrared defect detecting device of IBC solar cell of the present utility model adopts transparent cell piece mounting table, conveniently infrared defect test is carried out in solar cell front, and power-up device adapts to the electrode feature of IBC cell piece automatically, and pressure is evenly suitable.It is fast that device has test speed, easy to operate, the low advantage and disadvantage that waits of fragment rate.
