Description

A kind of quick determination method of MWT solar cells
Technical field
The present invention relates to a kind of quick determination method of MWT solar cells, particular by inspection MWT solar cells Resistance value between Different electrodes point, so as to quickly judge that this solar cell whether there is defect, the invention belongs to photovoltaic row Industry MWT solar cell processing technique fields.
Background technology
MWT photovoltaic modulies by glass, encapsulating material (such as:EVA adhesive film), it is MWT solar cells, conducting resinl, GPS, integrated Conductive backings are bonded under certain temperature, time and pressure by the curing of encapsulating material (EVA adhesive film).
Since MWT solar cells are the core starting materials of MWT photovoltaic modulies, itself can produce in the production process respectively The bad of various kinds is planted, if undesirable MWT solar cells cannot be filtered out in time, it will cause MWT photovoltaic modulies also to occur Each badness.
For MWT solar cells, most common bad have the following two kinds:
A) loose contact between the positive silver and blocking slurry of MWT solar cells, causes battery cathode point resistance value higher. If such undesirable MWT solar cells cannot filter out, it may result in MWT photovoltaic modulies and occur such as Fig. 1 when EL is detected It is bad shown in middle circle.
B) loose contact between the back of the body silver of MWT solar cells and Al-BSF, causes anode point resistance value higher.Such as The such undesirable MWT solar cells of fruit cannot filter out, and may result in MWT photovoltaic modulies and occur when EL is detected as in Fig. 2 It is bad shown in circle.
So the detection method of above-mentioned loose contact can be rapidly filtered out, the matter to improving MWT solar cells Amount, reduces the adverse effect to follow-up MWT components production, is of great significance with regard to tool.
The present invention is exactly a kind of can quickly to be detected between the positive silver of MWT solar cells and blocking slurry, carry on the back silver and aluminium The method of loose contact between back surface field.
The content of the invention
Goal of the invention:Between the positive silver and blocking slurry that easily occur in process of production for MWT solar cells, carry on the back The problem of loose contact between silver and Al-BSF, the present invention provides a kind of method for quickly detecting of MWT solar cells.Its mesh Be can quickly and easily find MWT solar cells it is positive silver block slurry between, the back of the body silver and Al-BSF between Loose contact, the MWT solar cells with drawbacks described above for being conducive in process of production to occur screen, avoid by MWT solar cells with drawbacks described above flow to next process, so that the quality of MWT solar cells is improved, reduction pair The adverse effect of follow-up MWT components production.
Technical solution:A kind of quick determination method of MWT solar cells, comprises the following steps:
1. visual examination
Check MWT solar cells anode point aperture whether printing opacity;If there are printing opacity aperture phenomenon, show anode point Block that filled therewith is insufficient, this MWT solar cell carries out the next item down inspection there may be the problem of loose contact at aperture Survey;
2. the resistance value inspection between anode point
In the optional two anode point in the back side of MWT solar cells, with measuring instrument (such as:Universal meter, etc.) measurement two Resistance value between anode point, if resistance value is more than preset value, shows wherein with the presence of anode point loose contact Problem;
3. the resistance value inspection between positive limit
In the optional two positive limits in the back side of MWT solar cells, with measuring instrument (such as:Universal meter, etc.) measurement two Resistance value between positive limit, if resistance value is more than preset value, shows wherein have one just to be deposited between limit and Al-BSF The loose contact the problem of.
Beneficial effect:The quick determination method of MWT solar cells provided by the present invention, to environment and tool demands Low, operating method is simple and convenient and easy to study, can quickly and easily find between the positive silver of MWT solar cells and blocking slurry, back of the body silver Loose contact between Al-BSF, is conducive to the MWT solar cells with drawbacks described above that will occur in process of production Screen.
