Pond piece, i.e., upper and lower probe clamp cell piece in corresponding position jointly, and the electrode for contacting cell piece front and back respectively is surveyed
Examination.
However for the cell piece (such as battery used in imbrication component) of positive rear electrode dislocation, the method is but caught the flap and is seen
Elbow.This is because the positive rear electrode of battery cannot be contacted simultaneously if probe is arranged in same position up and down, tie test
Fruit is inaccurate and test result fluctuation is big；And if probe is arranged at positive rear electrode up and down, and the wind of fragment can be improved
Danger.
Common Curve guide impeller method is cell backside using all-metal platform test, and this method is testing positive backplane mistake
It is contacted while can both having guaranteed upper probe with front electrode and lower platform with rear electrode when the battery of position, greatly improves test knot
The accuracy of fruit, and reduce fragment risk.However, the method still remains two defects: first is that due to cell backside with it is whole
The contact of a metal platform, causes electric current directly to be collected by external circuit by back surface field, this and cell backside electric current in solar components
It is far from each other that the process that backplane is collected by external circuit again is flowed by back surface field, so that test result is distorted；Second is that testing two-sided electricity
Chi Shi causes test electric current bigger than normal since the back side is reflective.
In view of the above shortcomings, the designer, is actively subject to research and innovation, it can meet volume electricity production to found one kind
