Embodiment Construction
[0026] Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.
[0027] Such as image 3 , 4 Shown, a kind of rapid detection method of MWT solar cell, comprises the following steps:
[0028] 1. Visual inspection
[0029] Place the MWT solar cell face up under the light, and check whether the negative pole 2 hole of the MWT solar cell is transparent. If there is light transmission through the small holes, it indicates that the filling of the plugging slurry at the small holes of the negative electrode is insufficient, and the MWT solar cell may have a proble...

The invention discloses a quick detection method of an MWT solar battery. The quick detection method comprises the following steps of 1, performing appearance inspection: inspecting whether negative electrode point small holes of the MWT solar battery are light transmitting or not; 2, performing resistance value examination between negative electrode points: measuring the resistance value betweenany two negative electrode points; and 3, performing resistance value examination between positive electrode points: measuring the resistance value between any two positive electrode points. The quickdetection method is low in environment and tool requirements; the operating method can be learned simply and conveniently; and poor contact between positive silver and plugging paste and between backsilver and an aluminum back field of the MWT solar battery can be found conveniently and quickly, so that screening out of the MWT solar battery with the abovementioned defects in the production process can be facilitated.
Description
technical field [0001] The invention relates to a rapid detection method of a MWT solar cell, specifically by checking the resistance value between different electrode points of the MWT solar cell, so as to quickly determine whether the solar cell has defects. The invention belongs to the technical field of MWT solar cell processing in the photovoltaic industry . Background technique [0002] MWT photovoltaic modules are composed of glass, packaging materials (such as: EVA film), MWT solar cells, conductive glue, GPS, and integrated conductive backplanes under certain temperature, time and pressure, through the curing and bonding of packaging materials (EVA film). made. [0003] Since MWT solar cells are the core raw materials of MWT photovoltaic modules, various defects will occur during the production process. If the defective MWT solar cells cannot be screened out in time, various defects will also occur in MWT photovoltaic modules. [0004] For MWT solar cells, the mos...
