technical field:
The present invention relates to a kind of fast detecting positive silver grating line slurry and the ageing-resistant method of welding, be particularly suitable for the detection field of the high-temp resisting high-humidity resisting environment of solar battery sheet.
background technology:
current solar cell factory all must by a series of strict environmental standard burn-in test before sale assembly, and wherein a test is the test under hot and humid lower environment, and its standard is relative temperature 85
oc and relative humidity 85%, the testing time is 1000h.But the research and development of such detection for solar cell and the use too time-consuming of new anode sizing agent, research before shows, to solar battery sheet and welding thereof carry out hot and humid under burn-in test just can the ageing properties of prediction component to a certain extent, and provide important reference to the research and development of anode sizing agent and welding, so at present industry is badly in need of a kind of fast detecting positive silver grating line slurry and the ageing-resistant method of welding.
summary of the invention:
Technical problem to be solved by this invention is, provide a kind of can fast detecting positive silver grating line slurry and the ageing-resistant method of welding.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of fast detecting positive silver grating line slurry and the ageing-resistant method of welding, comprise the following steps: a, surface at solar battery sheet, be printed with positive silver paste, and form multiple grid line structure; B, on grid line structure, be welded with tin-coated copper strip, the temperature of welding is 350
oc, and ensure do not have rosin joint phenomenon to occur; C, the solar battery sheet welded is carried out the test of first time electric performance test, particularly series resistance, electroluminescence is tested; D, the solar battery sheet tested to be positioned over temperature be 100 degree of-120 degree, and humidity is in 85%-100% environment, and standing time is 24h-96h; After e, placement, taken out by solar battery sheet, carry out the test of second time electric performance test, particularly series resistance, electroluminescence is tested; F, compare twice test data, particularly compare the changing value of series resistance, changing value is less shows that the ability of solar battery sheet high-temp resisting high-humidity resisting environment is stronger, show positive silver paste used and welding ageing-resistant performance more excellent.
Compared with prior art, usefulness of the present invention is: this fast detecting positive silver grating line slurry and the ageing-resistant method of welding, the ageing-resistant degree of positive silver grating line slurry and welding can be detected fast, thus to a certain extent can the ageing properties of prediction component, and provide important reference information to the quick research and development of anode sizing agent and welding.
