AT series alkali polishing additives are easy to clean and leave no residue
Good flatness is beneficial to the uniformity of the back passivation film
Applicable to ozone oxidation, thermal oxygen oxidation, and tube oxygen oxidation processes
Conventional PERC and TOPCON battery manufacturing alkaline polishing process
Efficiency increased by about 0.02-0.03%
Mainly due to the advantage of opening voltage current
In terms of electrical performance, the opening voltage
The filling gain is obvious
Improve the reflectivity of the back surface and increase the reflectivity of long-wavelength light inside the pyramid
