HJT low-temperature conductive silver paste containing silver nano short rods and preparation method of HJT low-temperature conductive silver paste

The invention discloses an HJT low-temperature conductive silver paste containing a silver nano short rod and a preparation method thereof, including a silver nano short rod suitable for the HJT low-temperature conductive silver paste and a preparation method thereof, and a use method of the silver nano short rod in the HJT silver paste, when the silver nano short rod is applied to the HJT low-temperature conductive silver paste, the silver nano short rod can generate excellent ohmic contact performance; when the silver nano short rod is added into HJT low-temperature curing conductive silver paste, the resistance of a silver grid line can be remarkably reduced under the condition of the same silver content (namely, the electricity of the silver grid line is smaller than or equal to 4 * 10 <-6 > omega.cm), the printing performance and the welding tension are not affected, high conductivity and excellent photoelectric conversion efficiency are shown, and therefore the silver nano short rod ...
