Description

Technical Field

[0001] The utility model relates to the field of battery sheet production, in particular to a non-printed battery sheet buffer device. Background Art

[0002] TOPCon is a tunneling oxide passivation contact solar cell technology based on the principle of selective carriers. Its cell structure is an N-type silicon substrate cell. An ultra-thin silicon oxide layer is prepared on the back of the cell, and then a thin layer of doped silicon is deposited. The two together form a passivation contact structure, which effectively reduces surface recombination and metal contact recombination, and provides greater room for further improvement of the conversion efficiency of N-PERT cells. Its production process includes texturing, boron diffusion, BSG removal + alkaline polishing, deposition of amorphous silicon, RCA, ALD, front and back coating, and metallization. The metallization process is to print silver paste electrodes on the surface of the cell, and sinter them in a sintering furnace to form a good ohmic contact between the metal electrode and the silicon wafer. Currently, in the production line, AOI is used to inspect the cell after each printing.

After the non-printing films are lifted up, the machine will alarm and stop running, and the non-printing films need to be removed manually. This process will seriously affect the production, and in the process of taking the films, it is easy to cause fragments artificially, which greatly increases the fragmentation rate.
