Recommended process

Silicon substrate: HJT solar cells;

Stirring: Manually stir for 5-10 minutes before use; Use centrifugal stirring equipment at a speed of 400-600 rpm,

stirring for 90-180 seconds. It is recommended that the slurry does not become hot (if it becomes hot after stirring, it is

recommended to reduce the speed or time, and let the slurry stand for 2-4 hours before use). Before use, manually stir it

appropriately;

Printing: 430-520 mesh screen;

Drying: The oven is set at a temperature of 150-170 ℃ for 30-120 seconds;

Curing: Oven temperature 160-200 ℃, 5-20 minutes;

Warranty: The product meets the company's testing standards before leaving the factory;

Packaging: To ensure the performance of the silver paste, pack 2kg of silver paste in a 610ml can and wrap tape

around the joint between the can body and the lid, and affix labels for identification;

Storage: Sealed storage, temperature between -30~-5 degrees Celsius, in a dry environment; Before opening the

tank, the slurry should be at the same temperature as the environment (to avoid low slurry temperature and

condensation); Avoid direct sunlight; (You can refer to the workshop temperature and humidity standards for warehouse

storage)

Validity period: Six months from the production date;
