On August 1, SZYJ Electronic Materials Technology Group, a leading manufacturer of HIT silver paste, front electrode silver paste, and crystalline silicon solar front electrode silver paste, launched a new electronic silver paste product:
The latest product HJT silver paste has been put into mass production, and the order delivery has been achieved
SZYJ focuses on the paste industry in the electronic materials industry. The downstream application field of its products is mainly the solar photovoltaic industry. Its main product is front silver paste. The company's technology research and development capabilities, its own intellectual property rights, front silver paste product performance and market share The rate ranks among the top domestic counterparts. In addition to the mature product front silver paste, it has gradually entered the promotion of back silver paste products. The latest product HJT silver paste has been put into mass production, and orders have been delivered. It is one of the few domestic pastes that have successfully developed independently and have truly achieved mass production and sales. enterprise.
Comparing the differences in process and technical parameters between high-temperature silver paste and low-temperature silver paste, SZYJ said that the current mainstream products in the market are gradually developing towards PERC battery silver paste and N-type TOPCON battery silver paste, all using high-temperature sintering processes with a temperature of 700 Between ℃ and 800℃, the battery conversion efficiency is about 23%, and the unit consumption of PERC front silver paste is about 80mg/piece.
In contrast, the sintering temperature of HJT low-temperature silver paste is 200℃-300℃, and the positive silver and back silver consume the same type of silver paste. The unit consumption of 9BB battery silver paste is about 180mg/piece-220mg/piece, HJT silver The demand for pulp will gradually increase.
The design capacity of SZYJ's new plant is 1,000 tons/year, and the planned annual capacity of the first phase is 500 tons, of which the equipment capacity relocated from the old site is 350 tons/year.
The characteristics of silver paste products make silver paste belong to the asset-light industry, and its fixed asset investment accounts for a small proportion. Therefore, the production capacity of positive silver and back silver can be switched in time with orders, without technical barriers, equipment, and site restrictions.
At the same time, the core technology of silver paste products is the formula, and the material cost of more than 90% is precious metal silver powder. The advantage of SZYJ lies in its own ability to continuously break through technological innovation. The raw materials are domestic silver powder or imported silver powder requested by customers. , Cooperate with client product requirements and printing equipment and other processes for research and development, while ensuring quality, it has a certain cost advantage. It provides customized services to customers and provides various specifications and different formulations of slurry products.
