The market scale of HJT low-temperature silver paste continues to expand, and Suzhou GoodTech becomes the leading enterprise in my country.

HJT battery, also known as heterojunction battery, refers to an N-type battery formed from amorphous silicon and crystalline silicon materials. HJT low-temperature silver paste is one of the main raw materials of HJT batteries. It refers to a thick film conductor paste produced with ultra-fine flake silver powder as the conductive phase in a relatively low temperature environment of 200-250°C. HJT low-temperature silver paste has the advantages of fast printing speed, strong welding pull force, good continuous printing performance, and low resistivity.

The raw materials of HJT low-temperature silver paste include additives, adhesives, silver powder, organic raw materials, glass powder, etc., among which silver powder accounts for the main production cost. At present, my country’s silver powder market has a low level of localization and its products are highly dependent on imports. Japan is my country’s main importer of silver powder, accounting for nearly 90%. In recent years, the independent research and development capabilities of Chinese enterprises and scientific research institutions have continued to improve, and Dongfang Electric Group has mature silver powder production capabilities. The accelerated localization of silver powder in my country will provide favorable conditions for the development of the HJT low-temperature silver paste industry.

The HJT low-temperature silver paste industry has high technical barriers, and there are problems such as high silver consumption, low production efficiency, and high production costs. The main production process of HJT low-temperature silver paste includes ingredients, mixing, stirring, three-roller mixing, filtration and other links. Three-roller mixing plays a decisive role in the fineness, rheological properties, viscosity, etc. of HJT low-temperature silver paste, and is a key link in the production of HJT low-temperature silver paste. In the future, with the rapid development of my country’s HJT low-temperature silver paste production technology, its manufacturing costs are expected to be reduced, and its production efficiency will be further improved by then.

According to the “2023-2028 China HJT Low Temperature Silver Paste Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , HJT batteries are the only demand side for HJT low-temperature silver paste. HJT batteries are mainly used in the photovoltaic field. In recent years, driven by national policy support and market demand, my country’s HJT battery production capacity has rapidly expanded, and shipments have continued to grow. In 2022, my country’s HJT battery shipments will reach 13GW, a year-on-year increase of 213.5%. Benefiting from the increasing prosperity of the HJT battery industry, the HJT low-temperature silver paste market continues to expand, reaching nearly 11 billion yuan in 2022.

The main players in my country’s HJT low-temperature silver paste market include Wuxi Dike Electronic Materials Co., Ltd., Suzhou Goodtech Electronics Co., Ltd., Guangzhou Polymer New Material Technology Co., Ltd., etc. Suzhou Technetium is the leading HJT low-temperature silver paste company in my country, accounting for nearly 50% of the market share. According to the financial report of Suzhou Goodtech Enterprise, the company’s HJT low-temperature silver paste shipments reached 5.1 tons in 2021, ranking first in my country.

Industry analysts said that as one of the main raw materials for HJT batteries, HJT low-temperature silver paste has high technical barriers and my country’s products mainly rely on imports. . In recent years, with the in-depth research and technological advancement of local enterprises, the localization process of HJT low-temperature silver paste has accelerated in my country, and production efficiency has continued to improve. It is expected that in the future, driven by market demand, the development trend of my country’s HJT low-temperature silver paste industry will continue to improve.
