High-temperature silver paste (high-temperature sintering silver paste) can be used to produce TOPCon batteries. High-temperature front-side silver paste is its representative product.

According to the different sintering temperatures of silver paste, photovoltaic silver paste can be divided into two types: low-temperature silver paste and high-temperature silver paste. High-temperature silver paste is also called high-temperature sintering silver paste, which refers to photovoltaic silver paste with a sintering temperature above 500°C. High-temperature silver paste has the advantages of high temperature resistance, good electrical conductivity, corrosion resistance, strong adhesion, and good thermal conductivity. It is widely used in the production process of TOPCon batteries, BSF batteries, IBC batteries, and PERC batteries.

The upstream of the high-temperature silver paste industry chain supplies raw materials, including organic solvents, glass oxides, silver powder, etc. Silver powder plays a decisive role in the conductivity of high-temperature silver paste, accounting for nearly 90% of its production cost. Photovoltaic silver powder is a strategic emerging industry in my country, and its production is difficult. There is still a certain gap between the technical level of Chinese enterprises and overseas developed countries, resulting in long-term dependence on imports for demand. In the future, with the improvement of technological maturity, the localization process of my country’s photovoltaic silver powder market is expected to accelerate, and the production cost of high-temperature silver paste will be further reduced.

The midstream of the high-temperature silver paste industry chain is product manufacturing. High-temperature front silver paste and high-temperature back silver paste are representative products of high-temperature silver paste. High-temperature front-side silver paste refers to the photovoltaic silver paste coated on the front side of photovoltaic cells. It has the advantages of corrosion resistance and good conductivity, and can improve the photoelectric conversion efficiency of the cells. In recent years, the development of the high-temperature front silver paste industry has accelerated, and its market demand has become increasingly strong. According to the “2023-2028 China High-Temperature Silver Paste (High-Temperature Sintered Silver Paste) Industry Market In-depth Research and Development Prospects Forecast Report” shows that global demand for high-temperature front-side silver paste will reach 3,217.8 tons in 2022, a year-on-year increase of 26.1%.

The downstream of the high-temperature silver paste industry chain is the application field, with TOPCon batteries, BSF batteries, IBC batteries and PERC batteries as its main demand ends. TOPCon cells are N-type cells, which have the advantages of good high-temperature stability, high conversion efficiency, and small light attenuation. They are expected to become the mainstream product of photovoltaic cells in the future. Attracted by the market prospects, many photovoltaic companies in my country have laid out the TOPCon cell production track, driving the further expansion of their production capacity, which has brought broad development space for the high-temperature silver paste industry.

After years of development, the localization level of my country’s high-temperature silver paste market has continued to improve, and it has become a mainstream product in the photovoltaic silver paste market. The main players in my country’s high-temperature silver paste market include Suzhou Goodtech, Sanfu Xinke, Dike Co., Ltd., Juhe Materials, etc. Among them, Dike Co., Ltd. occupies nearly 15% of the market share and is the leading high-temperature silver paste company in my country.

Industry analysts said that high-temperature silver paste has the advantages of high temperature resistance, good conductivity, and corrosion resistance, and is a representative product of photovoltaic silver paste. . In recent years, with the increasingly strong market demand and the improvement of independent research and development capabilities of local enterprises, the localization process of my country’s high-temperature silver paste market has continued to accelerate. It is expected that in the future, with the further reduction of raw material costs, my country’s high-temperature silver paste production capacity and output will further increase.
