FTO glass (fluorine-doped tin oxide glass) has broad application prospects, and the development speed of China's industry is accelerating

There are three main types of TCO glass: AZO glass, FTO glass and ITO glass. FTO glass, the full name of fluorine-doped tin oxide glass, is a kind of conductive glass coated with a fluoride-doped tin oxide film on the surface. FTO glass has the characteristics of high visible light transmittance, low cost of raw materials, acid and alkali corrosion resistance, and low surface resistance, and has broad application prospects in photovoltaic power generation, construction engineering, display panels and other fields.

FTO glass is typically prepared by atmospheric chemical vapor deposition (APCVD). Atmospheric pressure chemical vapor deposition method refers to the diffusion of fluorine- and tin-containing precursor gas to the glass plate, and then through adsorption, chemical decomposition, sintering, film formation and other processes to obtain the finished product, this method has the advantages of easy parameter control, good quality of the finished product, etc., suitable for large-scale production. In the future, with technological progress, the development speed of China's FTO glass industry will be further accelerated.


In recent years, China's enterprises and related scientific research institutions have continuously increased the research and development of FTO glass, and have obtained a number of relevant patents, mainly including "a treatment method and battery for photovoltaic conductive FTO glass", "a processing method for laser marking FTO glass", "film removal method for FTO glass, perovskite cell and its preparation method", etc. In the future, with the deepening of research, the proportion of China's high-quality FTO glass market is expected to increase.


According to the "2025-2030 China FTO Glass (Fluorine Doped Tin Oxide Glass) Industry Market In-depth Research and Development Prospect Forecast Report" released by the Xinsijie Industry Research CenterDisplay, FTO glass has broad application prospects in many fields, mainly including photovoltaic power generation, construction engineering, display panels, etc. In the field of photovoltaic power generation, FTO glass has the advantages of good high temperature stability, high light transmittance, and easy laser etching, and can be used as perovskite electrode glass. In the field of construction engineering, FTO glass has the advantages of low operating cost and good conductivity, and can be used to manufacture Low-E glass; In the field of display panels, it can be used to manufacture LCD backplanes.


The global FTO glass market is mainly concentrated in Japan, and the representative companies include Asahi Glass Co., Ltd. (AGC) of Japan, NSG Group of Japan, etc. In terms of locality, with the improvement of the industry's prosperity, the number of participants in China's FTO glass market continues to grow, mainly including Kibing Group, CSG Group, Jinjing Technology, Yao Pi Glass, etc. Kibing Group focuses on the R&D, manufacturing and sales of glass products, and is a representative enterprise of FTO glass in China. According to the announcement of Kibing Group, the company achieved revenue of 11.6 billion yuan in the first three quarters of 2024, a year-on-year increase of 3.7%.


Industry analysts said that FTO glass, as a high-performance conductive glass, has broad application prospects and the development speed of the industry is accelerating. Benefiting from in-depth research and technological progress, the output and quality of FTO glass in China are expected to increase. At present, a number of enterprises in China have laid out the R&D and production track of FTO glass industry, and their market space will be further expanded in the future.
