1. Semiconductor materials industry: The company has been deeply engaged in the semiconductor industry for more than 60 years. Through long-term adherence to independent innovation and independent research and development, the company has accumulated profound technical heritage and formed an old, middle-aged and young engineer team. The company firmly implements the "domestic leading and global catching up strategy". Through the efforts in recent years, the company's 8-12 inch silicon material products have greatly narrowed the gap with the global leading enterprises in terms of product categories, technical level and product quality, and has become a leading enterprise in the domestic semi-conductor material industry. In terms of product market application expansion, the company's products have been widely used in consumer electronics, industrial control, high-voltage power transmission and transformation, rail transit, automobile chips, mobile phones and computer chips. On the other hand, the company continues to strengthen cooperation with domestic and global first-class power semiconductor and digital chip manufacturers, and continuously optimize the width and depth, so as to provide market support for the long-term sustainable development of the company. 2. New energy industry: With China reaching its carbon peak in 2030 and the United States rejoining the Paris Agreement in early 2021, the global new energy industry represented by photovoltaic and wind energy will continue to develop rapidly. The company is committed to contributing to the continuous reduction of lcoe (kilowatt hour cost) and the optimization of BOS cost through technological innovation to realize the comprehensive parity Internet access of photovoltaic industry. In the field of photovoltaic new energy, the company attaches great importance to independent technological innovation, industrial innovation and business transformation. Through the expansion and commercialization of G12 silicon wafer technology and laminated tile module technology with global independent intellectual property rights, the company has laid a sustainable development path for the global photovoltaic manufacturing field. Focusing on the industrial reform objectives of photovoltaic monocrystalline silicon wafer manufacturing process more efficiency, more efficiency and more smart (industry 4.0 customized production line and flexible manufacturing) proposed by the company in 2019, the company makes every effort to promote Tianjin industrial base Industrial 4.0 transformation and upgrading of Inner Mongolia industrial base and Jiangsu industrial base. In terms of photovoltaic cells and modules, the company has always adhered to the concept of respecting intellectual property rights, strengthening upstream and downstream industrial chain cooperation and implementing differentiated competition, and continuously developed a new generation of battery technology and laminated tile module technology to improve the market competitiveness of the company's products and the global adaptability of industrial technology and manufacturing methods.
