From a scientist to an entrepreneur, he overcame many difficulties and led the team to explore the technology and industrialization of cadmium telluride power generation glass with blood and sweat. (

hereinafter referred to as Chengdu China Building Materials) has developed and produced a series of large-area cadmium telluride power generation glass products, which not only have the advantages of low carbon, environmental protection and energy creation, but also have the advantages of low C arbon, environmental protection and energy creation. It also has the characteristics of structure, color, light transmittance and shape customization, and has been widely used in different types of buildings such as airports, industrial and commercial buildings, modern factory buildings and national defense construction, so that the building can be transformed from "energy saving" to "energy creation" and "negative energy", which is an important material to achieve the strategic goal of "double carbon" in China, and to reduce building energy consumption and build a new energy system. Play an important role.

Chengdu CNBM was founded in December 2009 with registered capital. 2. The company is committed to the R & D and industrialization of cadmium telluride power generation glass, the production and sales of high-purity rare metal materials, and the design, installation and operation of BIPV photoelectric systems; Promote the industrial revolution with the material revolution, strive to create new economic growth points, and help China's new energy and new material industries take off.

In 2007, Pan Jingong, who also studied in the United States, founded the Cadmium Telluride Thin Film Solar Energy Research Center of New Jersey University of Technology, served as the executive vice director and led the team to take the lead in the research of cadmium telluride material characteristics. For the first time, he and his team proposed the graphical method of multi-level and multi-doped carrier density of cadmium telluride thin film materials, which solved two key problems of copper-doped back contact and dark current blocking materials. This achievement was included in the textbooks of American universities in 2013, while the technology of glass power generation was regarded by the United States as a key technology "related to the future national energy security of the United States".

In 2011, he refused the millions of annual salary offered by the United States, full of enthusiasm to serve the motherland, with the research and technological achievements of power generation glass, as a high-level talent in Sichuan Province and the leader of the top innovation team in Sichuan Province, he settled in Shuangliu, Chengdu, and began to work hard for the industrial application of power generation glass. He led the team to depict the blue sea of cadmium telluride power generation glass industry with a sincere heart.

In 2015, Pan Jingong and the research team of China Building Materials at home and abroad raised the photoelectric conversion rate of small batteries from 10% in 2013 to 18%. The project was supported by 159 million yuan of special funds from the National Development and Reform Commission for the "Major Project of Revitalizing the Core Competitiveness of National Manufacturing Industry";

In 2016, the world's first cadmium telluride power generation glass production line with a large area of 1.92 square meters was installed and constructed; in August of the following year, the world's first cadmium telluride power generation glass with a large area (1.92 square meters) was produced in Shuangliu, Chengdu, which solved the problems of uniform coating of cadmium telluride and defects on the film surface;

In 2018, the world's first large area with independent intellectual property rights (1.

It is reported that as a green and low-carbon energy building material, cadmium telluride power generation glass has the advantages of weak light power generation and beautiful and changeable appearance, which can make the building become a beautiful and environmentally friendly "micro-power station". At present, the power generation glass of Chengdu China Building Materials has achieved a laboratory conversion efficiency of 20.84% and a production line conversion efficiency of 16.

Gu Zhenan, academician of the Chinese Academy of Engineering, believes that in the field of new materials, the significance of cadmium telluride power generation glass is to change China's flat glass from a building material to a functional material that can generate electricity and filter light. From the perspective of the development of national industry, this has built a material technology foundation for China to upgrade from a big country of building materials to a powerful country of electronic glass and semiconductor materials. Cadmium telluride power generation glass has been widely used in the building materials industry, leading a revolution in building materials. The exterior walls of buildings are no longer just cement, bricks and curtain walls, but recyclable and usable recycled materials will be widely used to help achieve the goal of "double carbon".

Pan Jingong, Large-area cadmium telluride power generation glass not only has high photoelectric conversion efficiency, but also completely fits the external shape of the building. At present, it has been widely used in Shanghai, Sichuan, Hebei and other places, and has achieved fruitful results.

Shanghai Songjiang Robot Industrial Park Building is the first comprehensive integration project of cadmium telluride power generation glass in the city center of China. Implementing the concept of zero energy consumption in buildings, the curtain wall adopts cadmium telluride power generation glass with green energy creation, energy saving and environmental protection, realizing the unification of building body and power supply system, and helping to achieve the goal of "carbon peak, carbon neutralization"; "Sky Mirror-Power Generation Glass Roof" is a BIPV project in Panzhihua Graphite Carbon Industrial Park, which directly replaces roofs and walls as building materials, replaces traditional industrial roof color steel tiles and factory walls, and perfectly presents the aesthetic decorative effect of power generation glass; Compared with the crystalline silicon power station of the same scale, the large ground power station in Zhangbei generates more electricity throughout the year. 8

. Chengdu CNBM also actively participated in the construction of the 24th Winter Olympic Games, using low-carbon cadmium telluride power generation glass. It has successively constructed the "Olympic Corridor"-the large-scale mountain restoration ground power station project in Chicheng County, Zhangjiakou, the "Olympic Demonstration Project"-the renovation project of Dida World Expo Plaza in Zhangjiakou and the green low-carbon road sign project of power generation glass in the Winter Olympic Competition Area.

In 2020, Chengdu CNBM actively responded to the call of strengthening the army by science and technology, and used cadmium telluride power generation glass to help the construction of new thermal insulation barracks in Karakoram frontier areas, providing energy support for barracks in plateau and alpine areas, greatly improving the conditions of the garrison.

In 2022, the cadmium telluride power generation glass of Chengdu China Building Materials provided about 5000 degrees of clean electricity per day for the Chuankai Electric Plant during the power limitation period, which solved the urgent need for electricity in the park.
