Recently, the China Association for Science and Technology (CAST) released the selection results of the 2023 “Science and Technology for China” series of lists. A total of 230 projects were selected for inclusion in the list, including 150 projects in the list of pioneering technologies and 50 projects in the list of emerging enterprises, after preliminary and final evaluation. Among them, Anhui Guangzhi was successfully selected for the list with its “ultra-thick, large-size and high uniformity CVD ZnSe large-scale production technology”! This is also the only project on the list in Anhui Province, marking an important breakthrough in scientific and technological innovation and product development, and highly recognized by the China Association for Science and Technology.

In order to focus on core technology research in emerging frontier fields and industrial foundation fields, cultivate and expand the team of science and technology-based small and medium-sized enterprises (SMEs), and give full play to the important catalytic role of technology managers in the transformation of scientific and technological fruits, the China Association for Science and Technology (CAST) has launched the brand of “Science and Technology for China” in 2020. It aims to promote the deep integration of science and technology with the economy, set up a wind vane for the deep integration of industry, academia and research, and strive to open up the key links from strong science and technology to strong industry and strong economy. Anhui Guangzhi was selected for the Pilot Technology List, which is oriented to the industrial needs of six major fields, namely, electronic information, biomedicine, equipment manufacturing, advanced materials, green low-carbon, and industrial foundation, and selects the pilot technology achievements that represent the cutting-edge level of the field, and have groundbreaking breakthroughs and broad application scenarios, and can be transferred, transformed, and traded.

ZnSe Materials

Ultra-thick, large-size and high uniformity CVD zinc selenide is one of the “star products” developed by the company. Zinc selenide is an inorganic compound material with low absorption of infrared wavelengths and transmittance of visible light, which is the preferred material for making infrared lenses, windows, output coupling windows and beam expanding mirrors, and is an important material for making high-power carbon dioxide lasers. For a long time, zinc selenide preparation technology and large-size zinc selenide products are subject to overseas embargo, which seriously affects the development of the industry. At the same time, the complete set of large-size zinc selenide preparation technology belongs to the domestic blank. Its deposition system design is complex, the synthesis process is difficult to develop, high-precision processing is difficult, and large-scale production faces great challenges. In this regard, Anhui Guangzhi based on the major needs of the national strategic materials, after years of unremitting research and development, the first digital integration of automated control of large-scale chemical vapor deposition system, the development of a uniform temperature field distribution and in-situ high-temperature annealing process combined with the new process system. At present, the company can produce ultra-thick and large-size high uniformity CVD zinc selenide, the product performance has reached the international advanced level.

New honor inspires new development, new power to achieve new heights. In the future, VOT Intelligence will take this selection of the list of the Association for Science and Technology as an opportunity to continue to create a new situation for scientific research, accelerate the cultivation of the company's new quality productivity, and provide hardcore power for the realization of high-quality development of China's photovoltaic industry.
