Supplier

Chengdu CNBM Optoelectronic Materials Co., Ltd. was established on December 16, 2009 with a registered capital of 233.7 million yuan. It is a high-tech enterprise under China National Building Materials Group. Production and sales, as well as the design, installation and operation of BIPV photovoltaic systems, create new economic growth points and help China's new energy and new material industries take off. The company implements the important instructions of General Secretary Xi Jinping to the glass industry, insists on theoretical innovation to drive R&D and production, and strives to build a world-class cadmium telluride power generation glass enterprise. In 2011 , the theoretical method of cadmium telluride compound technology was proposed for the first time in the world In 2012 , the New Jersey Institute of Technology's Cadmium Telluride Materials Research Center was renamed China National Building Materials American Optoelectronic Materials Research Center. In 2015 , the project received a special support of 159 million yuan from the National Development and Reform Commission's "Major Project to Enhance the Core Competitiveness of the National Manufacturing Industry" In 2017 , the world's first large-area (1.92㎡) cadmium telluride power generation glass was rolled off the production line, filling the domestic technical gap In 2018 , the world's first large-area (1.92㎡) cadmium telluride power generation glass production line was put into operation. The production line has independent intellectual property rights of Industry 4.0, and the products are supplied to the market in batches and profitable in the same year In 2021 , the laboratory conversion efficiency of 20.24% and the production line conversion efficiency of 16.18% have been achieved, reaching the domestic first-class and international leading level. Power generation glass technology theory won: 2019 Edison Invention Patent Award, First Prize of China Building Materials Federation Technology Invention Award, New Material Award of the 21st International Industry Fair The title of "China's Good Technology" in 2020 . The products entered the National Development and Reform Commission's "Green Technology Promotion Catalogue (2020 Edition)", the Ministry of Industry and Information Technology's "First Batch of Application Demonstration Guidance Catalogue (2019 Edition)", the Army's "Four New" Achievements Promotion and Application Catalogue, and obtained China's first batch of green building materials certification And many other professional certifications at home and abroad. Cadmium telluride power generation glass has advantageous attributes such as low carbon, environmental protection, energy saving, energy creation, and aesthetics. It is one of the important materials to help China realize the strategy of "carbon peaking and carbon neutrality". It has huge development space in the field of new building materials and BIPV. It is a model of promoting supply-side structural reform with technological innovation. It can be widely used in large-scale solar ground power plants, industrial and commercial buildings, modern factories, industrial groups, skyscrapers, etc. At present, it has been put into use in modern landmark buildings such as Chengdu Shuangliu Airport, Nanjing Jiangning Big Data Center, Shanghai Songjiang Triumph Robot Industrial Park, Pengzhou Aviation Science and Technology Expo Park, Lijiang Cement Plant, and other defense facilities such as the new barracks in the Ali front line and the Golmud Southwest Command Center. .
