Solar power grid (Hangzhou): On December 29, 2018, in Xiasha economic and Technological Development Zone, Hangzhou, a new generation of CdTe thin film photovoltaic module production line with full independent research and development and full independent intellectual property rights was officially put into production here, which indicates that Chinese enterprises have the ability to develop advanced CdTe thin film solar cell industrialization technology on a large scale.The project is invested and built by Shenzhen SEG Advanced Solar Power Co., Ltd. (hereinafter referred to as "SEG ASP"), which adopts the new generation of core industrialization technology independently researched and developed by Advanced Solar Power （Hang Zhou）Co., Ltd. (hereinafter referred to as "ASP") with full independent intellectual property rights.Experts from China Academy of engineering, Shanghai Jiaotong University, Zhejiang University, Sichuan University, North China Electric Power University, Nankai University, Shenzhen University of technology, Shenzhen Institute of advanced technology, Chinese Academy of Sciences, China Academy of Building Sciences, China Academy of architectural design and other scientific research institutes and more than 200 representatives from relevant government departments of Hangzhou City, Zhejiang Province, Photoelectric Construction Committee of China Building Metal Structure Association, Hangzhou solar photovoltaic industry association, Shenzhen Solar Energy Association, Shenzhen Green Construction Association, Zhejiang energy group, China Construction Technology Group, Shenzhen Saige group, Shenzhen Energy Nanjing energy, Longyan energy and other institutions and enterprises attended the launch ceremony.

 According to Xuanzhi Wu, chairman of Longyan energy, the 40mW CdTe thin film photovoltaic module production line put into production was only determined to be built in Hangzhou at the beginning of this year. It took only five months to complete the project approval, plant construction, power and power matching, and the equipment was installed and commissioned in July. In late October, the joint commissioning was successful and the first batch of products were produced.fter the first batch of products came off the production line, after only two months of production line debugging, the maximum power of this production line has exceeded 97 watts. "This new production line is designed and built on the basis of summarizing the 7-year production experience of Longyan's first production line. It has been greatly improved in terms of equipment quality, production capacity, process level, component efficiency and stability, which fully shows that ASP has the ability to achieve sustainable and large-scale development." Wu said. In 2001, Wu xuanzhi, who was over the age of seventy, led a scientific research team in the United States to set a world record of 16.7% in the photoelectric conversion efficiency of CdTe thin film solar cells, and kept the record for 10 years. In 2008, he returned to China to establish ASP. He started research and development from the experimental line and pilot line. In 2011, he built the first fully automatic CdTe module production line with full independent intellectual property rights and large-scale mass production capacity in China, and realized the national production of CdTe thin film photovoltaic module core technology.

Today, the efficiency and productivity of the laboratory batteries and production line components of ASP have reached the international advanced level, and the cost of the components has been reduced to less than 1.8 yuan per watt. The products have successively obtained TUV, UL and Golden Sun certification and have been exported to 38 countries and regions.In 2017, ASP and state-owned enterprises SEG and Shenneng Nanjing Energy Holding Co., Ltd. jointly invested to establish Sege Longyan, which is committed to the R&D and manufacturing of CdTe thin film photovoltaic modules. After independent technological innovation, it has taken a key step in resource integration development.

Bao Wang, Secretary of the Party committee and chairman of SEG group, said at the launch ceremony,"CdTe thin film solar cell module is a rising star in photovoltaic products, which has a huge development space in the field of new green building materials, and will also be widely used in agricultural photovoltaic, distributed power generation and many other green environmental protection fields. As a strategic emerging industry development platform positioned by the state owned assets supervision and Administration Commission of Shenzhen, the completion and operation of SEG's CdTe thin film solar module production line has opened a new chapter of SEG group's strategic emerging industry layout, marking that Saige group has officially entered the manufacturing field of high-end solar green clean energy and new green building materials.
