10*10 cm CIGS thin film solar cell device On July 27, the Ministry of Science and Technology formally issued a notice and the Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences as the lead unit approved the first national major scientific research project in Shenzhen. The key scientific issues of new copper-based compound thin-film solar cell related materials and devices "pass the inspection. The project's chief scientist Xiao Xudong led the team around the key scientific issues of new materials and devices related to copper-based compound thin-film solar cells, focusing on the research and development of high-efficiency, low-cost thin-film solar cells, and the development of pilot-scale process technologies and core equipment for industrialization. . Through the implementation of the project, a CIGS battery device with a photoelectric conversion efficiency as high as 21.3% has been successfully produced (certified by China's Jian Heng, the authoritative testing organization of the country), ranking third in the world, making China the top international player in the research of inorganic thin film photovoltaic devices. Horizontal ranks. The team innovatively proposed the improved "three-step method" CIGS growth process, realized the energy band engineering design and control that is conducive to current collection, and succeeded in using copper vacancies and alkali metal post-treatment processes to achieve effective blunt defects. It has broken through the voltage bottleneck of high-strength component CIGS, and has reserved China's CIGS industry with high-efficiency device technology with global competitiveness and independent intellectual property rights.
