The "Ultra High Efficiency HIT Solar Cell Key Technology Research and Development" project passed

On March 11th, the acceptance of the “Key Technology Research and Development of Ultra High-Efficiency HIT Solar Cells” of the Important Direction Project of the Chinese Academy of Sciences was held at the Shanghai Institute of Microsystem and Information Technology of the Chinese Academy of Sciences. Liu Guiju, Deputy Director of the Frontier Science and Education Bureau of the Chinese Academy of Sciences attended the conference. He also spoke at the meeting and was chaired by Zhao Huibin, Deputy Director of the Department of Technology. The head of the project expert group, academician Hao Junhao of the Shanghai Institute of Technical Physics of the Chinese Academy of Sciences, Zhao Jianlong, deputy director of the Shanghai Institute of Microsystems of the Chinese Academy of Sciences, Gao Xiuli, director of the Science and Technology Department, and 30 members of the project team attended the meeting.

First of all, Zhao Jianlong welcomed the arrival of the leaders and experts of the Chinese Academy of Sciences on behalf of the Shanghai Microsystems Institute and thanked the Chinese Academy of Sciences for its interest in the development of new energy technologies. He said that the establishment of a new direction for new energy technologies is inseparable from the hospital's forward-looking layout, coordination and coordination at all levels, support from local governments, and close coordination between companies and the enterprise, and it is also inseparable from the hard work of the scientific research team. Multiple favorable factors are intertwined to jointly promote the smooth progress of the New Energy Technology Center project. Completion of technical indicators is an important step towards the market. It is hoped that the project team will be able to pass inspections by experts and go further on the path of follow-up industrialization.

Then, Liu Zhengxin, the project leader, made a summary report on “Key Technology Research and Development for Ultra High-Efficiency HIT Solar Cells”.

Later, as the head of the expert group, Junjun Hao presided over the expert inquiries and questions of the project acceptance meeting. He believes that Shanghai Microsystems has innovation in its cooperation model and has made remarkable achievements in technology within a short period of time. It is worth learning from other research units. . Based on the review and full discussion of acceptance technology and financial information, the expert group formed an acceptance opinion: After a third party inspection, the efficiency of the large-area (12.5*12.5cm2) crystalline silicon cell developed by the project team reached 20.13%, and other technical parameters All can meet or exceed the requirements of the indicators, the use of funds is reasonable, in line with relevant regulations, and the acceptance information provided is complete. The expert group unanimously agreed that the project passed acceptance.

Finally, Liu Guiju made a summary of the project acceptance. She congratulated the team on the successful review. She believes that the team completed the laboratory preparation, equipment introduction, and team building in more than three years. Not only did the project pass the acceptance check, but some of the indicators exceeded the task, indicating that the team made a lot of effort. . Experts commented on this project from two different perspectives: technology and industry, and made recommendations, which are instructive for the research of the project team.

There are more than 100 research institutes in the Chinese Academy of Sciences and they are positioned as basic, strategic and forward-looking scientific research. On the one hand, it attaches importance to basic research, aims to climb the peak of science and technology, faces the international frontier, and at the same time draws out some fund-support oriented research. It aims to establish a close relationship between technology and the market and hopes to pass some technology through the top-level design for a period of time. Cultivate, go to the market, connect to the "local gas" and truly meet the needs of the country.

"The research and development of key technologies for ultra-high-efficiency HIT solar cells" is one of the guiding researches and has reached the expected technical and pilot test targets. The project was able to pass the inspection and acceptance. Liu Guiju believes that there are several points worthy of summing up: 1. A broad international perspective is the premise, maintaining good communication with the international community, a high starting point, guaranteeing advanced research, and reducing repetitive labor and waste of resources; 2 The joint mechanism of good production, learning, research, and use is a guarantee. This team cooperates with well-known companies in the industry. The two sides invest funds, manpower, financial resources, and equipment, and use a joint laboratory as a carrier to integrate into one and achieve the same goals. The smooth development of the project; 3. The collaborative R&D of process, equipment, and materials is the key. High-efficiency HIT battery technology is a comprehensive technology. Equipment and materials are highly dependent on each other, and the single technology advances synergistically before it can finally break the efficiency bottleneck. 4. Business model It is very important, whether it is the research process or the transfer and transformation process, the establishment of a good business model, the cost accounting through the R&D and pilot testing process, the effective use of all available resources, and the guarantee that the project is not only technologically advanced but also has cost advantages, and is ready for the project to reach the market. . It is hoped that the project team will not be satisfied with passing the acceptance test, sticking to the follow-up pilot study, trying hard to accept the test of the market, and finally being recognized by the cooperative enterprise and the market.

During the meeting, leaders and experts visited the New Energy Technology Center's high-efficiency solar cell R&D platform, CIGS process platform, and rooftop power generation system.
