On March 11, the acceptance meeting for the “Key Technology Research and Development of Ultra High-Efficiency HIT Solar Cells†under the Important Direction Project of the Chinese Academy of Sciences was held at the Shanghai Institute of Microsystem and Information Technology. Liu Guiju, Deputy Director of the Frontier Science and Education Bureau of the Chinese Academy of Sciences, attended the event and delivered a speech. The meeting was chaired by Zhao Huibin, Deputy Director of the Department of Technology. Representatives from the project expert group included Academician Hao Junhao from the Shanghai Institute of Technical Physics, Zhao Jianlong, Deputy Director of the Shanghai Institute of Microsystems, Gao Xiuli, Director of the Department of Science and Technology, and Liu Lei, head of the project team, along with nearly 30 other members.
Zhao Jianlong welcomed the guests on behalf of the Shanghai Institute of Microsystem and expressed gratitude to the Chinese Academy of Sciences for its continued support in new energy technology development. He emphasized that the success of the new energy initiative is due to forward-looking planning, coordination across levels, government support, and close collaboration between research institutions and enterprises. He also highlighted the hard work of the scientific team, noting that multiple favorable factors have contributed to the smooth progress of the project. Reaching technical milestones is a crucial step toward commercialization, and he hopes the project team will continue to advance toward industrial application.
Liu Zhengxin, the project leader, presented a comprehensive summary of the key technology research and development for ultra-high-efficiency HIT solar cells. Following this, Miao Junhao, head of the expert group, led the expert review session. He praised the innovative cooperation model of the Shanghai Institute of Microsystem and commended the significant technological achievements made in a short time. Based on a thorough evaluation of the technical and financial data, the expert group concluded that the large-area (12.5×12.5 cm²) crystalline silicon cell developed by the project team achieved an efficiency of 20.13%, meeting or exceeding all technical requirements. The use of funds was deemed reasonable and compliant, and the provided documentation was complete. The expert group unanimously approved the project's acceptance.
Liu Guiju summarized the meeting and congratulated the team on their successful review. She noted that over the past three years, the team completed laboratory setup, equipment procurement, and team building. Not only did the project pass the acceptance check, but some performance metrics exceeded expectations, reflecting the team’s dedication. Experts provided valuable feedback from both technological and industrial perspectives, offering important guidance for future research.
The Chinese Academy of Sciences comprises over 100 research institutes, focusing on fundamental, strategic, and forward-looking scientific research. It emphasizes basic science while also supporting applied research aimed at bridging the gap between technology and the market. Through top-level design, it aims to nurture technologies for long-term development, connect with local industries, and meet national needs effectively.
The “Research and Development of Key Technologies for Ultra High-Efficiency HIT Solar Cells†is one of the guiding projects under the academy’s initiative. It has successfully met its technical and pilot testing targets. Liu Guiju pointed out several key lessons learned: first, maintaining a global perspective and engaging with the international community ensures high-quality, efficient research. Second, a collaborative model involving industry, academia, and research is essential for success. Third, integrated R&D of processes, equipment, and materials is critical for breakthroughs in high-efficiency solar cell technology. Finally, a solid business model ensures cost control and resource optimization, making the project not only technologically advanced but also economically viable for market entry.
During the meeting, attendees visited the New Energy Technology Center’s high-efficiency solar cell R&D platform, CIGS process platform, and rooftop power generation system, gaining firsthand insight into the project’s progress and potential.
