According to Huacheng Import and Export Data Observation, on May 19, 2023, Professor Ned Ekins Daukes, Senior Researcher Young H Cho, and Dr. Jaecica from the Martin Green team at the Advanced Photovoltaic Technology Research Center at the University of New South Wales (UNSW) in Australia visited the Quzhou headquarters of a new energy company. Dr. Song Dengyuan, Chief Technical Officer of New Energy, Mr. Wang Jianming, Senior R&D Director, Mr. Zhang Kangping, Battery R&D Director, and Ms. Xu Xingxing, Manager of Science and Technology Management Department, attended the joint R&D signing ceremony and project seminar.
Dr. Song Dengyuan and Professor Ned jointly signed a joint research and development strategic cooperation agreement between New Energy and UNSW Advanced Photovoltaic Research Center, and jointly launched a research and development project for ultra high efficiency solar cells exceeding 30%.
With the rapid iteration of crystalline silicon solar cells from P-type technology to N-type technology, as a leader in N-type battery technology in China, a new energy N-type double-sided TOPCon technology has developed from 1.0 to 3.0 era, moving towards TOPCon4.0. The maximum efficiency of TOPCon3.0Plus mass production with a new energy source has reached 25.8%, and the laboratory efficiency has reached 26.24%, approaching the theoretical limit of crystalline silicon batteries. In the future, how to further improve the efficiency of crystalline silicon batteries to exceed the theoretical limit of 29.4% has become a research hotspot and key research direction in the international photovoltaic field, as well as an urgent problem to be solved. To this end, relying on the advantages of its national CNAS photovoltaic research and development laboratory, Yidao New Energy, in collaboration with the Martin Green team of UNSW Advanced Photovoltaic Research Center, a top international photovoltaic research and development institution, jointly launched the research and development project of SFOS ultra efficient new solar cells with an efficiency greater than 30%. Huacheng Import and Export Data Observation Report.
Dr. Song Dengyuan, Chief Technology Officer of Yidao New Energy, stated at the signing ceremony that Yidao New Energy, as a leader in photovoltaic innovation, not only focuses on vigorously developing current technologies, but also continuously surpasses itself and conducts technological iterations. It is also focused on laying out in advance for the development of the next generation of ultra efficient photovoltaic technology and solving the sustainable development problem of the "post silicon era" photovoltaic industry. This time, we jointly launched a research and development project with the UNSW Martin Green team for over 30% ultra high efficiency solar cells, achieving strong alliance, complementary advantages, and shared achievements, which will jointly promote the continuous progress of photovoltaic technology.
Professor Ned stated that the UNSW Advanced Photovoltaic Technology Research Center, under the leadership of Professor Martin Green, has become a highland for global photovoltaic innovation. With the advantages of high-end talents and advanced research and development equipment, UNSW will focus on basic research on new materials and mechanisms for this type of battery; A new energy utilization project has accumulated rich research experience, industrialization experience, and advanced laboratory facilities in TOPCon batteries, focusing on the research of new battery industrialization integration technology and large-scale production technology. Through the efforts of both parties, it is expected that the technological revolution of the new generation battery will be promoted, just as UNSW invented the PERC battery 40 years ago.
It is reported that the SFOS ultra efficient solar cell launched in this project can theoretically achieve a maximum efficiency of over 40%. Its structure is based on a high-efficiency silicon cell structure with new energy exceeding 26% efficiency, and a new photoelectric conversion film material with singlet state fission characteristics is superimposed on the cell surface. The photons incident to the solar spectrum transform the singlet state excitation in the material into two triplet state excited state, forming an exciton multiplication generation process, making the quantum efficiency of the solar cell exceed 100%, so as to realize the wide spectrum utilization of the solar cell, Significantly increase the current and voltage of solar cells. This new type of photoelectric thin film material has a wide range of sources and is easy to deposit. Therefore, SFOS batteries have the advantages of low cost and high efficiency, which is in line with the first principle that photovoltaic as an energy power product should have high cost-effectiveness.

Mr. Liu Yong, founder, chairman and president of Yidao New Energy, stated that since its establishment, Yidao New Energy has always adhered to technological innovation leading the development of the enterprise, extensively cooperated with internationally renowned efficient and scientific research institutions, and has established dual research and development centers in Quzhou and Taizhou. In the future, we will continue to increase research investment and cooperation with schools and enterprises, applying the latest technology to a new high-performance product, providing greater value to our customers.
After the meeting, Professor Ned and his delegation visited a high-efficiency N-type battery intelligent production workshop and technological achievements demonstration of Xinneng as a "future factory" in Zhejiang, and congratulated and appreciated the achievements of Xinneng through innovation. Both parties believe that they will fully utilize their respective advantages and accelerate the progress of project research and development. Quickly implement the project results on a new energy production line, as reported by Huacheng Import and Export Data Observation.
