From September 23rd to 27th, 2025, the "Innovation Science and Technology Museum" of the 25th China International Industry Fair grandly opened in Hall 6.2H of the National Exhibition and Convention Center (Shanghai). With the theme of "Technological Innovation, Intelligent Manufacturing for the Future", this grand event was jointly organized by the Shanghai Technology Entrepreneurship Center, NATIONAL INNOVATION CENTER par EXCELLENCE and other units under the guidance of the Shanghai Municipal Science and Technology Commission. It focused on displaying breakthrough achievements in cutting-edge fields such as future manufacturing, future information, future materials, future energy, future space and future health, becoming a global focal point for technological innovation.
In this technological feast, YIST is undoubtedly one of the dazzling stars, and its strategic positioning and research results have had a profound impact on the global photovoltaic industry.
PART 01: Atop Mount Everest, Forging a New Benchmark for International Standards
YIST, in collaboration with East China University of Science and Technology, successfully built a first-class standard solar cell natural sunlight calibration experimental platform that meets international standards in the Tibet Everest Nature Reserve (at an altitude of 4,236 meters). This initiative holds significant strategic importance. This region boasts solar irradiation resources in China that are closest to the AM1.5 standard spectrum, providing a unique atmospheric optical environment for high-precision photovoltaic performance calibration.
Through this platform, YIST is committed to establishing the "Everest Standard" in the photovoltaic field with international influence. The establishment of this standard not only achieves accurate traceability and reliability verification of solar cell electrical performance testing, but also provides crucial basic data support for China's photovoltaic technology research and development, equipment manufacturing and industrial application. In today's increasingly fierce global photovoltaic industry competition, the emergence of the "Everest Standard" will enable China to take a leading position in the formulation of photovoltaic technology standards, guiding the global photovoltaic industry towards higher quality and more sustainable development.
PART 02: Innovative Breakthroughs, Ushering in a New Era of Satellite Energy
At this exhibition, the low-cost crystalline silicon flexible solar wing, first exhibited by YIST, has attracted widespread attention from the industry. This innovative product is developed based on low-cost silicon-based solar cell technology and has been reinforced specifically for the LEO orbit environment.
Its unique flexible wing structure achieves significant weight reduction, and combined with modular and small-bundle design, it has excellent adaptability and integration convenience. The high-efficiency ultra-thin silicon-based cells selected for the power generation part have a conversion efficiency of not less than 20% under AM0 and 25℃ conditions. Compared with traditional triple-junction gallium arsenide solar wings, the price per square meter has been reduced by an order of magnitude, with significant advantages such as high efficiency, low cost and high specific power.
The launch of this product will bring revolutionary changes to the satellite industry. It supports modular customization according to user needs, and is particularly suitable for low-cost communication satellite platforms, providing a more economical and efficient energy solution for the development of the satellite industry. Against the backdrop of the vigorous development of global satellite internet construction, YIST's low-cost crystalline silicon flexible solar wing will have broad market prospects and is expected to become a mainstream product in the field of satellite energy.
PART 03: Collaborative Development, Leading the New Trend of Scientific and Technological Innovation in the Yangtze River Delta
YIST's participation in this exhibition not only demonstrated its outstanding achievements in cutting-edge new energy technologies and standardization construction, but also highlighted the strong collaborative effectiveness of the Yangtze River Delta region in jointly building and sharing high-level scientific and technological innovation platforms and promoting the deep integration of innovation chains and industrial chains.
Under the national strategic background of the integrated development of the Yangtze River Delta, YIST gives full play to its technical advantages and resource integration capabilities, and closely cooperates with universities, research institutions and enterprises to form a strong innovative synergy. By participating in national-level exhibitions, YIST has brought the photovoltaic technological innovation achievements of the Yangtze River Delta region to the global stage, enhancing the influence and voice of the Yangtze River Delta region in the global photovoltaic industry.
In the future, YIST will continue to uphold the development concept of innovation-driven development, strengthen cooperation with domestic and foreign research institutions and enterprises, continuously explore new boundaries of photovoltaic technology, and make greater contributions to the energy transition and sustainable development of China and even the world. We have every reason to believe that under the leadership of YIST, the Yangtze River Delta region will become a global highland for photovoltaic technological innovation, driving the global photovoltaic industry towards a more brilliant tomorrow.
