Amid the global energy transition wave, solar simulation technology, as a core support for photovoltaic research and development, photocatalysis research and aerospace engineering, is becoming a key force driving industrial upgrading. Beijing Saifan Optoelectronic Technology Co., LTD. (hereinafter referred to as "Saifan Optoelectronic"), with 20 years of technological accumulation, takes the 3A-level steady-state LED solar simulator as its core product and has built a full-chain solution covering R&D, testing and certification, helping scientific research and industry break through technological boundaries.
1. 3A-level technical standard, redefining the accuracy of sunlight simulation
The 7IS0503A-LED 3A-level steady-state LED solar simulator independently developed by Saifan Optoelectronics sets a new benchmark with industry-leading technical indicators:
Spectral matching breaks through the limit: Covering the entire band from 400 to 1100nm, the spectral matching degree reaches A + level (0.875-1.125), and can accurately reproduce multiple standard solar spectra such as AM0 (space environment) and AM1.5G (ground standard), solving the spectral drift problem of traditional xenon lamp simulators.
Dual excellence in stability and uniformity: Both spatial non-uniformity and temporal stability reach Grade A (better than ±2%), with a spot size of Φ70mm, ensuring that the repeatability error of test data is less than 1%, meeting the testing requirements of aerospace-grade components.
Innovation in long lifespan and low power consumption: The lifespan of LED light sources can reach up to 100,000 hours (approximately 11 years), which is more than five times that of traditional xenon lamps. The overall power consumption of the machine is only 650W, which saves 70% energy compared with xenon lamp equipment and significantly reduces the usage cost.
Second, multi-dimensional application scenarios empower innovation throughout the entire industrial chain
1. Photovoltaic field: Precise support from laboratory to mass production
In the research and development of perovskite/silicon tandem cells, a leading enterprise used the Saifan simulator for electrical performance testing and successfully increased the conversion efficiency to 25.8%, which was 2 percentage points higher than the original technology. The simulator supports synchronous testing of quantum efficiency (QE/IPCE), helping enterprises optimize the defect density of thin films and achieve storage stability in a nitrogen environment for 6,000 hours. The related results were published in "ACS Energy Letters".
In the mass production stage, Saifan provided multiple 7IS0503A-LED simulators for a certain enterprise, established a standardized test production line, increased the mass production efficiency of polycrystalline silicon cells by 1.5%, and increased the annual production capacity by 200MW. The comprehensive laboratory for standard testing of solar cells and photovoltaic materials at its R&D headquarters has been certified by the National Institute of Metrology of China and has provided testing services such as spectral response and I-V characteristics for more than 50 customers cumulatively.
2. Aerospace field: Facilitating space verification for the vast universe
The Beijing Institute of Aerospace Metrology and Testing Technology used the Saifan 3A-level simulator to simulate the AM0 spectrum and verify the stability of the spacecraft's flexible solar cells under extreme temperature and irradiation conditions. Test data provide crucial support for the power system design of manned spaceflight projects, ensuring the long-term reliability of batteries in the space environment.
3. Research Frontiers: An innovative Engine of multi-disciplinary integration
In the research on photocatalytic water splitting for hydrogen production, the team led by Professor Zhou from Qingdao University of Science and Technology optimized the orientation of tin-lead alloy perovskite films through the regulation of the ultraviolet-visible spectrum of the Saifan simulator, enabling the battery conversion efficiency to exceed 22.6%. The equipment supports simultaneous testing of photoluminescence (PL) and quantum efficiency, providing multi-dimensional data for material mechanism research.
In the field of agriculture, the Saifan simulator helps research institutions reveal the mechanism by which light quality affects plant photosynthesis by simulating the light cycles of different seasons. The related achievements have been applied to the design of intelligent greenhouse light control systems.
Iii. Exhibitions and Industry Recognition: A Testament to Strength in the Global Market
At the 2025 Munich Shanghai Optoelectronic Expo and the Changchun International Optoelectronic Expo, the Saifan 3A-level simulator became the focus, attracting well-known European testing institutions to purchase multiple devices for third-party certification. The cooperation intentions reached during the exhibition have further consolidated its leading position in the global field of optoelectronic testing equipment.
Industry authoritative reports show that Saifan Optoelectronics holds an important share in the 3A-level steady-state LED solar simulator market, competing on the same stage with international brands such as Newport and Abet. Its technological innovation achievements have won the gold award of the Beijing Innovation and Invention Competition for many times and have been included in the government procurement list.
Fourth, a full-cycle service system to create a worry-free cooperation experience
Saifan Optoelectronics builds a three-dimensional service network:
Technical support: Our professional team offers customized solutions, such as developing a wide-temperature-range test fixture for a certain aerospace client, which has been certified with a national patent.
Training and Certification: Regularly hold "Solar Simulation Technology Training Courses", and have cultivated over 300 professional and technical talents.
Quick response: 7× 24-hour after-sales hotline and spare parts warehouse ensure that equipment malfunctions are repaired within 24 hours.
V. Future Outlook: Drive Sustainable Development through Innovation
Facing the market opportunity of global photovoltaic installed capacity exceeding 2TW by 2025, Saifan Optoelectronics is accelerating the layout of ultra-large format simulators and AI spectral control technology. It is planned to launch aerospace-grade products covering a wavelength of 1800nm to meet the testing requirements of satellite solar panel batteries. Meanwhile, intelligent algorithms are developed to achieve dynamic spectral adaptation to different experimental scenarios.
"Let every beam of light precisely serve the progress of mankind." Saifan Optoelectronics has always taken technological innovation as its core driving force and continuously provided "Chinese precision" for the new energy revolution. Whether it is the cutting-edge exploration in the laboratory or the rigorous verification in the space environment, the Saifan LED solar simulator has always been a reliable "artificial sun" for both scientific research and industry.
