In the current era of vigorous technological development, numerous innovative breakthroughs in various industries have put forward strict requirements for precise lighting simulation. As a key device for simulating sunlight, the performance of a solar simulator directly affects scientific research achievements and industrial development. Beijing Saifan Optoelectronic Instrument Co., LTD., with its profound technical accumulation and continuous spirit of innovation, has developed a series of high-performance solar simulators and has become a trusted "light partner" in many industries.
Profound technical heritage has set an industry benchmark
Since its establishment in 2004, Saifan Optoelectronics has been dedicated to the research and development and manufacturing of optoelectronic products, achieving remarkable results in the technical field. Its self-developed technological strength should not be underestimated. The technical team accounts for over 90%. Continuous investment in research and development has enabled the company to win multiple national patents. Some of its products have even been included in the government's designated procurement list. As the first high-tech enterprise in the industry, Saifan Optoelectronics has established a leading position in the industry with its professionalism and innovation.
Take the 7IS0503A-LED 3A-level steady-state solar simulator of Saifan Optoelectronics as an example, its technical advantages are truly outstanding. In terms of spectral simulation, it precisely covers wavelengths from 400nm to 1100nm, with A spectral matching degree reaching the A + level (0.875-1.125), and the spectral consistency at each point is excellent. It can create a highly realistic simulated solar environment for scientific research and testing, solving the problem of spectral drift in traditional xenon lamp simulators. Provide users with stable and reliable spectral data. Both the spatial non-uniformity and temporal stability reach grade A (better than ±2%), with a light spot size of Φ70mm, ensuring uniform and stable illumination. The reliability and repeatability of the experimental data have been greatly enhanced, meeting the extremely high stability requirements of scenarios such as aerospace-grade component testing. In terms of the lifespan and power consumption of the light source, the LED light source has a lifespan of up to 100,000 hours, which is more than five times that of traditional xenon lamps. The rated power of the entire machine is only 650W, with a significant energy-saving effect, saving 70% energy compared to xenon lamp equipment and greatly reducing the long-term usage cost.
Widely applied in multiple fields, it helps industries take off
The "Efficiency Booster" of the photovoltaic industry
In the photovoltaic field, whether in laboratory research and development or mass production, the solar simulators of Saifan Optoelectronics play a crucial role. During the research and development of perovskite/silicon tandem cells, a leading enterprise successfully increased the conversion efficiency to 25.8% by using the Saifan simulator for electrical performance tests, which is 2 percentage points higher than the original technology. This 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 have been published in the authoritative journal "ACS Energy Letters". Entering the mass production stage, Saifan built a standardized test production line composed of multiple 7IS0503A-LED simulators for a certain enterprise, which increased the mass production efficiency of polycrystalline silicon cells by 1.5% and the annual production capacity by 200MW. The comprehensive laboratory for standard testing of solar cells and photovoltaic materials at the R&D headquarters of Saifan Optoelectronics has been certified by the National Institute of Metrology of China. It has provided testing services such as spectral response and I-V characteristics for over 50 customers, effectively promoting technological innovation and capacity expansion in the photovoltaic industry.
The "Space Rehearsal room" in the aerospace field
Spacecraft face extremely complex lighting environments in space, and ground simulation tests are of vital importance. The Beijing Institute of Aerospace Metrology and Testing Technology used a Saifan 3A-level simulator to simulate the AM0 spectrum and verify the stability of flexible solar cells for spacecraft under extreme temperature and irradiation conditions. The simulator accurately reproduces space light, providing key support for the power system design of the manned space program, ensuring the long-term reliable operation of batteries in the space environment, and helping China's space industry steadily move towards deep space.
The "Innovation Catalyst" at the forefront of scientific research
In the research on hydrogen production through photocatalytic water splitting, the team led by Professor Zhou from Qingdao University of Science and Technology utilized the ultraviolet-visible spectrum regulation function of the Saifan simulator to optimize the orientation of tin-lead alloy perovskite films, which led to a battery conversion efficiency exceeding 22.6%. The equipment supports simultaneous testing of photoluminescence (PL) and quantum efficiency, providing multi-dimensional data for in-depth exploration of material mechanisms and promoting scientific research progress in the field of photocatalysis. In agricultural research, the Saifan simulator simulates the light cycles of different seasons, helping to reveal the mechanism by which light quality affects plant photosynthesis. The related achievements have been applied to the design of intelligent greenhouse light control systems, providing a scientific basis for precise agricultural production.
A high-quality service system ensures worry-free use
Saifan Optoelectronics is well aware of the significance of quality service to its customers and has established a comprehensive service network. The technical support team provides customized solutions for customers, such as developing wide-temperature range test fixtures for a certain aerospace customer and obtaining national patent certification, meeting the customer's special needs. The "Solar Simulation Technology Training Course" is held regularly, which has cultivated over 300 professional and technical talents and enhanced the overall technical level of the industry. The 7× 24-hour after-sales hotline and spare parts warehouse are always on standby to ensure that equipment malfunctions are repaired within 24 hours, reducing the losses caused by equipment failures for customers and allowing them to use the equipment without any worries.
From the efficiency improvement of the photovoltaic industry to the space exploration in the aerospace field, and then to the innovative breakthroughs at the forefront of scientific research, Saifan Optoelectronics' solar simulators, with their leading technology, wide application and high-quality services, have become a powerful booster for the innovative development of various industries. If you are seeking a solar simulator with outstanding performance, stability and reliability, Saifan Optoelectronics is undoubtedly your best choice. Let's join hands and, with the help of the precise and controllable "artificial sunlight" of the solar simulator from Saifan Optoelectronics, forge ahead in the wave of technology and open up more possibilities for innovation.
