The photovoltaic R&D team shuttles repeatedly between the laboratory and outdoors to capture the best sunlight. The progress of spacecraft material testing has been repeatedly hindered due to the difficulty in simulating space lighting. To improve the quality of crops, agricultural growers can only passively rely on the weather - these predicaments caused by "uncontrollable light" have long been a major problem for the development of many industries. For two decades, Beijing Saifan Optoelectronics has been deeply engaged in the field of optical technology. The solar simulator it has developed replicates the natural spectrum with military-grade precision, making "customized sunlight on demand" a reality and injecting new impetus of innovation into the photovoltaic, aerospace, scientific research, agriculture and other fields.
I. Hardcore Technology: This "Artificial Sunlight" is precise to the "minute"
The solar simulator of Saifan Optoelectronics, with its three core technological advantages, has become a representative of "precise light" in the industry.
Spectral Replication: A "Full-Dimensional Restoration" from the Earth's Surface to the Universe
It adopts the golden combination architecture of "xenon lamp main light source + LED supplementary light", and is equipped with the self-developed 5th generation spectral fitting algorithm (trained and optimized with 100,000 sets of natural light data), achieving full coverage of the 400nm to 1100nm wavelength band, and the spectral matching degree reaches the A + level. Whether it is simulating the intense midday light on the surface under the AM1.5G standard, or the space without atmospheric light in the AM0 mode, or even the weak light on the surface of Mars and the extreme temperature difference light environment on the moon, the consistency deviation of each band is ≤1%, completely solving the industry pain point of "disconnection between laboratory data and actual scenarios", making every test accurate and reliable.
Stable output: Millisecond-level regulation, "zero data fluctuation"
It is equipped with a 0.1ms-level high-precision silicon photonics sensor and an FPGA high-speed processing chip, building a closed-loop system of "real-time monitoring - dynamic adjustment - precise feedback", with the light intensity fluctuation strictly controlled within ±0.3% per hour. Even if the test is conducted continuously for 8 hours without interruption, the light intensity deviation is only equivalent to the heat generated by a burning match. This provides a "zero-interference" testing environment for scenarios that require stable lighting, such as the durability test of photovoltaic modules and the long-term aging experiment of spacecraft materials, eliminating experimental errors caused by light fluctuations.
Long-lasting energy saving: Maintenance-free for ten years, costs "cut to the bottom"
High-quality LED light sources with a lifespan of up to 100,000 hours are selected. Calculated based on an 8-hour daily operation, they can be used continuously for 34 years, which is five times longer than the lifespan of traditional xenon lamp equipment, significantly reducing the cost of light source replacement and equipment downtime. Meanwhile, the overall power consumption of the machine is only 650W, which is over 70% more energy-efficient than similar products. Take a 24-hour photovoltaic production line as an example. The electricity cost saved by one Saifan simulator in a year can cover nearly 50% of the equipment procurement cost, achieving a win-win situation of "efficient use + low-cost operation and maintenance".
Ii. Scene Empowerment: "A Beam of Light" Activates Innovation Potential in Multiple Fields
The solar simulator of Saifan Optoelectronics is not only an experimental tool but also an "innovation engine" that drives various industries to break through bottlenecks, creating significant value in different scenarios.
Photovoltaic Field: The "Double Enhancement Code" for Efficiency and Quality
A leading photovoltaic enterprise, in the research and development of perovskite solar cells, once had its efficiency stuck at 24% for a long time due to insufficient absorption in the near-infrared band. After introducing the Saifan solar simulator, the R&D team, with the help of the full-band control function of the equipment, precisely targeted the optimization space in the 780-1100nm band. By adjusting the spectral ratio, they eventually increased the battery conversion efficiency to 27.5%. The related achievements were successfully published in the international authoritative journal "ACS Energy Letters". In the mass production stage, an automated test line composed of 12 Saifan simulators operates efficiently at A speed of 60 cells per minute. With a test accuracy of ±0.3%, the A-grade product rate of polycrystalline silicon cells has soared from 87% to 95%, reducing costs for the enterprise by over 20 million yuan annually and accelerating the iteration and upgrading of photovoltaic products.
Aerospace field: The "Light Shield Guardian" for Spacecraft safety
During the research and development of solar cell wings for the space station, the China Academy of Space Technology needs to simulate the complex lighting environment in space to test the durability of materials. The AM0 space spectrum reproduced by the Saifan simulator perfectly recreates the cosmic light conditions without atmospheric filtration. Through 720-hour low-temperature irradiation tests, it accurately captures the aging patterns of materials, helping the R&D team screen out new protective materials and extending the lifespan of the battery wing coating by three times. In the Mars exploration mission, the Saifan special team completed the development of a customized light source module in just 7 days, increasing the irradiance in the 800-1100nm band by 30% and improving the power generation efficiency of the optimized Mars rover's solar panels by 22%, thus building a solid "safety line" for the energy supply of the exploration mission.
Scientific Research and Agriculture: The "Photodynamic Source" of Cross-border Innovation
Relying on the spectral control capability of the Saifan simulator, the research team from Qingdao University of Science and Technology optimized the crystal orientation of tin-lead alloy perovskite films, increasing the photocatalytic hydrogen production efficiency by 40%. This has contributed to the publication of over 20 research achievements in SCI journals and promoted scientific research breakthroughs in the field of new energy. A certain flower base in Yunnan Province has increased the anthocyanin content of blue roses by 22% through a customized "35% blue light + 5% ultraviolet" lighting scheme by Saifan Simulator, extended the flowering period by 7 days, and achieved a market premium of 30%, significantly enhancing the economic value of agricultural products. The strawberry plantations in Shandong have adopted a customized spectrum dominated by red light, which has increased the sweetness of strawberries from 12 degrees to 14 degrees, raising the yield per mu by 150 kilograms. The 20-mu base has seen an annual income increase of over 160,000 yuan, providing a new path for high-quality agricultural development.
Iii. Service Assurance: Not Just Equipment, but a "Long-term Partner"
Saifan Optoelectronics is well aware that high-quality products require comprehensive service support. We have established 7 major regional spare parts centers across the country, reserving over 95% of commonly used spare parts. We promise a "7× 24-hour response + 48-hour on-site service". When a sudden equipment failure occurred on a certain automotive inspection line, Saifan engineers arrived at the scene within 2 hours and completed the repair within 4 hours, avoiding a daily production halt loss of 500,000 yuan for the enterprise. Solve users' worries with efficient responses. In addition, Saifan regularly holds technical training courses and has cultivated over 300 professional operation talents. The test fixtures customized for aerospace customers have been granted national patents, and laboratories have been jointly established with multiple research institutions to continuously promote technological iteration and upgrading. Today, Saifan solar simulators have served over 200 customers worldwide, with a core repurchase rate of 82%. 85% of new customers come from word-of-mouth recommendations from existing customers, winning market recognition with its strength.
