Photovoltaic enterprises have repeatedly postponed tests in wait for ideal sunlight. Research teams have experienced data gaps in experiments due to seasonal light changes. Agricultural growers have been troubled by the uneven natural light affecting crop quality. For a long time, "uncontrollable sunlight" has always been a key bottleneck restricting the development of multiple industries. Now, with 20 years of in-depth research in optical technology, Beijing Saifan Optoelectronics has developed a solar simulator that can precisely replicate the natural spectrum, completely breaking the constraints of natural conditions and bringing a brand-new possibility of "using light as needed" to fields such as photovoltaics, aerospace, scientific research, and agriculture.
First, precise replication: This "artificial sunlight" is more reliable than nature
In the technological world of Saifan Optoelectronics, "sunlight" is no longer a random variable but an experimental partner that can be precisely regulated.
Spectral Matching: "Full-scene Coverage" from the Earth's surface to space
Adopting A "xenon lamp + LED" hybrid light source architecture and in combination with the independently developed 5th generation spectral fitting algorithm, the Saifan solar simulator achieves full-band coverage from 400nm to 1100nm, with a spectral matching degree reaching the A + standard. Whether it is simulating the intense midday light on the surface of AM1.5G, or the space without atmospheric light of AM0, or even the special spectral environment of extreme celestial bodies such as Mars and the Moon, it can achieve a consistency deviation of ≤1% in each band, making laboratory data perfectly match real application scenarios and completely solving the industry problem of "disconnection between experimental data and reality".
Stable output: Millisecond-level regulation, zero data fluctuation
Equipped with a 0.1ms-level high-precision silicon photonics sensor and an FPGA high-speed processing chip, a closed-loop system for real-time monitoring and dynamic regulation is constructed, with the light intensity fluctuation strictly controlled within ±0.3% per hour. Even if it operates continuously for 8 hours, the light intensity deviation is less than the heat of a match, providing a stable and reliable lighting environment for photovoltaic module inspection and spacecraft material aging experiments that require long-term continuous testing, and eliminating experimental errors caused by light fluctuations.
Long-lasting energy saving: No need to replace the light source for ten years, with costs reduced by 70% directly
The LED light source with a lifespan of up to 100,000 hours is selected. Calculated based on an 8-hour daily operation, it 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 downtime. Meanwhile, the overall power consumption of the machine is only 650W, which is over 70% more energy-efficient than similar products. For a photovoltaic production line that operates 24 hours a day, the electricity cost saved in a year can cover nearly half of the equipment investment, achieving the dual value of "efficient use + low-cost operation and maintenance".
Second, Cross-domain empowerment: "A Beam of Light" Rewrites the development patterns of multiple industries
The solar simulator of Saifan Optoelectronics is not only an experimental device but also a core engine driving industry innovation, creating significant value in multiple fields.
Photovoltaic field: An "Accelerator" for Efficiency Breakthroughs and Quality Upgrades
In the research and development of perovskite solar cells, a leading photovoltaic enterprise once had its efficiency stuck at 24% 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 regulation function of the equipment, precisely located the optimization space in the 780-1100nm band. Eventually, the battery conversion efficiency was increased to 27.5%, and the related results were successfully published in 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. The ±0.3% test accuracy has increased the A-grade product rate of polycrystalline silicon cells from 87% to 95%, saving the enterprise over 20 million yuan in costs annually.
Aerospace field: The "Light Shield Guardian" for the Safe exploration of spacecraft
In the research and development of solar cell wings for the space station, the China Academy of Space Technology used the AM0 space spectrum reproduced by the Saifan simulator to conduct 720-hour low-temperature irradiation tests, accurately capturing the aging patterns of materials. The new protective materials selected have extended the service life of the cell 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%, providing stable energy support for 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 orientation of tin-lead alloy perovskite films, increasing the photocatalytic hydrogen production efficiency by 40% and contributing to the publication of over 20 research achievements in SCI journals. The Yunnan flower base has adopted a lighting scheme with a 35% blue light ratio and ultraviolet assistance, which has increased the anthocyanin content of blue roses by 22%, extended the flowering period by 7 days, and achieved a market premium of 30%. The strawberry plantations in Shandong have adopted a customized spectrum dominated by red light, which has increased the sweetness of strawberries by 2 degrees, raised the yield per mu by 150 kilograms, and increased the annual income of the 20-mu base by over 160,000 yuan.
Three, full-cycle service, not just equipment, but long-term partners
Saifan Optoelectronics is well aware that high-quality equipment requires comprehensive service support. The seven major regional spare parts centers across the country stock over 95% of commonly used parts and promise "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. In addition, the regularly held technical training courses have cultivated over 300 professional talents. The test fixtures customized for aerospace customers have obtained national patents. Moreover, 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.
