Photovoltaic enterprises repeatedly move equipment under the scorching sun to test the efficiency of their components. The aerospace team spent months building a temporary test module to simulate space lighting. Agricultural researchers have been waiting for the change of seasons to verify the impact of the spectrum on crops. These inefficiencies and helplessness caused by "uncontrollable light" were once common problems in fields such as photovoltaics, aerospace, and agriculture. For two decades, Beijing Saifan Optoelectronics has been deeply engaged in optical technology. The solar simulator it has developed with military-grade technology has brought "ideal sunlight" into the laboratory, making "light as needed" the norm and injecting core impetus into breaking through development bottlenecks in various industries.
I. Technological Breakthrough: This "artificial sunlight" understands demands better than nature
The core advantage of Saifan Optoelectronics' solar simulator lies in achieving the ultimate in "precision, stability and customization of light", completely solving the pain point of traditional experiments that rely on natural light
Spectral Replication: "Full-Scene Restoration from the Earth's Surface to Space"
Adopting an innovative architecture of "xenon lamp main light source + multi-band LED supplementary lighting", combined with the 5th generation spectral fitting algorithm trained on 100,000 sets of natural light data, it achieves full band coverage from 400nm to 1100nm, and the spectral matching degree reaches the A + level. Whether it is the simulation of the midday strong light under the AM1.5G standard (suitable for photovoltaic module testing), or the AM0 mode of space without atmospheric light (suitable for spacecraft material experiments), or even the weak light on the surface of Mars and the extreme temperature difference spectrum of the moon, the consistency deviation of each band is ≤1%, making the laboratory data align with the real application scenarios with "zero error".
Stable output: Millisecond-level regulation, "zero fluctuation" of experimental data
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 means that projects that require long-term stable light, such as the durability test of photovoltaic modules and the aging experiment of spacecraft materials, will no longer suffer from data distortion due to light fluctuations.
Long-lasting energy saving: No need to replace the light source for ten years, reducing costs and saving you peace of mind
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. For a photovoltaic production line that operates 24 hours a day, the electricity cost saved by a single Saifan simulator in a year can cover nearly 50% of the equipment procurement cost, achieving the dual benefits of "efficient experiments + low-cost operation and maintenance".
Ii. Industry Empowerment: A Beam of Light, Rewriting the Innovation Rhythm in Multiple Fields
The solar simulator of Saifan Optoelectronics is not only an experimental device but also an "innovation engine" that drives various industries to break through technical bottlenecks, creating significant value in practical applications
Photovoltaic field: An "Accelerator" for Efficiency Breakthroughs and Quality Upgrades
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, leveraging the full-band control function of the equipment, precisely targeted the optimization space in the 780-1100nm band. By adjusting the spectral ratio, they increased the battery conversion efficiency to 27.5% in just three months. The relevant achievements have been 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 Guardians" of Space exploration
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. Brand Strength: Twenty years of in-depth cultivation have established a benchmark in the field of optical testing
The confidence of Saifan Optoelectronics stems from two decades of technological accumulation and a deep understanding of user needs: As a high-tech enterprise in the field of optical technology, Saifan has a research and development team composed of over 90% professional technicians. Its independently developed core technologies such as spectral fitting algorithms and high-precision sensors have obtained multiple national patents. We have set up 7 major regional spare parts centers across the country, reserving over 95% of commonly used components. 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. In addition, Saifan regularly holds technical training courses, has cultivated over 300 professional operation talents, and has jointly established laboratories with many 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.
