In today's era of technology-driven development, the power of light is constantly being explored, and the ability to precisely simulate sunlight has become a key yardstick for measuring the depth of scientific research and the height of industry. For two decades, Saifan Optoelectronics has been deeply engaged in the optoelectronics field. With military-grade technical strength, it has developed solar simulators. With its ultimate control over the spectrum and strict adherence to stability, it has become a "core partner for light testing" in photovoltaic, aerospace, scientific research, agriculture and other fields, igniting the spark of innovation in various industries with controllable light.
Technical core: Forging a performance monument for optical testing
Every technical parameter of Saifan Optoelectronics' solar simulator demonstrates the ultimate pursuit of precision. The flagship product, 7IS0503A-LED 3A-level steady-state solar simulator, adopts a hybrid architecture of "xenon lamp main light source + LED band supplementary light", achieving seamless coverage of the full spectrum from 400nm to 1100nm. Relying on the independently developed 5th generation intelligent spectral fitting algorithm, after training with 100,000 sets of natural spectral data, the spectral matching degree has reached the A + level (0.875-1.125), and the spectral consistency deviation of each test point is ≤1%. Whether it is simulating the surface AM1.5G spectrum or the space AM0 spectrum, All of them can accurately reproduce the energy distribution characteristics of sunlight.
Stability is the cornerstone of reliable scientific research data. The equipment is equipped with A 0.1ms-level high-sensitivity silicon photonic sensor and an FPGA high-speed control chip, building a millisecond-level closed-loop feedback system. This strictly controls the light intensity fluctuation rate within ±0.3% per hour, and the spatial uniformity is better than ±2%, far exceeding the IEC 60904-9 A-level standard. The military-grade 6061-T6 aluminum alloy body adopts a design where the optical chamber and the transmission system are airtight and separated. It can still operate stably in extreme environments ranging from -40 ℃ to 60℃, which is also the core advantage that makes it the designated test equipment for the aerospace system. The lifespan of the LED light source is 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, saving 70% energy compared to traditional equipment and significantly reducing long-term usage costs.
Scene Practice: An innovative photodynamic engine for multiple industries
Photovoltaic industry: From Laboratory Breakthroughs to Mass production and quality Improvement
In the race of photovoltaic technology, Saifan simulators have become the key driver for efficiency breakthroughs. The R&D team of perovskite/silicon tandem cells of a leading photovoltaic enterprise, with the help of the full-band fine regulation function of the equipment, precisely captured the absorption shortcoming in the near-infrared band of 780-1100nm. By specifically optimizing the material composition, the battery conversion efficiency jumped from 24% to 27.5%, and the related results were published in ACS Energy Letters. In the mass production stage, an automated test line composed of 8 Saifan simulators, with A detection speed of 60 cells per minute and a test accuracy of ±0.3%, has increased the A-grade product rate of polycrystalline silicon cells by 5 percentage points and reduced the loss of defective products by over 12 million yuan annually.
The photovoltaic material standard testing laboratory of the R&D headquarters of Saifan Optoelectronics has been certified by the National Institute of Metrology of China. It has provided authoritative testing services such as spectral response and I-V characteristics for over 50 enterprises, helping customers shorten the R&D cycle by an average of 40% and increasing the number of patent applications by an average of 35% annually. It has become an "incubator" for photovoltaic technology innovation.
Aerospace field: Ground safety barrier for space exploration
Spacecraft face extreme light tests in space, and ground simulation tests directly determine the success or failure of the mission. The China Academy of Space Technology conducted a 720-hour low-temperature irradiation test on the flexible solar cell wing of the space station using the AM0 spectrum precisely reproduced by the Saifan simulator. The light intensity fluctuation of the equipment in an environment of -40 ℃ is ≤±1.2%, which has completely recorded the aging data of the material under strong ultraviolet radiation. The new protective material screened out has extended the service life of the spacecraft coating by three times, providing core data support for the manned space program.
In response to the special requirements of the Mars exploration mission, the dedicated technical team of Saifan completed the development of the "AM0 Spectrum + Infrared Enhancement" customized module within 7 days, increasing the irradiance in the 800-1100nm band by 30% and perfectly simulating the light characteristics on the Martian surface. The solar panels of the Mars rover, optimized based on the test data of this equipment, have a 22% increase in power generation efficiency, ensuring a stable energy supply for the exploration mission.
Scientific Research and Agriculture: The Spectral Magician of Cross-border Innovation
In the field of scientific research, Saifan simulators provide precise light environments for cutting-edge exploration. The team led by Professor Zhou from Qingdao University of Science and Technology utilized the ultraviolet-visible spectrum regulation function of the equipment to optimize the orientation of tin-lead alloy perovskite films, thereby increasing the photocatalytic hydrogen production efficiency by 40%. The equipment supports synchronous testing of quantum efficiency (QE/IPCE) and photoluminescence (PL), providing multi-dimensional data for material mechanism research. It has contributed to the publication of over 20 scientific research achievements in SCI journals.
In the agricultural sector, the "spectral formula" technology has brought about a quality revolution. By adjusting the 35% blue light ratio and 380nm ultraviolet auxiliary light, the high-end flower base in Yunnan has cultivated blue roses with anthocyanin content increased by 22%, extended the flowering period by 7 days, and achieved a market premium of 30%. The Shandong Strawberry Cooperative has adopted a red light-dominated spectral scheme, which has increased the sweetness of the fruit 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, making "light fertilization" a reality.
Service ecosystem: A reassuring choice with full-cycle protection
Saifan Optoelectronics has established a service system covering the entire life cycle of equipment, ensuring that customers have no worries. Seven regional spare parts centers across the country have over 95% of commonly used components in stock. The service commitment of "7× 24-hour technical support + 2-hour response + 48-hour on-site service" ensures rapid repair of equipment failures. When a sudden malfunction occurred on the inspection line of a certain auto parts enterprise, engineers arrived at the scene within two hours and resumed operation within four hours, avoiding an average daily loss of 500,000 yuan.
