In the field of light testing technology, accurately simulating the sunlight environment is the key to promoting scientific research breakthroughs and industrial upgrading. For two decades, Saifan Optoelectronics has been deeply engaged in the optoelectronic field. The solar simulator it has developed, with its military-grade performance indicators, all-scenario adaptability and profound technical accumulation, has become the "core light testing equipment" in the photovoltaic, aerospace, agriculture, scientific research and other fields, illuminating the innovation path of various industries with controllable light.
Technical core: Reaching a new height in optical testing performance
The core advantage of Saifan Optoelectronics' solar simulator lies in the meticulous refinement of every technical indicator. Its flagship product, the 7IS0503A-LED 3A-level steady-state solar simulator, adopts a hybrid architecture of "xenon lamp main light source + LED band supplementary light", achieving full-spectrum coverage from 400nm to 1100nm. The independently developed 5th generation intelligent spectral fitting algorithm, trained with 100,000 sets of natural spectral data, has achieved A spectral matching degree of A + level (0.875-1.125), with a spectral consistency deviation of no more than 1% at each test point, perfectly reproducing international standard spectra such as AM0 (space) and AM1.5G (surface).
In terms of stability, 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 reason why it has become 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 Implementation: The "Optical Power Source" for Innovation in Multiple Industries
Photovoltaic industry: Full-chain empowerment from laboratory to production line
In the photovoltaic technology race, the Saifan simulator has become the key to efficiency breakthroughs. The R&D team of perovskite/silicon tandem cells of a leading photovoltaic enterprise, with the help of the full-band segmentation regulation function of the equipment, accurately captured the absorption shortcoming in the near-infrared band of 780-1100nm. After optimization, the cell conversion efficiency jumped from 24% to 27.5%. 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.
Aerospace field: The "Ground Rehearsal Ground" of the space environment
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%, and the aging data of the materials under strong ultraviolet radiation is completely recorded. The new protective materials screened out have 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.
Agriculture and Scientific Research: The "Spectral Magician" of Cross-border Innovation
In the agricultural sector, the "spectral formula" technology of Saifan simulators 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.
In the field of scientific research, 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, 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.
Service Ecosystem: The "Reassuring Choice" with full-cycle Assurance
Saifan Optoelectronics has established a service system covering the entire life cycle of equipment. 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.
The company regularly holds "Solar Simulation Technology Training Courses" and has cultivated over 300 professional and technical talents. The wide-temperature-range test fixture customized for aerospace customers has been granted a national patent, demonstrating strong customization capabilities. At present, Saifan solar simulators have served over 200 customers worldwide. The repurchase rate of core customers has reached 82%, and 85% of new customers come from word-of-mouth recommendations.
From every percentage point increase in photovoltaic efficiency to every safe flight of spacecraft, from every scientific research breakthrough in the laboratory to every harvest in the farmland, Saifan Optoelectronics' solar simulators have always empowered innovation with precise light.
