Light is the source of energy in nature and the core driving force for technological breakthroughs. In fields such as photovoltaics, aerospace, agriculture, and scientific research, precise and controllable light simulation technology has become a key support for promoting innovation. With 20 years of technological accumulation, Beijing Saifan Optoelectronics has developed a solar simulator. With military-grade precision performance, all-scenario adaptability and profound industry insight, it has become a trusted "light testing expert" in various fields, using the light of technology to give wings to innovation in multiple industries.
Hardcore technology sets a benchmark for optical testing performance
The core competitiveness of Saifan Optoelectronics' solar simulator stems from its ultimate pursuit of technology. Its star product, the 7IS0503A-LED 3A-level steady-state solar simulator, adopts a hybrid light source architecture of "xenon lamp + LED supplementary lighting", achieving precise coverage of the full spectrum from 400nm to 1100nm. The independently developed 5th generation intelligent spectral fitting algorithm, trained on 100,000 sets of natural spectral data, achieves A spectral matching degree of A + level (0.875-1.125), with a spectral consistency deviation of no more than 1% at each point, perfectly reproducing multiple types of standard spectra such as AM0 and AM1.5G.
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 closed-loop feedback system. The light intensity fluctuation rate is strictly controlled within ±0.3% per hour, and the spatial uniformity is better than ±2%, far exceeding the industry average. The military-grade 6061-T6 aluminum alloy body adopts a design where the optical chamber and the transmission chamber 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 equipment for aerospace systems. The lifespan of the LED light source is up to 100,000 hours, which is five times longer than that of traditional xenon lamps. The overall power consumption of the machine is only 650W, saving over 70% of energy and significantly reducing the long-term usage cost.
In-depth exploration in multiple domains to unlock the application value of light testing
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. A leading photovoltaic enterprise, by leveraging the full-band detailed regulation function of the equipment, discovered the absorption shortcoming of perovskite cells in the near-infrared band of 780-1100nm. After optimization, the conversion efficiency of the cells 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 12 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, reducing annual losses by over 12 million yuan.
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 testing services such as spectral response and I-V characteristics for over 50 enterprises, contributing to an average annual growth rate of 35% in patent applications for its clients. It has become an "incubator" for photovoltaic technology innovation.
Aerospace field: Ground safety barrier for space exploration
Spacecraft face the test of extreme light in space, and the Saifan simulator has become the "space rehearsal ground" for ground tests. The China Academy of Space Technology used its precisely reproduced AM0 spectrum to conduct a 720-hour low-temperature irradiation test on the flexible solar cell wings of the space station. The light intensity fluctuation of the equipment in an environment of -40 ℃ is ≤±1.2%, capturing the aging law of materials under strong ultraviolet radiation. The new protective materials screened out have extended the service life of spacecraft coatings by three times, providing solid data support for the manned space program.
In the Mars exploration mission, the Saifan special team completed the development of the "AM0 + 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 test data have increased the power generation efficiency by 22%, ensuring a stable energy supply for the exploration mission.
Scientific Research and Agriculture: A Cross-disciplinary Innovation Source of Optical Power
Professor Zhou's team 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 and photoluminescence, 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, Saifan's "Spectral formula" technology has brought about a quality revolution. By adjusting the proportion of 35% blue light and ultraviolet auxiliary light, the anthocyanin content of the blue roses cultivated in the Yunnan flower base has increased by 22%, the flowering period has been extended by 7 days, and the market premium has reached 30%. The Shandong Strawberry Cooperative has adopted a red light-dominated spectral scheme, achieving a 2-degree increase in sweetness and a 150-kilogram increase in yield per mu. The 20-mu base has seen an annual income increase of over 160,000 yuan, making "light fertilization" a reality.
Service closed loop, building a full-cycle guarantee system
Saifan Optoelectronics has established a service ecosystem covering the entire life cycle of equipment. Seven regional spare parts centers across the country stock over 95% of commonly used components. The service commitment of "7× 24-hour response + 48-hour on-site service" ensures rapid repair of equipment failures. When a certain vehicle inspection line suddenly broke down, engineers arrived at the scene within two hours and resumed operation within four hours, avoiding a production halt loss of 500,000 yuan per day.
The company regularly holds "Solar Simulation Technology Training Courses" and has cultivated over 300 professional talents. The wide-temperature-range test fixture customized for aerospace customers has been granted a national patent, demonstrating strong customization capabilities. At present, Saifan Simulator has served over 200 customers worldwide, with a core repurchase rate of 82% and 85% of new customers coming from word-of-mouth recommendations.
From breakthroughs in photovoltaic efficiency to aerospace security, from scientific research innovation to agricultural quality improvement, Saifan Optoelectronics' solar simulators, with their technological strength and in-depth industry experience, continuously create value for various fields. After a certain photovoltaic enterprise introduced the equipment, its R&D cycle was shortened by 40%, and the test data from aerospace customers matched the actual measurement in orbit by 99.2%. Choosing Saifan means choosing to walk alongside the leaders in the field of light testing, allowing the light of precision to illuminate the path of innovation and reaping tangible technological breakthroughs and industrial upgrading achievements.
