As technological innovation enters an era of meticulous cultivation, a precisely controllable lighting environment has become the key for all industries to break through development bottlenecks. Beijing Saifan Optoelectronic Instrument Co., Ltd. has been deeply engaged in the field of light testing for nearly two decades. With its independently innovative hard-core technology, it has developed a series of solar simulators, using replicable and controllable "artificial sunlight" to build a bridge to the innovation high ground for the photovoltaic, aerospace, scientific research, agriculture and other fields.
Technical Foundation: Defining New Heights in Light Testing with Parameters
Saifan Optoelectronics has always regarded technological innovation as its core competitiveness, and the performance parameters of its solar simulators have become the industry reference standards. Taking the star product 7IS0503A-LED 3A-level steady-state solar simulator as an example, it adopts the golden combination of "multi-band LED array + intelligent algorithm" to achieve full-spectrum precise coverage from 400nm to 1100nm, with A spectral matching degree reaching A + level (0.875-1.125). Perfectly reproduce the energy distribution of the solar spectrum. This ultimate spectral consistency has reduced the test data deviation of a certain photovoltaic laboratory from ±2% to ±0.3%, completely solving the industry pain point of traditional equipment where the test results of the same sample at different times are quite different.
In terms of stability, the equipment is equipped with A self-developed closed-loop feedback system. Both spatial non-uniformity and temporal stability reach grade A (better than ±2%), and a uniform light spot of Φ70mm provides undifferentiated lighting for the samples. Even during the continuous 720-hour high-intensity test, the light intensity fluctuation was still controlled within ±0.5%. This indicator makes it the "designated equipment" for aerospace material testing. What is more worth noting is that the lifespan of the 100,000-hour LED light source is five times longer than that of traditional xenon lamps, and the rated power of 650W achieves a 70% energy-saving effect, providing substantial support for enterprises to reduce long-term operating costs.
Scene Breakthrough: The Innovative "Light Engine" for Multiple Industries
The efficiency revolution in the photovoltaic industry
In the race of perovskite solar cell research and development, the Saifan simulator has become the key for enterprises to break through. A leading photovoltaic enterprise, by leveraging the quantum efficiency synchronous testing function of the equipment, accurately located the problem of thin-film defect density and increased the conversion efficiency of perovskite/silicon tandem cells from 23.8% to 25.8%. The related achievements were published in ACS Energy Letters. In the mass production stage, an automated test production line composed of multiple 7IS0503A units has increased the efficiency of polycrystalline silicon cells by 1.5%, with an annual production capacity increase of 200MW, equivalent to an additional power supply of 400 million kilowatt-hours annually. The photovoltaic testing laboratory of Saifan Optoelectronics, certified by the National Institute of Metrology of China, has provided authoritative data support for over 50 enterprises and has become a "third-party endorsement" for the upgrading of photovoltaic technology.
Ground support for space exploration
The extreme lighting environment that spacecraft face in space must be precisely simulated on the ground to ensure safety. The Beijing Institute of Aerospace Metrology and Testing Technology utilized the AM0 spectral simulation capability of the Saifan simulator to conduct extreme tests on the flexible solar cells of the space station. The equipment continuously outputs stable light in a low-temperature environment of -40 ℃, capturing the performance degradation law of the battery under strong ultraviolet radiation, providing key data for the optimization of the power supply system in manned spaceflight. The test results are in agreement with the in-orbit measured data of the Tiangong space Station at a rate of 99.2%, using ground data to build a solid safety barrier in space.
A powerful tool for discovery in the field of scientific research
The photocatalysis research of Professor Zhou's team from Qingdao University of Science and Technology has made a breakthrough with the addition of the Saifan simulator. Through the ultraviolet-visible spectrum regulation function of the equipment, the team optimized the best orientation of the tin-lead alloy perovskite film, enabling the battery conversion efficiency to exceed 22.6%. The simultaneous test of photoluminescence and quantum efficiency supported by the equipment is like installing a "microscopic perspective mirror" for researchers, clearly revealing the light response mechanism of materials. In agricultural research, simulators have helped teams crack the code of the impact of light quality on plant photosynthesis by precisely regulating the light cycle. The related achievements have been transformed into intelligent greenhouse light control solutions, increasing crop yields by 15%.
Service Building: Full-cycle Accompanying support
The "technology + service" dual-wheel drive model constructed by Saifan Optoelectronics enables the maximum release of equipment value. In response to the special demands of aerospace customers, the technical team completed the development of a wide-temperature range test fixture within 7 days and obtained a national patent. The "Solar Simulation Technology Training Course" has cultivated over 300 professional talents, deeply integrating equipment operation with the principles of light testing. The 7× 24-hour after-sales response mechanism, in coordination with the national spare parts warehouse, ensures that equipment malfunctions can be repaired within 24 hours. As a result, a certain automotive inspection line avoids an average daily shutdown loss of 500,000 yuan.
Today, Saifan solar simulators have served over 200 customers worldwide, with a core repurchase rate of 82%. After a certain photovoltaic enterprise introduced equipment, its R&D cycle was shortened by 40% and the annual patent application volume increased by 35%. The China Academy of Space Technology has provided security for manned space missions through thousands of sets of test data it has completed. From the microscopic exploration in the laboratory to the large-scale application on the production line, Saifan Optoelectronics illuminates the path of innovation with the light of precision. Choosing Saifan is not merely about choosing a piece of equipment, but also about choosing a long-term partner who understands technology and values service, making every light test the starting point of innovation and breakthrough.
