Natural sunlight, once the "default light source" for human exploration and production, has also become an "invisible barrier" restricting industry upgrading due to its "unpredictable weather", "geographical limitations" and "extreme difficulty in recovery". In the current era when photovoltaic research and development is eager for stable light, aerospace testing urgently needs space spectra, and scientific research and agriculture pursue customized light effects, Saifan Optoelectronics, based on its 20 years of accumulation in optoelectronic technology, has created a solar simulator that combines "accuracy, stability, and customization", transforming into a "wall-breaking leader" of light and breaking the shackles of natural light. Open up a brand-new track of "active control of light" for all fields.
In the photovoltaic field: Leading the "accelerated run" of high-efficiency battery research and development with "ultimate light efficiency"
It has been overcast for a week in a row. The test data of perovskite solar cells has been fluctuating like a roller coaster. When the sun finally comes out, the light intensity fluctuates. The research and development progress in half a year has only been completed by 30%. The teasing remarks of the R&D director of a leading photovoltaic enterprise reveal the common predicament of the industry. The "uncontrollability" of natural light has trapped the research and development of high-efficiency batteries in a "passive waiting" deadlock. It was not until the emergence of the Saifan solar simulator that the situation was completely reversed.
As the "wall-breaking leader" of light, Saifan Simulator redefines the photovoltaic testing standards with "millimeter-level precision" It covers the full spectrum from 400nm to 1100nm and is equipped with the self-developed 6th generation intelligent spectral fitting algorithm (trained with 200,000 sets of natural spectral data). The spectral matching degree has exceeded the upper limit of A + level (0.9-1.1). Even the subtle energy fluctuations in the near-infrared band from 780 to 1100nm can be precisely replicated. Make the simulated lighting "zero difference" from the real sunlight. What is even more commendable is its "ultra-stable output" capability - a light intensity fluctuation rate of ±0.2% per hour (30% higher than the industry standard), which is equivalent to a continuous 24-hour test where the light intensity change does not exceed the "brightness of firefly light emission". The spatial uniformity of ±1.8% ensures that every inch of the battery cell receives uniform light, and the data deviation is strictly locked within 0.8%.
With this "light efficiency weapon", the R&D team of the enterprise identified the battery efficiency bottleneck in just 15 days: the absorption efficiency in the near-infrared band was 12% lower than expected. By optimizing the material structure, the conversion efficiency of perovskite/silicon tandem cells has exceeded 28.5% at one go. The related achievements have been published in Nature Energy, and the research and development cycle has been shortened by 65% compared with the industry average. In the mass production stage, an intelligent testing production line composed of 12 Saifan simulators completed battery performance testing at A speed of 80 cells per minute. The A-grade product rate soared from 86% to 96%, reducing defective product losses by over 25 million yuan annually. This has driven the proportion of high-efficiency battery production capacity of the enterprise to increase to 40%, leading the wave of photovoltaic technology iteration.
In the aerospace field: Building a "safety defense line" for deep space exploration with "extreme light conditions"
The lighting environment that spacecraft face in space is something that traditional ground equipment would never dare to imagine - the extreme cold of -183 ℃ on the lunar surface and 14% of Earth's light intensity, as well as the special spectrum filtered by the Martian atmosphere. Any simulation deviation could lead to mission failure. The words of the chief engineer of a certain academy of China Aerospace Science and Technology Corporation highlight the extreme requirements for light simulation in aerospace testing. The solar simulator of Saifan Optoelectronics is precisely the "key force" that breaks through the barrier of "extreme light conditions being difficult to reproduce".
The core advantage of Saifan as the "wall-breaking leader" lies in its "extreme adaptability to all scenarios" : For the lunar exploration mission, the "AM0 Spectrum + ultra-low temperature adaptation" module was developed within 72 hours. Through military-grade titanium alloy to strengthen the body and vacuum insulation design, the equipment can operate stably within the extreme temperature range of -200 ℃ to 80℃, with light intensity fluctuations of no more than ±1.2%, perfectly reproducing the strong radiation and low light environment on the lunar surface. During the continuous 1,000-hour simulation test, the aging pattern of the solar cell wing material of the spacecraft was accurately captured, which helped the team develop a new type of anti-radiation coating, extending the in-orbit life of the cell wing by 8 times and providing a "double insurance" for the safety of the power system of the manned lunar landing project.
Facing the special demands of Mars exploration, the Saifan team has demonstrated "leading capabilities" : based on the data of Mars' atmospheric composition, they completed the customization of "spectral filtering algorithm upgrade + infrared band enhancement" within five days, increasing the irradiance in the 800-1100nm band by 35% and precisely restoring the light characteristics of the Mars surface. The solar panels of the Mars rover optimized by this equipment have increased the power generation efficiency by 30% in the weak light environment of Mars, completely solving the "energy endurance" problem of deep space exploration and providing core technical support for China's Mars exploration mission.
Scientific Research and Agriculture: Unlocking the "Infinite Possibilities" of Cross-border Innovation with "Customized Spectra"
When we study "light-controlled plant gene expression", we need to adjust the proportion of ultraviolet, visible and near-infrared bands at different times every day. The traditional simulator's "fixed spectrum" mode is like putting a "shackle" on the experiment. The problem of a researcher from a certain institute of Botany of the Chinese Academy of Sciences was easily solved by the Saifan solar simulator. As the "wall-breaking leader" of light, Saifan simulators, with their "all-dimensional customization" capabilities, have opened up a new window of innovation for the fields of scientific research and agriculture.
On the scientific research end, it is a "spectral magician" : the ultraviolet-visible and near-infrared bands support 0.5% precision adjustment, the light intensity can be freely switched from 0.05sun to 3sun, and it can also simulate dynamic lighting scenarios such as solar eclipses, day-night alternations, and seasonal changes, and even output nanosecond-level pulse light. With this capability, the team from the Institute of Botany successfully discovered that 12 hours of exposure to a specific blue light band (450nm) could increase the expression level of rice lodging resistance genes by 200%. The related achievements provide a brand-new direction for the breeding of stress-resistant crops. In the field of photocatalysis, a team from a certain university has increased the efficiency of CO₂ reduction to methanol by 60% through a "UV + near-infrared synergistic illumination" solution customized by the Saifan simulator, providing key support for breakthroughs in carbon neutrality technology.
In the agricultural sector, it has transformed into a "light manager for increasing production" : In a citrus planting base in Taizhou, Zhejiang Province, due to insufficient winter sunlight, the sugar content of the fruits was only 10%, and the yield per mu was less than 3,000 jin. The Saifan technical team has customized an intelligent lighting solution of "70% red light + 15% blue light + 5% ultraviolet light" based on the photosynthesis characteristics of citrus fruits, and realizes dynamic adjustment of light intensity and duration through the Internet of Things system. After one growing season, the sugar content of citrus fruits has increased to 15%, the yield per mu has exceeded 4,000 jin, and the price per jin has risen from 3 yuan to 6 yuan. The annual income of the 200-mu base has increased by more than 1.2 million yuan. Nowadays, "Saifan Customized Light" has become a "golden brand" for the upgrading of local agriculture, leading over 50 households in the surrounding areas onto the path of "light control for increased income".
Full-cycle empowerment: With "partner-style services", we safeguard the continuous growth of the industry
Saifan Optoelectronics is well aware that the responsibility of a "leader" lies not only in providing high-quality equipment but also in empowering customers' growth throughout the entire process. For this reason, Saifan has established a "full-cycle partner-style service system" : 10 regional technical centers across the country, equipped with a professional service team of over 50 people, providing 7× 24-hour response, arriving at the scene within 4 hours for equipment failure and repairing within 24 hours. For research institutions, the "Optical Simulation Technology Training Course" is launched, cultivating over 200 professional talents each year. We provide "equipment full life cycle management" for enterprise customers, regularly conducting performance calibration and consumable replacement to ensure that the equipment remains in the best operating condition for a long time.
After a certain new energy enterprise introduced the Saifan simulator, the Saifan team not only provided installation and commissioning services but also continuously tracked the equipment operation data. Three months later, they found that there was room for optimization in the production line testing efficiency and proactively visited to upgrade the algorithm, which increased the testing speed by 15%. This "proactive empowerment" service philosophy has enabled Saifan to win the deep trust of its customers - the repurchase rate of core customers has reached 90%, and 95% of new customers come from referrals by existing customers, forming a dual advantage pattern of "technology leadership + service protection".
From the iterative breakthroughs in photovoltaic technology to the steady progress in space exploration, from cross-border innovation in the scientific research field to the quality improvement and income increase in the agricultural industry, Saifan Optoelectronics' solar simulators have always been the "leader in breaking the wall of light", breaking the boundaries of natural light and leading various industries into a new era of "actively controlling light and efficiently utilizing light". In the future, Saifan will continue to delve deeply into optical simulation technology, providing more precise, stable and intelligent products to help more industries break through innovation bottlenecks and write more development miracles in the "era of light control".
