It has been raining for a week in a row, and all the perovskite battery experiments in the laboratory have come to a halt. It seems that the project schedule is about to be delayed. To test the solar panels of the Mars rover, we sought to customize spectral equipment from abroad, but after waiting for three months, there has been no news. The strawberries in the greenhouse are growing well, but due to insufficient light, their sweetness has dropped by 3 degrees. The "light anxiety" hidden in photovoltaic research and development, aerospace testing, and agricultural planting, such as the acquisition price being directly halved, once left countless practitioners at a loss. It was not until Saifan Optoelectronics, with 20 years of accumulation in optoelectronic technology, brought the "obedient sunlight" into laboratories, test rooms and greenhouses that everything began to change.
Today, this "artificial sunlight" has accompanied over 200 clients on their path of innovation: Helping photovoltaic enterprises shorten the battery research and development cycle by 60%, ensuring data accuracy for 12 national-level space missions, enabling over 20 papers of the research team to be published in SCI, and also allowing Shandong strawberry grower Lao Yang to earn over 200,000 yuan from his 20 mu of land in a year.
Photovoltaic workers no longer need to "experiment based on the weather", and they have won in both efficiency and cost
Liu, an engineer from a leading photovoltaic company, once couldn't sleep over the experimental data: "The efficiency of the perovskite battery measured in the morning was 25.1%, but it dropped to 23.8% on a cloudy day in the afternoon. Half of the year was spent repeatedly verifying the data, and the research and development progress was as slow as a snail." He didn't breathe a sigh of relief until Saifan's solar simulator was installed in the workshop.
The most reassuring feature of this device is that it can stably output "sunny light" no matter how windy or rainy it is outside. The hybrid light source of "xenon lamp + LED supplementary lighting" can cover the spectrum from 350nm to 1100nm without any problem. Even the near-infrared region, which is easily overlooked by traditional equipment, can achieve energy restoration accuracy of over 98%. Engineer Liu said, "The data measured today will have a reproduction error of no more than 0.1% next month. There's no need to argue with the data anymore."
Efficiency has been improved and costs have been reduced significantly. Previously, the monthly electricity cost for eight xenon lamp devices was 20,000 yuan, and the entire production line had to be shut down for three days when the lamps were replaced. Now, the power consumption of Saifan equipment has been reduced by 70%. A 1GW production line can save 200,000 yuan in electricity fees annually. The LED light source can be used for 100,000 hours without replacement - calculated at 8 hours per day, it can last for 34 years. Even more surprisingly, the automated test line can screen 60 batteries per minute, and the A-grade product rate has risen from 88% to 93%, reducing the cost of 12 million defective products in A year. "Now we have the final say on the pace of our research and development. This year, we can advance the mass production of perovskite-silicon tandem cells, which was something we never dared to imagine before." " Engineer Liu said with a smile.
Aerospace testing doesn't require "waiting for imports"; it can replicate "space light" in just 7 days.
Sister Li, a space tester, still remembers that in the past, to test the battery wings of spacecraft, they could only rely on imported equipment: "A 1% deviation in light intensity could make the in-orbit life assessment three years short. Imported equipment not only requires a deposit of 2 million yuan, but also has a customization cycle of three months. In case of urgent tasks, it's simply impossible to wait."
Saifan's solar simulator has brought "space light" into the terrestrial test room. With a military-grade aluminum alloy body and dual circulation water-cooled temperature control, the device can maintain a stable temperature even in an extremely cold environment of -40 ℃, with a spectral output deviation of no more than 0.5%. When simulating the AM0 spectrum in space, it is calibrated with 200,000 sets of measured data from space, and even atmospheric interference can be precisely eliminated, with irradiance error controlled within 1%.
What impressed Sister Li the most was the speed of customization. During the Mars exploration mission, a special spectrum of "AM0 + infrared enhancement" was required. The Saifan team completed the module development in just 7 days, increasing the irradiance in the 800-1100nm band by 30%, which precisely matches the light on the Martian surface. "Previously, when waiting for imported equipment, we had to look at others' faces. Now, we can get usable equipment in just 7 days and save 1.5 million yuan in customization fees. The key data that the efficiency of the Mars rover's sails has increased by 22% is all measured by it." "
The "light formula" of scientific research and agriculture has provided direction for both innovation and harvest
Professor Zhou from Qingdao University of Science and Technology was stuck for half a year for the photocatalytic hydrogen production experiment: "The proportion of ultraviolet light needs to be adjusted from 5% to 15%, but the traditional equipment only has three fixed Settings, and no matter how it is adjusted, it cannot meet the experimental requirements." Saifan's equipment is like a "palette of light". The ultraviolet, visible and near-infrared bands can be adjusted with 1% accuracy. The light intensity can be adjusted from the weak light on a cloudy day to the strong light at noon. It can also simulate the transition between day and night and pulsed light. Professor Zhou's team finally increased the hydrogen production efficiency by 40%, and the paper was successfully published in "Applied Catalysis B: "Environmental.
This beam of light, when it reached the farmland, even became a "harvest magic tool". Lao Yang, a strawberry grower in Shandong Province, used to rely on the weather for supplementary light in winter. The sweetness of his strawberries was only 8 degrees, and they were sold at 6 yuan per jin. Now, the Saifan team has conducted on-site research and customized a formula of "65% red light + 10% blue light +2 hours of ultraviolet light" for them, providing 6 hours of light supplementation every day. After one growing season, the sweetness of strawberries has risen to 11 degrees, anthocyanins have increased by 18%, the yield per mu has increased by 150 kilograms, and they can be sold for 12 yuan per jin. The monthly electricity bill is only 360 yuan, which is 70% less than the previous supplementary lighting. With 20 mu of land, I can earn an additional 200,000 yuan a year. Now, farmers from the surrounding areas all come to me to learn from me.
Not only a device, but also a "light partner" that accompanies you in innovation
Saifan knows that good equipment needs reliable service as a foundation. There are 7 spare parts centers across the country, with 98% of commonly used accessories in stock. We promise a 24-hour response and repair within 48 hours. Once, a certain photovoltaic enterprise experienced a sudden equipment failure. Engineers arrived at the site within two hours and resumed production within three hours, without delaying the tests of the day.
For different clients, the service is also specially "tailor-made" : providing "one-on-one" training for research institutions to help the team master spectral regulation within a week; Conduct production line linkage debugging for photovoltaic enterprises to ensure seamless integration of equipment and MES systems. Go to the fields for agricultural customers and adjust the "light formula" according to the growth stages of strawberries and tomatoes. The equipment can also enjoy the first free calibration. The core components are guaranteed for 3 years. For equipment that has been used in the laboratory for 5 years, the spectral matching degree can still be maintained at A + level after maintenance.
The "light" of the future will illuminate more unknowns
Today, as the "dual carbon" goals are advancing and deep space exploration is accelerating, Saifan is still adding new skills to "artificial sunlight" : it aims to develop "quantum dot light sources + AI calibration" to enhance spectral accuracy and cover a wider band, meeting the testing requirements of next-generation batteries and space materials. It is necessary to develop special models that can withstand high pressure and radiation to test energy for deep-sea exploration and lunar bases. We also need to reduce energy consumption by another 15% and develop a "light testing cloud platform" to enable global customers to share precise light resources.
From the scientific research breakthroughs in the laboratory, to the efficiency revolution on the production line, and then to the joy of harvest in the fields, Saifan Optoelectronics has used 20 years of technology to turn "controllable light" into an innovation accelerator for various industries. In the future, this beam of light will continue to illuminate more unknowns, accompanying every person with an innovative dream to turn the "impossible" into the "possible".
