"Outside the window, it's raining again. This week's photovoltaic experiment has to be postponed once more." "The custom-made space spectral equipment from abroad hasn't arrived yet, so the space test has to be put on hold." "The strawberries in the greenhouse are ripe, but they are not sweet enough to sell at a good price. This year's harvest is in doubt." - These "light problems" in photovoltaic research and development, space testing, and agricultural planting have made countless people sigh at the weather. It was not until Saifan Optoelectronics, with 20 years of optoelectronic technology, brought the "sunlight that comes whenever you want" into workshops, laboratories and greenhouses that "experiments can be carried out and harvests can be guaranteed regardless of the weather" became the norm.
Today, this "artificial sunlight" has helped over 150 clients out of their predicaments: it has accelerated the battery research and development of photovoltaic enterprises by half, ensured data for 12 national-level space missions, assisted research teams in publishing over 20 papers in SCI, and also enabled Shandong strawberry grower Lao Yang to earn 200,000 yuan from his 20 mu of land in over a year.
Photovoltaic professionals no longer have to "chase the sun for experiments". With stable data and faster progress, they can make progress
Mr. Liu, an engineer from a perovskite battery company, was previously constantly tormented by experimental data: "The battery efficiency measured in the morning was 25.1%, but it dropped to 23.8% on a cloudy day in the afternoon. The data fluctuated up and down. For half a year, we were repeatedly verifying it. Our competitors had already launched new products, but we were still honing our data." " It was not until the workshop was equipped with Saifan's solar simulator that he no longer had to check the weather forecast every day to arrange experiments.
The most worry-free feature of this device is that "it's always sunny at noon". No matter how windy or rainy it is outside, the light it outputs is very stable - it covers the entire spectrum from 350nm to 1100nm. Even in the near-infrared region that traditional devices tend to overlook, the energy restoration can be accurate to over 98%. Engineer Liu feels particularly at ease when measuring data now: "The result measured today will have an error of no more than 0.1% when measured next month. I no longer have to struggle with the data."
Efficiency has been improved and costs have been saved a considerable amount. Previously, the monthly electricity cost for eight xenon lamp devices was 20,000 yuan, and the entire line had to be shut down for three days when the lamps were replaced. Now, Saifan equipment saves 70% of electricity. 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 a day, it is enough until retirement. Even more surprisingly, the automated testing line can screen 60 batteries per minute, and the rate of good products has risen from 88% to 93%, saving 12 million yuan in losses from defective products in a year. This year, our perovskite-silicon tandem cells can be put into production, and this equipment has made a significant contribution. When Liu Gong said this, his eyes were filled with smiles.
Aerospace testing does not require "waiting for imported equipment". Replicating "space light" in just 7 days ensures that the mission is not delayed
Sister Li, a space tester, was once worried about testing the battery wings of the space station: "A 1% deviation in light intensity could cause a three-year delay in the satellite's life assessment. In the past, we could only buy imported equipment, which not only required a deposit of 2 million yuan but also a three-month wait. We simply couldn't afford it during urgent tasks." "
Saifan's solar simulator directly brings the "space environment" to the laboratory. The military-grade body and dual circulation water cooling ensure that even in extremely cold weather of -40 ℃, the equipment can maintain a stable temperature, with a spectral output difference of no more than 0.5%. When simulating the AM0 spectrum in space, it is calibrated with 200,000 sets of actual space measurement data. Even atmospheric interference can be eliminated, and the irradiance error is controlled within 1%, which is no different from real space light.
What surprised Sister Li the most was the "customization speed". The Mars exploration mission requires a special spectrum of "AM0 + infrared enhancement". The Saifan team completed the module in just 7 days, increasing the light intensity in the 800-1100nm band by 30%, which precisely matches the illumination on the Martian surface. "Previously, when waiting for imported equipment, one had to look at others' faces. Now, it can be used in just seven days and has saved 1.5 million yuan. The key data that the efficiency of the Mars rover's sails has increased by 22% is all measured by it." "
Both scientific research and agriculture can "customize light". When experiments go smoothly, harvests will be good
Professor Zhou from Qingdao University of Science and Technology was held back for half a year by 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. No matter how you adjust it, it's not right. The progress of the students' papers has been slowed down."
Saifan's equipment is like a "palette of light", extremely flexible - it can adjust the ultraviolet, visible and near-infrared bands with 1% precision, and the light intensity can be selected from weak light on a cloudy day to strong light at noon. It can also simulate the alternations of day and night and pulsed light. After Professor Zhou's team adjusted the proportion of ultraviolet light to 15%, the hydrogen production efficiency increased by 40% at once, and the paper was successfully published in "Applied Catalysis B: Environmental". "Now students can conduct experiments at any time without having to rush for the 'sunny window', and their research progress has increased by 50%." "
This beam of light, when it reaches the farmland, is even a "helper for a bountiful harvest". 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. After a year of hard work, he didn't make much profit. Later, the Saifan team came to the site, measured the light and soil conditions of the greenhouse, and customized a plan of "65% red light + 10% blue light +2 hours of ultraviolet light", providing 6 hours of additional light every day.
After one growing season, Lao Yang's strawberries have changed: the sweetness has risen to 11 degrees, the anthocyanin content has 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, more than 10 farmers around me are following me to buy equipment from Saifan!
Not just selling equipment, but also being your "light partner" to solve problems together.
Saifan knows that good equipment requires good service. With 7 spare parts centers across the country, 98% of commonly used accessories are in stock. We promise a 24-hour response and on-site service within 48 hours. Once, the equipment of a certain photovoltaic enterprise suddenly broke down. The engineer arrived at the site within two hours and fixed it in three hours, without delaying the test of the same day.
Moreover, the service is particularly "to my taste" : providing "one-on-one" training for research institutions and helping teachers and students master spectral tuning within a week. Conduct production line commissioning for photovoltaic enterprises to ensure seamless connection between equipment and production lines. 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 be calibrated for the first time for free. The core components are guaranteed for 3 years. There are laboratory devices that have been used for 5 years and still have the same accuracy as new after maintenance.
The "light" of the future will help more people solve their problems
Nowadays, the "dual carbon" goals are advancing rapidly, and deep space exploration is also accelerating. Saifan is still adding new capabilities to this "light" : it is developing "quantum dot light sources + AI calibration" to make the spectrum more accurate and have a wider coverage, meeting the testing requirements of the next generation of batteries and space materials. It is necessary to develop special models that can withstand high pressure and radiation to assist in deep-sea exploration and lunar base energy measurement. 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 scientific research breakthroughs in the laboratory to efficiency improvements on the production line and the joy of harvest on the ridges of the fields, Saifan Optoelectronics has used 20 years of technology to turn "controllable light" into an "innovation helper" for various industries. If your work is also trapped by "light", this "light that comes whenever you want" might just be the key for you to break through the bottleneck.
