"For half a month, it has been raining continuously. The photovoltaic cell experiments in the laboratory have been suspended again and again, and the project milestones are about to be delayed." "To test the battery wings of the spacecraft, the custom-made spectral equipment from abroad has been waiting for three months but still hasn't arrived. The task team has been working overtime every day to catch up with the schedule." "The strawberries in the greenhouse are ripe, but their sweetness is three degrees lower than last year. The buyer has cut the price by half." "A year's hard work is almost in vain" - These "light anxieties" in photovoltaic research and development, aerospace testing, and agricultural planting have made countless practitioners sigh over the weather and schedules. It was not until Saifan Optoelectronics, with 20 years of accumulation in optoelectronic technology, brought the "sunlight that comes whenever you want" into workshops, laboratories and greenhouses that "no matter what the weather is like outside, experiments can be advanced and harvests are guaranteed" became the norm.
Today, this "artificial sunlight" has accompanied over 150 clients out of their predicaments: it has helped photovoltaic enterprises shorten the battery research and development cycle by half, ensured data accuracy 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 research and development: No more "chasing the sun for experiments", data is stable and progress is fast
Mr. Liu, an employee of a perovskite battery company, still remembers the embarrassing situation on a rainy day last year: "I just finished measuring a set of data in the morning, with an efficiency of 25.1%. When I measured it again on a cloudy day in the afternoon, it dropped to 23.8% directly. The data was like a roller coaster. Half a year passed, and half of it was repeatedly verified. Our competitors had already launched new products, but we were still polishing the data." At that time, the first thing he did every day at work was to check the weather forecast. "I got a headache when I saw a cloudy day, and all my experimental plans were disrupted."
It was not until the workshop was equipped with Saifan's solar simulator that Mr. Liu's "dependence on weather forecasts" was completely cured. The most worry-free thing about this device is that no matter how heavy the rain or how strong the wind is outside, the light it outputs is exactly the same as that on a midday sunny day. Saifan adopts a hybrid light source of "xenon lamp + LED supplementary lighting", covering the spectrum from 350nm to 1100nm perfectly. Even in the near-infrared region that is easily overlooked by traditional equipment, the energy restoration can be accurate to over 98%. Now, Engineer Liu feels particularly at ease when measuring the data: "The results measured today, when reproduced next month, the error will not exceed 0.1%. There's no need to argue with the data anymore." "
Efficiency has been improved and costs have been saved a lot. Previously, the monthly electricity cost for eight xenon lamp devices was 20,000 yuan. When replacing the lamps, the entire production line had to be shut down for three days, and the loss from the shutdown alone was 500,000 yuan. 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 A-grade product rate has risen from 88% to 93%, saving 12 million yuan in product losses in A year. This year, our perovskite-silicon tandem cells have been successfully mass-produced, and this equipment has made a significant contribution. When Engineer Liu said this, he was still holding the just-printed qualified data report in his hand, with a smile in his eyes.
Aerospace testing: No need to "wait for imported equipment", replicating "Space light" in 7 days, mission not delayed
Sister Li, a space tester, had many troubles when testing the battery wings of the space station before: "The in-orbit life assessment of spacecraft battery wings: A 1% deviation in light intensity could lead to a three-year error. In the past, we could only buy imported equipment, which not only required a deposit of 2 million yuan but also had a customization cycle of three months. We simply couldn't afford it during urgent tasks." " Once, in order to meet the satellite launch schedule, she and her team even considered "making do with the existing data", but in the end, they gritted their teeth and waited for imported equipment. "During that period, I couldn't sleep every day, fearing that the mission would be delayed."
Saifan's solar simulator has completely changed this situation of "passive waiting". It is like a "space light replication machine", featuring a military-grade aluminum alloy body and dual circulation water cooling. Even in extremely cold weather of -40 ℃, the device can maintain a stable temperature, 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 actual space measurement data. Even atmospheric interference can be precisely 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". Last year, the Mars exploration mission required a special spectrum of "AM0 + infrared enhancement". She contacted Saifan with a try-it-out attitude. To her surprise, the team completed the module development in just seven days, increasing the irradiance of the 800-1100nm band by 30%, which precisely matched the light on the Martian surface. "Previously, when waiting for imported equipment, one had to look at others' faces. Now, it can be used in just 7 days, and 1.5 million yuan in customization fees have been saved. The key data that the efficiency of the Mars rover's sails has increased by 22% is all measured by it." " Now, Sister Li no longer has to "jam the equipment" with her testing tasks. Even the department's urgent tasks are given priority to her.
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 by the photocatalytic hydrogen production experiment for half a year: "We need to adjust the proportion of ultraviolet light from 5% to 15%, but the traditional equipment only has three fixed Settings. No matter how we adjust it, it can't meet the experimental requirements. The progress of the students' papers has been slowed down. One graduate student was even worried that he wouldn't be able to graduate." During that period, he spent every day in the laboratory, trying to modify the circuit and change the filter, but still couldn't solve the problem.
Saifan's equipment was like a "palette of light", instantly solving this difficult problem. It supports 1% precision adjustment in the ultraviolet, visible and near-infrared bands. 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". "Nowadays, students don't have to compete for 'sunny days' when conducting experiments and can produce stable data at any time. This year, three students have completed their graduation theses ahead of schedule, and the research progress has increased by 50%." "
This "customizable light" has become a "harvest magic tool" in the farmland. 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. Last spring, the Saifan team conducted on-site research, measured the light and soil fertility of the greenhouses, and customized a supplementary lighting plan of "65% red light + 10% blue light +2 hours of ultraviolet light", providing 6 hours of supplementary light every day.
After one growing season, Lao Yang's strawberries have completely transformed: the sweetness 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 sodium lamp 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, and I have even become the "science and technology leader" in the village! Now, in Lao Yang's greenhouse, farmers come to visit every day. He even specially made dozens of copies of Saifan's equipment manual and distributed them to everyone for reference.
Not just selling equipment, but also being your "light partner" to solve problems together.
Saifan Optoelectronics knows that good equipment is not only "usable", but also "easy to use and worry-free". So they have established 7 spare parts centers across the country, with 98% of commonly used accessories in stock. They 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 scene within two hours and fixed it in three hours, not delaying the test on that day. The person in charge of the enterprise specially sent a banner to Saifan.
Moreover, the service is particularly "considerate" : providing "one-on-one" training for research institutions, helping teachers and students master spectral tuning within a week. Conduct production line linkage debugging for photovoltaic enterprises to ensure seamless integration of equipment and MES systems, eliminating the need for manual data transmission. We go to the fields for agricultural clients and adjust the "light formula" according to the growth stages of strawberries and tomatoes. We even explain clearly when to increase red light and when to add ultraviolet light. The equipment can also be calibrated for the first time for free. The core components are guaranteed for three years. There is a laboratory that has been using equipment for five years. After maintenance, the spectral matching degree is still as good as new.
The "light" of the future will help more people solve their problems
Nowadays, the "dual carbon" goals are advancing at an increasingly rapid pace, and deep space exploration and precision agriculture are also developing at an accelerated rate. Saifan Optoelectronics is still adding new capabilities to this "artificial sunlight" : it is developing a "quantum dot light source + AI calibration" system to achieve higher spectral accuracy and wider coverage bands, 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 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, and even in remote areas, they can use high-quality equipment.
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 stuck by the "lighting problem", this "light that comes whenever you want" might just be the key for you to break through the bottleneck.
