Photovoltaic research and development: No need to "chase the sun" anymore. Data is accurate and efficiency has doubled
Liu, an engineer from a perovskite battery company, still remembers the embarrassing situation of conducting experiments in the past: "The battery efficiency measured in the morning was 25.1%, but it dropped to 23.8% in the afternoon on a cloudy day. The data was like a 'roller coaster'. Half of the time was spent repeatedly verifying, and the research and development progress was 40% slower than that of competing products." It was not until the workshop was equipped with Saifan's solar simulator that he finally no longer had to "check the weather forecast to arrange experiments".
The most reassuring feature of this device is the "ever-stable midday sunlight". The hybrid light source of "xenon lamp + LED supplementary lighting" covers the spectrum from 350nm to 1100nm perfectly. Even the near-infrared region, which is easily overlooked by traditional equipment, can achieve energy restoration accuracy of over 98%. Engineer Liu said, "When testing the same batch of batteries now, the error between today's data and the reproduction next month will not exceed 0.1%. There's no need to compete with the data anymore."
Efficiency has been improved and a large amount of costs have been saved. 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 a day, it is sufficient until retirement. 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. This year, our perovskite-silicon tandem cells have achieved mass production, and this equipment has played a significant role in this. Engineer Liu said with a smile.
Aerospace testing: No need to "wait for imported equipment", replicating "Space Light" in 7 days, no mission bottleneck
Sister Li, a space tester, once had a hard time testing the battery wings of the space station: "A 1% deviation in light intensity could make the in-orbit life assessment three years short. In the past, we could only buy imported equipment. Not only did we have to pay a deposit of 2 million yuan, but the customization cycle also took three months. We simply couldn't afford to wait for urgent tasks."
Saifan's solar simulator has brought the "space environment" into the terrestrial test room. The military-grade aluminum alloy body is equipped with 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 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 "customization speed". 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." "
Scientific research and Agriculture: Tailor-made "Light Formula", smooth experiments, good harvests
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. No matter how it is adjusted, it cannot meet the experimental requirements, and the progress of the students' papers has been slowed down."
Saifan's equipment is like a "palette of light", with 1% precision in adjusting the ultraviolet, visible and near-infrared bands. The light intensity can be adjusted from weak light on a cloudy day to strong light at noon, and it can also simulate the alternation 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. They can obtain stable data at any time, and the progress of their research has increased by 50%." "
This beam of light, when it reaches the farmland, is even more like a "harvest magic weapon". 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 visited the greenhouse to test the light and soil fertility, and customized a formula of "65% red light + 10% blue light +2 hours of ultraviolet light" for them, providing 6 hours of additional light 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, more than 10 farmers around have followed me to buy!
Not only a device, but also a "light partner" that accompanies you in innovation
Saifan knows that good equipment must be backed by good service. 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 particularly "considerate" : providing "one-on-one" training for research institutions to help teams 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 places
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. If your work is also stuck by the "light problem", this "artificial sunlight" might just be the key for you to break through the bottleneck.
