Wang, a photovoltaic engineer, no longer needs to keep an eye on the weather forecast to arrange experiments. Li, a space tester, no longer has to stay up all night over the "difficulty in replicating space light". Professor Zhang, an agricultural researcher, can finally precisely control the light environment of crops. The "light problem" that once plagued various industries has all turned into "innovation opportunities" in front of the solar simulator of Saifan Optoelectronics. Having been deeply engaged in the optoelectronics industry for two decades, Saifan uses a device that "understands user needs" to make "controllable light" a reliable partner for every striver.
Wang Gong's "R&D Accelerator" : Full spectrum coverage from 350 to 1100nm, Enabling efficiency breakthroughs to be "one step ahead"
"Previously, when testing perovskite solar cells, the morning data was 23.2%, but it dropped to 21.5% in the afternoon on a cloudy day. The research and development progress in half a year was only 30% completed." " The photovoltaic enterprise where Engineer Wang works once fell into a "data puzzle" due to fluctuations in natural light. It was not until the introduction of the Saifan solar simulator that the situation completely reversed.
The "hardcore strength" of this device is obvious to the naked eye: The spectrum covers 350nm-1100nm, not only including the core 400-1100nm band of photovoltaic testing, but also extending to the ultraviolet region. Under the IEC 60904-9 standard, the spectral matching degree reaches A + level, accurately reproducing the AM1.5G solar spectrum. Even the 0.5% absorption difference of the battery in the near-infrared band of 780-1100nm can be captured. After eight consecutive hours of testing, the light intensity fluctuation rate remained stable at 0.08% (lower than the industry average of 0.3%). Engineer Wang stated straightforwardly, "The data measured today will have an error of no more than 0.1% when reproduced next week. There's no need to waste time on 'data validity' anymore."
What surprised the team even more was the intelligent testing system of the equipment: the built-in IV curve analysis software can generate real-time reports on 12 core parameters such as conversion efficiency and fill factor. What originally took three days for material comparison testing can now be completed in just one day. With its help, the team identified the shortcoming of near-infrared absorption in the battery, increasing the efficiency of perovskite batteries from 23% to 27.5%, shortening the research and development cycle by 60%, and rapidly advancing the related achievements to pilot production. "With this Saifan device, let's focus all our energy on technological breakthroughs. This is the right pace for research and development!" " Engineer Wang sighed.
Sister Li's "Aerospace Safety Lock" : Stably operates from -40℃ to 60℃, replicating space light "without the slightest deviation"
"Even a 1% difference in light intensity data during spacecraft battery wing tests could cause a three-year deviation in the in-orbit life assessment." " Sister Li, a space tester, was once worried that traditional simulators "couldn't withstand extreme environments" : when simulating the low temperature of -40 ℃ in space, the light intensity of the equipment drifted by more than 5%, making it impossible to verify the weather resistance of materials at all.
The "extreme adaptability" of the Saifan simulator has become a "reassuring factor" for aerospace testing: it adopts a military-grade 6061-T6 aluminum alloy body and is equipped with a dual-circulation water-cooled temperature control system, which keeps the operating temperature fluctuation of the equipment within ±0.3℃. Even in extreme environments ranging from -40 ℃ to 60℃, the spectral output deviation is still ≤±0.5%. For the space AM0 spectrum (solar radiation without atmospheric filtering), the equipment is calibrated through 200,000 sets of space spectral data, which can precisely eliminate atmospheric interference and restore the pure radiation characteristics of the sun in the universe, with the irradiance error controlled within ±1%.
During the 720-hour aging test of the battery wing of the space station, the Saifan simulator continuously output stable light, with the light intensity fluctuation always ≤0.1%, and completely recorded the aging curve of the material under strong ultraviolet rays and extremely low temperatures. Based on these data, the team developed a new type of anti-radiation coating, which extended the in-orbit lifespan of the battery wing from 5 years to 15 years. "With this Saifan device, we can finally '1:1 replicate' space lighting. Every test is full of confidence!" " Sister Li said. In the Mars exploration mission, the Saifan team customized the "Infrared Enhancement module" in just 7 days, increasing the irradiance in the 800-1100nm band by 30%, perfectly reproducing the Martian light, and helping to increase the power generation efficiency of the Mars rover's solar panels by 22%.
Professor Zhang's "Agricultural Production Increase Treasure" : 1% Precision Light Quality Control, Turning "Light Formula" into "Golden Harvest"
"Strawberries are not sweet enough not because of insufficient fertilizer, but because they haven't been adequately exposed to light." " Professor Zhang, an agricultural researcher, was once worried that facility agriculture was "dependent on the weather" : Traditional supplementary lights only had a fixed spectrum, and studying "the impact of light quality on crops" was like "shooting arrows blindfold".
The "customization capability" of the Saifan simulator has enabled Professor Zhang to open a new door to "light-controlled agriculture" It supports 1% precision adjustment in the ultraviolet (350-400nm), visible (400-760nm), and near-infrared (760-1100nm) bands. The light intensity can be freely switched from 0.1sun (equivalent to overcast light) to 2sun (equivalent to midday strong light), and it can also simulate the light cycle of day and night alternations and seasonal changes. Even output special modes such as pulsed light.
Through thousands of experiments, Professor Zhang has explored the "optimal light formula" for strawberries: red light accounts for 65%, blue light accounts for 10%, and two hours of 380nm ultraviolet light is supplemented daily (to promote anthocyanin synthesis). The strawberry greenhouses in Shandong that were renovated according to this plan have seen the sweetness of strawberries increase from 8 degrees to 11 degrees, the anthocyanin content rise by 18%, the yield per mu increase from 2,000 kilograms to 2,150 kilograms, and the selling price per jin rise from 8 yuan to 12 yuan. The 20 mu of land have seen an annual income increase of over 200,000 yuan. "Previously, farmers grew strawberries based on experience. Now, they make money with Saifan's 'light formula'. This is the power of technology!" " Professor Zhang said with a smile. Nowadays, this "light control solution" has been promoted in over ten strawberry bases across the country, driving farmers to increase their income by an average of 150,000 yuan per year.
Let every user "use with peace of mind" : From devices to services, be the "light expert" by your side
Saifan Optoelectronics is well aware that good equipment requires good service support. In response to the mass production demands of the enterprise where Engineer Wang works, the Saifan team went on-site to set up an automated testing line. They connected 10 simulators with the MES system of the production line, achieving full-process automation from "testing - sorting - data upload". The testing efficiency was increased to 60 pieces per minute, and the A-grade product rate rose from 88% to 93%. Provide "aerospace-level operation training" for Sister Li's team, covering 10 core skills such as setting extreme environmental parameters and spectral calibration, to ensure that everyone can operate proficiently. Customize a "light environment simulation package" for Professor Zhang's laboratory, and develop crop growth data analysis software to automatically generate correlation reports between light and yield.
What's even more considerate is the "long-term guarantee" : Saifan has set up 7 major spare parts centers across the country, reserving 98% of commonly used spare parts, and promises to provide on-site repair within 48 hours for equipment failure. The lifespan of the LED light source is up to 10,000 hours. Calculated based on an 8-hour daily usage, the lamp does not need to be replaced for three years, saving 50,000 yuan in replacement costs annually compared to traditional xenon lamp simulators. The overall power consumption of the machine is only 650W, which is 70% more energy-efficient than the industry average. A photovoltaic production line with an annual output of 1GW can save 200,000 yuan in electricity fees each year. "Choosing Saifan is not just about buying a piece of equipment; it's more like having an additional 'optical technology partner', saving you both time and effort!" " This is the common evaluation of many users.
From the technological breakthroughs in the photovoltaic laboratory to the rigorous verification in the aerospace test room, and then to the joy of harvest in the fields, Saifan Optoelectronics' solar simulators have always stood in the user's perspective, using "precise, stable and customizable" light to help every striver break through the limitations of light. When "the light that understands you" meets "the adventurous you", more innovative miracles are quietly taking place.
