Photovoltaic R&D personnel no longer need to disrupt their experimental plans due to rain, aerospace test engineers no longer have to repeatedly try and make mistakes to replicate space light, and agricultural technicians bid farewell to the helplessness of "relying on the weather for harvest". The problem of "uncontrollable light" that once plagued many fields has been transformed into an innovative opportunity for "precise control of light" in the face of the solar simulator of Saifan Optoelectronics. Having been deeply engaged in the optoelectronics industry for two decades, Saifan, with its four core advantages of "precision, stability, customization and energy conservation", has made this "light that understands demand" a key force for various industries to break through development bottlenecks.
Photovoltaic R&D: 0.3% stability + intelligent testing, efficiency breakthrough "One step ahead"
"Previously, when testing perovskite/silicon tandem cells, the morning data was 25.1%, but it dropped to 23.8% in the afternoon on a cloudy day. We spent half a year verifying the validity of the data, and the research and development progress was seriously lagging behind." " The concern of Mr. Wang, the R&D director of a certain photovoltaic enterprise, is a common pain point in the industry. The arrival of the Saifan solar simulator has completely changed this situation.
This device is not merely a "precision calibrator of light" : The spectrum covers the entire band from 400nm to 1100nm. The 5th generation intelligent spectral fitting algorithm enables the spectral matching degree to reach A + level (0.875-1.125). Even in the near-infrared region of 780-1100nm, which is often overlooked by traditional equipment, the energy distribution restoration accuracy exceeds 98%. It is also equipped with an intelligent testing system - with touch screen operation, 12 standard spectral modes such as AM1.5G and AM0 can be preset, and 15 core parameter reports such as IV curves and conversion efficiency can be automatically generated. The material comparison test that originally took 3 days can now be completed in 1 day. Its stability is even leading in the industry: the light intensity fluctuation is as low as ±0.3% per hour. After a continuous 10-hour test, the light intensity change does not exceed "the brightness of a night light". The spatial uniformity reaches ±2%, and every inch of the battery cell can be evenly "bathed" in light. The data deviation is strictly locked within 1%.
With the help of the equipment, Wang's team identified the core issue within 12 days: the battery's absorption efficiency in the near-infrared band was 13% lower. After optimizing the materials, the battery conversion efficiency jumped to 27.3%, and the results were published in ACS Energy Letters. In the mass production stage, an automated testing line composed of 8 Saifan simulators is seamlessly integrated with the MES system of the production line. The testing speed reaches 60 pieces per minute, and the A-grade product rate has increased from 88% to 94%, reducing the loss of defective products by over 16 million yuan annually. What is more worth mentioning is that the equipment uses LED light sources, with a total power consumption of only 650W, which is 70% more energy-efficient than traditional xenon lamp equipment. A 1GW photovoltaic production line can save 200,000 yuan in electricity costs annually. "This Saifan device enables us to break through technical bottlenecks quickly and economically. This is the right pace for research and development!" " Engineer Wang sighed.
Aerospace testing: -40℃ to 60℃ tolerance + 7-day customization, building a solid defense line for space safety
"In-orbit life assessment of spacecraft battery wings: A 1% deviation in light intensity could lead to a three-year error. Traditional simulators have a light intensity drift of over 4% at a low temperature of -40 ℃. The test data is hard to believe." " The concerns of Sister Li, a test engineer from a certain team of China Aerospace, were all resolved in front of the Saifan simulator.
For the extreme environment of space, the Saifan simulator adopts a military-grade 6061-T6 aluminum alloy body, and is equipped with an airtight encapsulation of the optical chamber and transmission chamber. It is like putting on a "space protective suit" for the equipment. The temperature fluctuation within the range of -40℃ to 60℃ is ≤±0.3℃, and the spectral output deviation is always ≤±0.5%. When simulating the AM0 spectrum in space (solar radiation without atmospheric filtering), through calibration of 200,000 sets of space spectral data, atmospheric interference is precisely removed, with an irradiance error of ≤±1%, achieving a "1:1 replication" of space lighting. The equipment is also equipped with a 0.1ms high-sensitivity sensor, which can correct the light intensity fluctuations in real time. After continuous 720-hour low-temperature irradiation test, the light intensity deviation is always ≤±1.2%, fully recording the aging law of the material.
Based on these data, the team developed a new type of anti-radiation coating, which extended the in-orbit life of the battery wing by three times. During the Mars exploration mission, the Saifan team demonstrated "ultra-fast customization ability" : they completed the development of the "AM0 + Infrared Enhancement" module in just 7 days, increasing the irradiance in the 800-1100nm band by 30%, perfectly regenerating the surface light of Mars, and helping to increase the power generation efficiency of the Mars rover's solar panels by 22%, solving the "energy anxiety" in deep space exploration. "With this' Space Light replication machine 'from Saifan, we have more confidence in the power safety of our space missions!" " Sister Li said.
Scientific research Agriculture: 1% precision regulation + Scene Simulation, Allowing "Light Formula" to bear "Fruits of Prosperity"
To study photocatalytic hydrogen production, it is necessary to adjust the proportion of the ultraviolet band from 5% to 15%. Traditional equipment only has a fixed spectrum, and the experiment has been stuck for half a year without any progress. The predicament of Teacher Zhou from Qingdao University of Science and Technology was completely broken by the "customization capability" of Saifan Simulator.
This device can be called a "palette of light" : The ultraviolet (350-400nm), visible (400-760nm), and near-infrared (760-1100nm) bands support 1% precision adjustment. The light intensity can be freely switched from 0.1sun (overcast light) to 2sun (midday strong light), and it can also simulate 8 lighting scenarios such as day and night alternations, seasonal changes, and pulsed light. Professor Zhou's team increased the efficiency of photocatalytic hydrogen production by 40% through precise control, and the results were published in "Applied Catalysis B: Environmental".
In the agricultural sector, it is even more of a "green production-increasing wonder". Lao Yang, a strawberry grower in Shandong Province, once suffered from insufficient winter sunlight. The sweetness of his strawberries was only 8 degrees, with an average yield of less than 2,000 kilograms per mu and a selling price of 6 yuan per jin. After the introduction of Saifan equipment, the technical team customized a solution of "65% red light + 10% blue light +2 hours of 380nm ultraviolet light", supplementing 6 hours of "customized light" every day. After one growing season, the sweetness of strawberries soared to 11 degrees, the anthocyanin content increased by 18%, the yield per mu rose to 2,150 kilograms, the price per jin rose to 12 yuan, and the annual income of 20 mu of land increased by more than 200,000 yuan. "Before, we relied on the weather for a living. Now, we make money from 'Saifan Light', and the equipment consumes less electricity. The monthly electricity bill is half that of traditional supplementary lights!" " Lao Yang said with a smile that this plan has been promoted in over ten strawberry bases across the country, driving nearly a hundred households to increase their income by an average of 150,000 yuan per year.
Full-cycle service: 48-hour on-site visit + free calibration, ensuring innovation is "worry-free
Saifan Optoelectronics is well aware that good equipment requires good service support. The seven major regional spare parts centers across the country have over 95% of the commonly used spare parts in stock, providing a 7× 24-hour response. Equipment malfunctions can be repaired within 48 hours. A photovoltaic enterprise's production line simulator suddenly broke down. Engineers from Saifan arrived at the scene within 2 hours and completed the repair within 3 hours, without affecting the production of the day. For research institutions, we offer "one-on-one" training. After a certain university's laboratory made the purchase, engineers provided on-site guidance for three consecutive days, helping the team master core operations such as spectral regulation and data calibration within a week. What's more considerate is that when purchasing the equipment, you can enjoy the first spectral calibration service for free. The LED light source has a lifespan of up to 10,000 hours. Assuming it is used for 8 hours a day, it does not need to be replaced for 3 years, saving 50,000 yuan in replacement costs compared to traditional equipment annually.
Today, Saifan solar simulators have served over 200 customers worldwide. The repurchase rate of core customers is 82%, and 85% of new customers come from referrals by existing customers. From the efficient and energy-saving operation of photovoltaic production lines to the safe execution of space missions, and then to the green harvests in the fields, Saifan has always been helping various industries break the shackles of light with "controllable light". If your innovation is also hindered by the problem of light exposure, this "light that understands your needs" might just be the "golden key" for you to break through the bottleneck.
