I have been purchasing xenon lamp equipment for three years. I spent 200,000 yuan on lamp replacement and electricity bills, but the data is still inaccurate. If you want to customize a special spectrum, foreign manufacturers have to wait for three months, and the project just falls through... This is the "pitfall" experience that most enterprises encounter when purchasing optical testing equipment. The solar simulator developed by Saifan Optoelectronics after 20 years of in-depth research in the optoelectronics industry, with its three core advantages of "0.3% accuracy, 11-year maintenance-free operation, and 72-hour customization", helps the photovoltaic, aerospace, scientific research, and agricultural fields avoid equipment selection traps and keep the pace of innovation one step ahead.
I. Photovoltaic R&D: From "Data Tug-of-war" to "Breaking the bottleneck in 12 days", Efficiency triples
Wang, the R&D director of a perovskite battery enterprise, was once so worried about equipment problems that he couldn't sleep: "I used xenon lamps to measure the battery efficiency. It was 25.2% in the morning and 23.8% in the afternoon, with a deviation of over 6%. I spent half a year verifying the data." The monthly electricity bill for 8 devices is 20,000 yuan. Replacing the lights costs 48,000 yuan a year. The finance department asks me every day for a "cost reduction plan". It was not until the Safan solar simulator was installed that the research and development finally "stepped on the gas".
Saifan's "accuracy" conceals solid skills
The independently developed 5th generation intelligent spectral fitting algorithm, trained on 2 million sets of measured data, has achieved A + level matching accuracy across the entire wavelength range of 400nm to 1100nm, and the restoration accuracy in the near-infrared region of 780nm exceeds 98%. With touch screen operation, 12 standard spectra such as AM1.5G and AM0 can be preset. After clicking "Start Test", the system automatically generates an IV curve report, and the data deviation is strictly locked within ±0.3%. "For the same batch of batteries now, the data measured today will have a reproduction error of no more than 0.5% next week. There's no need to compete with the data anymore." "
The cost advantage is obvious to the naked eye
With the help of equipment, Wang's team discovered the core issue of "the battery's near-infrared absorption efficiency being 13% lower" in just 12 days. After optimizing the materials, the efficiency jumped to 27.3%, and the results were published in Nature Photonics. "Choose the right optical equipment and the R&D progress will be at least three years faster!" "
Ii. Aerospace Testing: From "Waiting for equipment" to "7-day Customization", Reliable Even in Extreme Environments
The test of spacecraft battery wings requires an extremely cold environment of -40 ℃. The light intensity drift of the xenon lamp equipment exceeds 5%, so the data cannot be used. The solar panels of the Mars rover need AM0 + infrared enhanced spectrum. It will take three months to customize them from abroad. The project will definitely be delayed. Engineer Li from the Beijing Institute of Aerospace Metrology's anxiety once almost caused his team to miss a mission node. The "all-scenario adaptability" of the Saifan solar simulator has become a "savior" for aerospace testing.
Extreme environments can stand the test
The 6061-T6 military-grade body with airtight packaging 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 light intensity deviation in the 720-hour low-temperature irradiation test is ≤±1.2%. The spectral curve is monitored in real time with professional software. Even the slightest fluctuations can be automatically corrected, perfectly reproducing the AM0 spectrum in space. In the test of the battery wing of a certain space station, with this precise data, the new coating developed by the team has extended the in-orbit lifespan of the battery wing from 5 years to 15 years.
The customization speed has broken the industry record
During the Mars exploration mission, the R&D team completed the design of the "Infrared Enhancement module" in 72 hours. By increasing the density of lamp beads in the 800-1100nm band, the irradiance of this band was raised by 30%. The installation and debugging only took 48 hours, which is 98% shorter than the three-month cycle abroad. "Previously, when waiting for equipment, one had to look at others' faces. Now, Saifan can handle it in just seven days. Space missions no longer have to be held back." "
Iii. Scientific Research Experiments: From "Seizing the low-temperature period" to "generating data at any time", the output of results is 50% faster
In the photocatalytic hydrogen production experiment, for every 1℃ increase in ambient temperature, the catalyst activity drops by 3%. The surface of the xenon lamp equipment exceeds 70℃, the experimental bench gets hot, and the data repeatability is poor. I wanted to adjust the proportion of ultraviolet rays, but the equipment could only be set at a fixed speed. The experiment was stuck for half a year. Professor Zhou's concern from Qingdao University of Science and Technology is a common pain point in the field of scientific research. The "flexibility and stability" of the Saifan solar simulator have finally enabled the laboratory to "operate smoothly".
Its control power is comparable to a "palette of light"
The touch screen operation can achieve 1% precision adjustment in the ultraviolet (300-400nm), visible and near-infrared bands. The light intensity can be continuously switched from 1W/m² to 1500W/m², and 8 scene modes such as "day and night alternation" and "pulsed light" can also be set. After Professor Zhou's team adjusted the proportion of ultraviolet light to 15%, the efficiency of photocatalytic hydrogen production directly increased by 40%, and the cost of green hydrogen dropped to 35 yuan per kilogram, reaching the commercialization threshold.
Low-heat design solves scientific research problems
Distributed heat dissipation combined with microchannel water cooling technology, the surface temperature during operation is only 38℃, and the fluctuation of the experimental environment is ≤±0.5℃. Students no longer need to rush the "low-temperature period" to conduct experiments. Previously, one set of reliable data was produced every month, but now three sets can be produced every week. The publication speed of research results has increased by 50%, and two papers have already been published in SCI. Professor Zhou mentioned that the agricultural research group used it to simulate the highland light, and the yield of the cultivated barley increased by 25%, which has been promoted in Qinghai.
Iv. Agricultural Planting: From "Relying on the weather for harvest" to "increasing income solely through formula", it saves electricity and effort
Lao Yang, a strawberry grower in Shandong, once sighed in front of the greenhouse, "In winter, the light is insufficient. The sweetness of strawberries is only 8 degrees. They are sold at 6 yuan per jin. I lose 100,000 yuan a year on 20 mu of land." The traditional fill light consumes a lot of electricity, with a surface temperature exceeding 60℃. If you get too close, it will burn strawberries; if you get too far, the light will be uneven. After installing the Saifan solar simulator in 2023, the Strawberry garden has completely transformed.
Customize the "light formula" for precise increased production
After on-site research by the Saifan technical team, a customized solution of "65% red light + 10% blue light +2 hours of 380nm ultraviolet light" was formulated: red light promotes sugar content, blue light enhances hardness, and ultraviolet light increases anthocyanins. The equipment can be hung 30 centimeters above strawberries. With a surface temperature of 38℃, it will not burn the crops, and the uniformity of light exposure reaches 95%. After one growing season, the sweetness of strawberries rose to 11 degrees, the yield per mu increased 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.
The energy-saving effect exceeded expectations
The monthly electricity cost for traditional supplementary lighting is 1,200 yuan, while that for Saifan equipment is only 360 yuan, saving 10,000 yuan in electricity annually. "Before, growing strawberries relied on the weather. Now, it's thanks to the light from Saifan. It's worry-free and profitable. More than ten farmers around have followed me to buy!" "
V. Full-cycle Service: From "purchasing equipment" to "lifetime management", zero worries during use
Saifan is well aware that choosing optical equipment is not merely about purchasing hardware, but also about choosing long-term service. Its "Light Enjoyment Service" system covers the entire life cycle:
Fast response: With 7 major spare parts centers across the country, we can respond within 2 hours and repair within 4 hours. For a certain photovoltaic factory's equipment failure, engineers arrived within 2 hours and production resumed within 3 hours.
Customization: Photovoltaic customers enjoy "production line linkage debugging", scientific research customers have "spectral training", and agricultural customers receive "field guidance".
Guaranteed: Core components come with A 3-year warranty. Free on-site maintenance is provided after 3 years of use. A certain laboratory equipment has been in use for 5 years, and the spectral matching degree still remains at A + level.
Today, Saifan solar simulators have served over 200 customers worldwide, with a photovoltaic repurchase rate of 90%. They have supported 12 national-level tasks in the aerospace field and promoted over 20 SCI achievements in scientific research. Choosing the right optical equipment can save photovoltaic research and development three years of detours, prevent space missions from being held back, enable scientific research achievements to be produced quickly, and increase the profits of agricultural planting.
