The "uncontrollability" of natural sunlight was once a "roadblock" for innovation in countless industries - photovoltaic research and development was repeatedly halted due to unpredictable weather conditions, aerospace testing was struggling because space light was difficult to replicate, and agricultural planting was restricted in terms of income due to insufficient seasonal sunlight... When "relying on the sky and borrowing light" becomes a development bottleneck, Saifan Optoelectronics, after 20 years of in-depth research and development, has created a solar simulator. As a "customizer of light", it leverages its core capabilities of "precise replication, stable output, and on-demand customization" to tailor exclusive lighting solutions for photovoltaic, aerospace, scientific research, and agriculture, ensuring that each field can enjoy "just right" sunlight. Completely break free from the constraints of natural light.
Photovoltaic R&D: Customizing "High-efficiency light" to Break Through Battery Efficiency "One Step ahead"
The perovskite solar cell R&D team of a certain photovoltaic enterprise was once tormented by "data fluctuations" : during outdoor tests, the conversion efficiency of the same batch of cells fluctuated repeatedly between 22.3% and 24.1%, with a deviation of more than 8% within a week, and the R&D direction could never be focused. The optimal parameters measured today will become invalid tomorrow due to changes in light, as if playing hide-and-seek with the sunlight. The team leader said helplessly. It was not until the Saifan solar simulator entered the market that the research and development truly "stepped on the gas".
As a "customizer of light", Saifan Simulator is best at "replicating ideal lighting" : It covers the full spectrum from 400nm to 1100nm. Through the 5th generation intelligent spectral fitting algorithm, it accurately reproduces the strong light on the surface of AM1.5G. Even the near-infrared "energy region" of 780-1100nm, which is often overlooked by traditional devices, can clearly reproduce every bit of energy fluctuation. The spectral matching degree reaches grade A + (0.875-1.125). More importantly, it can "lock the light" - with a light intensity fluctuation rate of ±0.3% per hour, which is equivalent to a continuous 12-hour test where the light intensity change does not exceed "the brightness of a night light". The ±2% spatial uniformity ensures that every part of the battery cell is exposed to the same light, and the data deviation is strictly controlled within 1%.
With this "customized optical device", the team discovered the core problem in just 8 days: the battery's absorption efficiency in the near-infrared band was 14% lower than expected. After targeted adjustment of the material formula, the battery conversion efficiency exceeded 28% at one stroke. The related results were published in "Solar RRL", and the time from the laboratory to pilot production was directly shortened by 50%. In the mass production stage, an automated test line composed of 10 Saifan simulators screens batteries at A speed of 60 cells per minute, increasing the A-grade product rate from 86% to 96%. This reduces the loss of defective products by over 20 million yuan annually, making the implementation speed of high-efficiency photovoltaic technology "lead the industry".
Aerospace Testing: Customized "Space Light" to "Escort" the Exploration Journey
When a certain team of China's space industry was testing the solar cell wings of a lunar spacecraft, they encountered a "fatal problem" : the light intensity on the lunar surface was only 14% of that on Earth, and the temperature difference between day and night exceeded 300℃. Traditional simulators either had inaccurate light intensity or could not withstand extreme temperatures. The test data was 15% lower than the actual lunar environment, making it impossible to assess the in-orbit lifespan of the cell wings. If the spacecraft runs out of power on the moon, the entire lunar exploration mission may fail. Ground tests must be 100% accurate. The chief engineer of the team said seriously. Saifan's "Space Light customized solution" has become the "key key" to breaking the deadlock.
Saifan, the "customizer of Light", is best at "replicating extreme space light" : In response to the demands of lunar exploration, it developed the "AM0 Spectrum + Low-temperature Enhancement" dedicated module in just five days, increasing the irradiance of the ultraviolet band by 25% and perfectly recreating the strong radiation and low light environment on the lunar surface. The equipment adopts a military-grade 6061-T6 aluminum alloy body and an airtight packaging design, like putting on an "aerospace-grade protective suit" for light. It operates stably under extreme temperatures ranging from -180 ℃ to 60℃, with light intensity fluctuations always ≤±1.5%. During the continuous 500-hour simulation test, the equipment accurately recorded the aging law of the battery wing material under extremely cold and strong radiation. The new protective coating selected has extended the in-orbit life of the battery wing by six times, building a solid "energy security defense line" for the lunar exploration mission.
In the Mars exploration mission, the Saifan team once again demonstrated their "customization capabilities" : they completed the development of the "AM0 + Mars Atmosphere Filtration" module within 7 days, restoring 43% of the light intensity and special spectrum on the Martian surface. The power generation efficiency of the optimized Mars rover's solar panels increased by 28%, completely solving the "energy anxiety" in deep space exploration.
Research and Agriculture: Customizing "Personalized Light" to Unlock the "Double Code" of Innovation and Income Increase
When Professor Li's team from Qingdao University was researching "photocatalytic degradation of microplastics", they were stuck for a year due to the "rigid spectrum" of traditional equipment. We need to gradually adjust the proportion of the ultraviolet band (from 3% to 25%) and the blue light intensity (from 0.3sun to 1.2sun), and observe the influence of different light qualities on the degradation efficiency. However, ordinary simulators can only output a fixed spectrum, like "machines that cannot adapt". The "Personalized light customization" function of the Saifan solar simulator has brought a "turning point" to the experiment.
This "customizer of light" can be called a "spectral magician" : the ultraviolet-visible and near-infrared bands can be adjusted with 1% precision, the light intensity can be freely switched from 0.1sun to 2sun, and it can also simulate the alternations of day and night, seasonal changes, and even output special modes such as pulsed light and gradient light. Professor Li's team, through "step-by-step debugging", ultimately discovered that when the proportion of ultraviolet rays was 20% and the blue light intensity was 0.8sun, the degradation efficiency of microplastics reached its peak, increasing by 50% compared to the initial scheme. The related results were published in Environmental Science & Technology. Provide a "brand-new technical path" for the control of microplastic pollution.
In the agricultural sector, Saifan, the "customizer of light", has transformed into a "production-increasing magic tool". Lao Wu, a blueberry grower in Zhejiang Province, once looked worried due to insufficient sunlight in winter: "The sweetness of blueberries in greenhouses is only 10Brix, the yield per mu is less than 1,600 kilograms, and the selling price per jin is less than 25 yuan. After deducting the costs, it's almost unprofitable." " According to the "light-loving characteristics" of blueberries, the technicians of Saifan have customized a lighting scheme of "60% red light + 15% blue light + 5% ultraviolet light", providing 7 hours of customized light every day. Four months later, the sweetness of Lao Wu's blueberries soared to 17Brix, the yield per mu exceeded 2,000 kilograms, the price per jin rose to 45 yuan, and the annual income of his 20 mu of land increased by more than 400,000 yuan. Nowadays, local farmers have followed suit one after another, and Saifan's "customized light" has truly become a "wealth light".
Full-cycle service: Be the "partner of light", making the customization journey "worry-free throughout"
Saifan Optoelectronics is well aware that "good customization" cannot be achieved without "good service". Eight regional spare parts centers across the country have over 98% of commonly used components in stock. The 7× 24-hour response mechanism ensures that equipment malfunctions can be repaired within 24 hours. For instance, a simulator on the production line of a certain photovoltaic enterprise suddenly malfunctioned. Engineers from Saifan arrived at the scene within one hour and completed the repair within 1.5 hours, without affecting the production of the day. In response to the special needs of research institutions, Saifan also offers "one-on-one customized training". After a laboratory of a certain university purchased equipment, engineers visited the site for five consecutive days, providing hands-on teaching from spectral calibration to data export. This enabled the team to independently complete the "light customization" experiment within a week.
Today, Saifan solar simulators have created exclusive lighting solutions for over 350 customers worldwide. The repurchase rate of core customers has reached 88%, and 92% of new customers come from referrals by existing customers. From the efficient operation of photovoltaic production lines to the safe execution of space missions, from scientific research breakthroughs in laboratories to the joy of harvest in farmlands, Saifan Optoelectronics has always been the "customizer of light", ensuring that every industry can enjoy the "just right" sunlight. If your field is also "trapped by light", Saifan is the partner that can "customize sunlight" for you.
