In the photovoltaic laboratory, engineers often put their experiments on hold due to rainy and cloudy days. In the space test room, researchers repeatedly debugged to reproduce space light. In agricultural greenhouses, growers are worried about insufficient seasonal light - the "uncontrollability" of natural light is like an invisible boundary, hindering the innovative steps of countless industries. After two decades of deep cultivation in the optoelectronics field, Saifan Optoelectronics has developed a solar simulator. With its core capabilities of "precise replication, stable output, and flexible customization", it has transformed into an "enabler of light", providing tailor-made controllable lighting solutions for photovoltaic, aerospace, scientific research, agriculture and other fields. This enables every industry to break through natural limitations and forge ahead at full speed on the path of innovation.
Photovoltaic R&D: With "Precise Light", Break through efficiency and "Avoid Detours"
The efficiency of the perovskite battery measured last week was 23.6%, but it dropped to 21.9% during this week's test on a cloudy day. The data fluctuates wildly, making it impossible to determine the direction for optimization. The R&D director of a certain photovoltaic enterprise once said helplessly. The capricious nature of natural light has led the team to repeatedly encounter obstacles in breaking through battery efficiency, spending half a year on "verifying the validity of data". It was not until the arrival of the Saifan solar simulator that the research and development truly "saw the light".
This "enabler of light" from Saifan best understands the "precise demands" of photovoltaic research and development: With full-spectrum coverage from 400nm to 1100nm, through the 5th generation intelligent spectral fitting algorithm, it can not only perfectly reproduce the strong light on the surface of AM1.5G, but also accurately restore every bit of energy fluctuation in the near-infrared "energy blind zone" of 780-1100nm, which is often overlooked by traditional devices. 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 "faint brightness of a mobile phone flash". The ±2% spatial uniformity ensures that every part of the battery cell is evenly "bathed" in light, with data deviation strictly controlled within 1%.
With this "stabilizing anchor", the team identified the core issue in just 10 days: the battery's absorption efficiency in the near-infrared band was 13% lower than expected. After targeted adjustment of the material formula, the battery conversion efficiency exceeded 28.3% at one stroke. The related results were published in ACS Energy Letters, and the cycle from the laboratory to pilot production was directly shortened by 60%. In the mass production stage, an automated test line composed of 8 Saifan simulators efficiently screens at A speed of 60 cells per minute, increasing the A-grade product rate of polycrystalline silicon cells from 85% to 95%. This reduces the loss of defective products by over 22 million yuan annually, making the implementation speed of high-efficiency photovoltaic technology "lead the industry".
Aerospace Testing: "Extreme Light" Builds a "Solid Safety Barrier" for Exploration Journeys
"When a spacecraft is out of power in space, it's like a 'lifeline has been cut off'. Ground tests must fully restore the space light, leaving no room for the slightest carelessness." " When testing the solar cell wings of a lunar exploration spacecraft, the chief engineer of a certain team in China's aerospace industry was deeply worried about the "incompetence" of traditional simulators. The light intensity on the lunar surface is only 14% of that on Earth, and the temperature difference between day and night exceeds 300℃. Traditional equipment either has inaccurate light intensity or cannot withstand extreme low temperatures. The test data deviates from the actual situation by more than 15%, making it impossible to assess the in-orbit lifespan of the battery wing at all. Saifan's "Space Light customized solution" has become the "key key" to breaking the deadlock.
Saifan, the "empowerer of light", is well aware of the "extreme demands" of aerospace testing: for lunar exploration missions, it developed a dedicated module of "AM0 spectrum + low-temperature Enhancement" in just five days, increasing the irradiance of the ultraviolet band by 25% and perfectly reproducing the special environment of strong radiation and low light 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. Even in extreme temperatures ranging from -180 ℃ to 60℃, the light intensity fluctuation can still be stably maintained within ±1.5%. During the continuous 500-hour simulation test, the equipment accurately recorded the aging curves of the battery wing material under extreme cold and strong radiation, helping the team screen out the new protective coating, which extended the in-orbit life of the battery wing by six times and built a "solid energy security barrier" for the lunar exploration mission.
In the Mars exploration mission, the Saifan team once again demonstrated its "customized hard power" : The "AM0 + Mars Atmosphere Filtration" module was developed within 7 days, accurately 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 has increased by 28%, completely solving the "energy anxiety" in deep space exploration and making the Mars rover "full of power" on distant planets.
Scientific research and Agriculture: Unlocking the Dual value of "Innovation + Income Increase" with "Customized Light"
"We are researching the photocatalytic degradation of microplastics and need to precisely adjust the proportion of the ultraviolet band from 3% to 25% and the blue light intensity from 0.3sun to 1.2sun. However, traditional simulators can only output a fixed spectrum, like being 'single-minded', and the experiment has been stuck for a year without any progress." " Professor Li's team from Qingdao University once fell into a research predicament due to the "inflexible" equipment. It was not until the "Personalized Light Customization" function of the Saifan solar simulator was launched that the experiment finally saw a glimmer of hope.
This "enabler of light" can be regarded as a "spectral magician" in the field of scientific research: the ultraviole-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. It provides a "brand-new technical path" for the control of microplastic pollution.
In the agricultural sector, Saifan, the "enabler of light", has transformed into a "magic tool for increasing income". 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 tailored a lighting plan of "60% red light + 15% blue light + 5% ultraviolet light", providing blueberries with 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 greenhouses all have signs that read "Saifan Customized Light, Sweet and Fragrant Blueberries", and the once "melancholy fields" have turned into "prosperous fields".
Full-cycle service: Be the "partner of light", making cooperation "worry-free and reassuring"
Saifan Optoelectronics is well aware that high-quality equipment requires considerate service support. 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 failures 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 served 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 an "enabler of light", helping various industries break through the boundaries of growth. If your innovation is also stuck by the "lighting problem", Saifan is the partner that can "light up hope" for you.
