For photovoltaic engineers, the most helpless thing is that "experimental data follow the weather". For aerospace researchers, the most worrying thing is that "space light cannot be reproduced on the ground." For agricultural growers, the most regrettable thing is that "a good harvest depends on the face of the sun" - the "capriciousness" of natural light has once held back the pace of innovation in countless industries. After 20 years of in-depth development, Saifan Optoelectronics has created a solar simulator. With the posture of a "customizer of light", it relies on its hard-core capabilities of "precise replication, stable output, and on-demand customization" to tailor "ideal lighting" for each field, allowing innovation to bid farewell to the passive situation of "relying on the sky and borrowing light".
Photovoltaic R&D: Customizing "High-efficiency light" to Break through battery efficiency and "Avoid detours"
Last week, the efficiency of the perovskite battery was measured at 23.5%. This week, when measured again on a cloudy day, it dropped to only 21.8%. The data is simply incomparable, and the research and development direction is almost lost. The R&D director of a certain photovoltaic enterprise once made a helpless joke. The capricious nature of natural light has led the team to repeatedly run into obstacles in breaking through battery efficiency, spending half a year on "verifying the validity of data". It was not until the entry of the Saifan solar simulator that the research and development truly "entered the fast lane".
As a "customizer of light", Saifan Simulator 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 in 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 "customized optical device", 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 28.2% 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: Customizing "Space Light" to "Build a Solid Safety Net" for Exploration Journeys
When a spacecraft loses power in space, it's like a "lifeline" has broken. Ground tests must fully restore the space light, leaving no room for the slightest deviation. 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 "customizer of Light", is well-versed in 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 extremely cold and strong radiation conditions, helping the team select a new protective coating that extended the in-orbit lifespan of the battery wing by six times, thus building a "solid energy safety net" 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.
Research and Agriculture: Customize "Personalized Light" to unlock the dual surprises of "Innovation + Income Increase"
"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 "customizer 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's "Customizer 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 the customization journey "worry-free and reassuring"
Saifan Optoelectronics is well aware that "good customization" cannot be achieved without "good company". 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 certain university's laboratory 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, truly achieving "buy with confidence and use with ease".
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 a "customizer of light", customizing "ideal light" for every industry. If your innovation is also stuck by the "lighting problem", Saifan is the partner that can "light up hope" for you.
