Sunlight is a gift from nature, yet it is hard to resist the "unpredictable weather" and "regional differences" - photovoltaic laboratories cannot wait for the ideal light, aerospace tests cannot reproduce space sunlight, and agricultural greenhouses cannot retain the seasonal light... When "natural light" fails to meet the precise demands of various industries, the solar simulator developed by Saifan Optoelectronics over the past two decades has transformed into a "customizer" of light. With its core capabilities of "precise replication, stable output, and on-demand customization", it tailors exclusive lighting solutions for photovoltaic, aerospace, scientific research, and agriculture, allowing innovation to no longer be confined by nature. Let every field have the "just right" amount of sunlight.
Photovoltaic R&D: Customizing "High-efficiency light" to provide a "Shortcut" for Battery efficiency breakthroughs
The perovskite solar cell R&D team of a certain photovoltaic enterprise once fell into a "data maze" : during outdoor tests, the conversion efficiency of the same batch of cells fluctuated repeatedly between 22.5% and 24%, and the data deviation exceeded 6% within a week. The R&D personnel looked at the report and exclaimed, "It's like guessing a riddle." The spectrum and intensity of natural sunlight are constantly changing. The optimal parameters measured today will become invalid tomorrow. The team leader said helplessly. It was not until the entry of the Saifan solar simulator that the research and development entered the "fast lane".
This "Customizer of Light" from Saifan is best at "replicating the ideal sunlight" It covers the full spectrum from 400nm to 1100nm. Through the 5th generation intelligent spectral fitting algorithm, it can accurately reproduce 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 restore every bit of energy fluctuation. The spectral matching degree reaches grade A + (0.875-1.125). More importantly, it can "lock onto sunlight" - with a light intensity fluctuation rate of ±0.3% per hour, which is equivalent to a continuous 10-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 a key 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 27.8% at one stroke. The related results were published in ACS Energy Letters, and the time from the laboratory to pilot production was shortened by 40%. In the mass production stage, an automated test line composed of 8 Saifan simulators screens batteries at A speed of 60 cells per minute, increasing the A-grade product rate from 88% to 95%. This has reduced the annual loss of defective products by over 17 million yuan, significantly accelerating the implementation speed of high-efficiency photovoltaic technology.
Aerospace Testing: Customizing "Space Light" to Build a "Safety Shield" for Exploration Journeys
When a certain team of China's space program was testing the solar panels of a Mars rover, they encountered a "fatal problem" : the light intensity on the surface of Mars was only 43% of that on Earth, and the infrared band accounted for a higher proportion. Traditional simulators either had inaccurate light intensity or large spectral deviations, and the test data differed by 12% from the actual light on Mars, making it impossible to assess the in-orbit power generation capacity of the panels. If a Mars rover runs out of power on a distant planet, the mission will be in a desperate situation. Ground tests must be 100% realistic. The chief engineer of the team said seriously. Saifan's "Space Light Customized Solution" has become the key to breaking the deadlock.
Saifan, the "customizer of Light", is best at "replicating extreme sunlight" : In response to the demands of Mars exploration, it developed the "AM0 Spectrum + Infrared Enhancement" dedicated module in just 7 days, increasing the irradiance in the 800-1100nm band by 30% and perfectly reproducing the light characteristics on the Martian surface. The equipment adopts military-grade 6061-T6 aluminum alloy body and airtight packaging design, like putting on a "spacesuit" for light. It operates stably in extreme environments ranging from -40 ℃ to 60℃, with light intensity fluctuations always ≤±1.2%. During the 300-hour continuous simulation test, the equipment accurately recorded the changes in the power generation efficiency of the solar panels under Martian light, helping the team optimize the solar panel plan, which increased the power generation efficiency by 25% and completely solved the energy anxiety of Mars exploration.
In the test of the solar cell wings on the space station, Saifan Simulator further customized the "low-temperature strong ultraviolet light" solution to simulate the extremely cold and strong radiation environment of -40 ℃ in space. The new protective coating selected has extended the lifespan of the cell wings by three times, building a solid "energy security defense line" for manned space missions.
Research and Agriculture: Customizing "Personalized Light" to Unlock the "New Code" for Innovation and Income Growth
When Professor Zhang's team from Qingdao University of Science and Technology was researching "photocatalytic hydrogen production", they were stuck for half a year due to the "rigid spectrum" of traditional equipment. We need to gradually adjust the proportion of the ultraviolet band (from 5% to 20%) and the intensity of near-infrared light (from 0.5sun to 1.5sun), and observe the influence of different light qualities on the hydrogen production efficiency. However, ordinary simulators can only output a fixed spectrum, like being "single-minked". 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. Through "segment-by-segment debugging", Professor Zhang's team finally discovered that when the proportion of ultraviolet light was 15% and the intensity of near-infrared light was 0.9sun, the hydrogen production efficiency reached its peak, increasing by 42% compared with the initial scheme. The related results were published in "Applied Catalysis B: "Environmental", opening up new paths for new energy research.
In the agricultural sector, Saifan's "Customizer of light" has transformed into "high-yield light fertilizer". Sister Chen, a strawberry grower in Yunnan, once looked worried due to insufficient winter sunlight: "The sweetness of strawberries in greenhouses is only 8 degrees, the yield per mu is less than 2,000 kilograms, and the price per jin is only 8 yuan. We can't make money." " According to the "light-loving characteristics" of strawberries, the technicians of Saifan have customized a lighting plan of "65% red light + 10% blue light + 5% ultraviolet light", providing 6 hours of customized light every day. Three months later, the sweetness of Sister Chen's strawberries soared to 11 degrees, the yield per mu exceeded 2,200 kilograms, the price per jin rose to 15 yuan, and the annual income of her 20 mu of land increased by more than 250,000 yuan. Nowadays, local greenhouses all have the slogan "Saifan Customized Light, Strawberries Sweet and Fragrant" pasted on them. The once "fields of melancholy" have turned into "fields of prosperity".
Full-cycle service: Be a "partner of light" and make the customization journey more worry-free
Saifan Optoelectronics is well aware that "good customization" requires "good service" as a foundation. The 8 regional spare parts centers across the country have over 98% of commonly used spare parts 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 1.5 hours and completed the repair within 2 hours, without affecting the production of the day. In response to the special needs of research institutions, Saifan also offers "customized training". After a laboratory of a certain university purchased equipment, engineers visited the site for four 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 300 customers worldwide. The repurchase rate of core customers has reached 86%, and 90% 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 played the role of a "customizer" of light, ensuring that every industry can enjoy the "just right" sunlight.
