In the laboratory for photovoltaic cell research and development, researchers are exploring the key to efficiency breakthroughs with the help of a stable beam of "sunlight". In the test room of aerospace materials, engineers verify the reliability of components by simulating space light. In the experimental field of the agricultural greenhouse, planting experts rely on customized spectra to cultivate high-quality crops... This beam of "light" that changes the innovation process of various industries comes from the LED solar simulator of Saifan Optoelectronics. With its precise, stable and efficient features, it has become an irreplaceable "light testing tool" in the eyes of countless users.
Solve the pain points in scientific research and make data the confidence for innovation
The most feared thing on the road of scientific research is the "drift" of data. A photovoltaic research team from a certain university was once deeply troubled by this. When testing the new perovskite solar cell, the unstable spectrum of the traditional simulator led to a data deviation of more than 2% under the same experimental conditions, and no reliable conclusion was reached within half a year. After switching to the LED solar simulator from Saifan Optoelectronics, the situation changed completely. The fifth-generation intelligent spectral fitting algorithm it is equipped with can accurately reproduce the AM1.5G standard spectrum, with a matching accuracy of ±0.5% and a light intensity fluctuation rate controlled within ±0.5% per hour. Taking advantage of this, the team quickly captured the special response of the battery in the 780nm band and achieved the research goal of breaking through 26% efficiency in just three months. The related results were successfully published in authoritative journals.
In the research of photocatalytic degradation of pollutants, the stability of the Saifan simulator is equally crucial. In a long-term experiment conducted by a certain environmental research institute, the equipment ran continuously for 1,000 hours, and the light intensity fluctuation never exceeded ±1%. This provided researchers with perfect linear data, clearly presenting the dynamic process of pollutant degradation and laying a solid foundation for breakthroughs in environmental protection technology.
Empower industrial upgrading and provide full-chain support from the laboratory to the production line
Photovoltaic industry: Accelerate the mass production and application of high-efficiency batteries
The research and development as well as mass production of high-efficiency photovoltaic cells cannot do without precise light testing equipment. A leading photovoltaic enterprise has introduced Saifan simulators as the core quality inspection equipment in the mass production of TOPCon cells. With A detection speed of 60 cells per minute and a testing accuracy of ±0.3%, the rate of A-grade battery cells has increased from 88% to 93%, reducing the loss of defective products by over ten million yuan annually. At the R&D end, the enterprise leveraged the precise near-infrared band regulation capability of the equipment to optimize the battery structure, increasing the conversion efficiency by 1.2 percentage points and generating a considerable annual profit increase of over 200 million yuan.
Aerospace field: Building a solid protective barrier for space exploration
Spacecraft have to withstand extreme light in space, and the performance of materials is directly related to the success or failure of the mission. When testing the outer protective materials of the space station, the China Academy of Space Technology selected the Saifan simulator to simulate the AM0 spectrum in space and the low-temperature environment of -40 ℃. After 1,000 hours of continuous testing, the equipment stably output a standard irradiance of 1367W/m², accurately capturing the performance degradation law of the material under strong radiation. The final selected new composite material has extended the service life by three times, providing a safety guarantee for the long-term operation of the space station.
Agricultural planting: Grow high-quality crops with spectral "formulas"
Light is the "invisible fertilizer" for crop growth. The "spectrum customization" capability of the Saifan simulator makes agricultural planting more scientific. A high-end flower base in Yunnan Province, in order to cultivate rare blue roses, uses Saifan equipment to adjust the ratio of blue light to red light, simulating the strong ultraviolet light environment on the plateau. After optimization, the anthocyanin content in rose petals has increased by 22%, the flowering period has been extended by 7 days, the market premium has reached 30%, and the annual income has increased by more than 5 million yuan. The strawberry planting cooperative in Shandong has adopted a customized spectral solution to increase the sweetness of strawberries by 2 degrees, boost the yield per mu by 150 kilograms, and advance the maturity period by 10 days, thus gaining an edge in the market competition.
Automotive industry: Ensuring the safety and reliability of intelligent travel
The sensor performance of smart cars is severely tested under complex lighting conditions. A certain new energy vehicle manufacturer has used Saifan Simulator to build an "extreme light scene library", simulating 20 scenarios such as tunnel glare and heavy rain backlighting. Tests found that a certain camera had a response delay of 50 milliseconds when there was a sudden change in strong light. After optimization, it was shortened to 10 milliseconds, ensuring that the autonomous driving system could make decisions in a timely manner. In the testing of on-board photovoltaic glass, the equipment simulates the light characteristics of different regions, helping enterprises optimize the design of light transmittance, increasing the on-board power generation by 18% and enhancing the driving range of new energy vehicles.
Service and technology provide dual protection to build a competitive barrier in the market
Saifan Optoelectronics has become the top choice in various industries not only because of its outstanding equipment performance, but also because of its all-round service guarantee. The "7× 24-hour technical support + 2-hour emergency response + 48-hour on-site service" system it has established ensures that users have no worries. The inspection line of a certain auto parts enterprise suddenly broke down. Engineers from Saifan arrived at the scene in 2 hours and completed the repair in 4 hours, avoiding an average daily production halt loss of 500,000 yuan. The seven regional spare parts centers across the country have over 95% of the commonly used spare parts in stock, ensuring that equipment malfunctions are resolved quickly.
Technically, the advantages of Saifan are hard to replicate. The independently developed spectral fitting algorithm has obtained three national patents. Many attempts by peer enterprises to imitate it have failed due to insufficient accuracy. The equipment supports customization and modification of spot size, spectral band, etc. within 7 days, which is three times faster than the industry average cycle. The "highland ultraviolet + tropical visible light" composite demand proposed by the Yunnan flower base was completed by the Saifan team in just 10 days, helping the base achieve mass production of characteristic flowers.
Today, Saifan Optoelectronics' LED solar simulators have served over 200 customers worldwide and hold a leading market share in the photovoltaic, aerospace, agricultural and other fields. Among the TOP 10 domestic photovoltaic enterprises, 7 and 6 major aerospace research institutions have all purchased its equipment in bulk, and the repurchase rate of core customers is as high as 82%. This "light of precision" from Saifan is continuously illuminating the path of innovation in various industries and has become an important force driving technological breakthroughs and industrial upgrading.
