The "uncontrollability" of natural light was once a major obstacle to innovation in fields such as photovoltaic, aerospace, scientific research, and agriculture - photovoltaic research and development was halted due to rain, aerospace tests were difficult to replicate the space spectrum, and agricultural planting relied on the weather for harvest. Having been deeply engaged in the optoelectronics field for two decades, Saifan Optoelectronics has brought "controllable light" to various industries with a "precise, stable and customizable" solar simulator, making innovation no longer dependent on the weather.
Photovoltaic R&D: Precise light efficiency, accelerating efficiency breakthroughs
It has been overcast for a consecutive week, with the test data of perovskite solar cells fluctuating by more than 5%. The research and development progress in half a year has only been completed by 30%. The troubles of the R&D director of a certain photovoltaic enterprise reveal the common problems in the industry. The emergence of the Saifan solar simulator has completely reversed this situation.
This device covers the full spectrum from 350nm to 1100nm. Under the IEC 60904-9 standard, its spectral matching degree reaches A + level. It accurately reproduces the AM1.5G solar spectrum and can even capture the subtle absorption differences in the near-infrared band from 780 to 1100nm. More importantly, its continuous 8-hour light intensity fluctuation rate is as low as 0.08%, far exceeding the industry average of 0.3%, ensuring that the experimental data has "zero deviation".
With the help of the intelligent testing system built into the device, the R&D team was able to complete the material comparison test that originally took three days in one day, quickly identifying the battery's shortcoming in near-infrared absorption. Ultimately, the conversion efficiency of perovskite solar cells increased from 23% to 27.5%, the research and development cycle was shortened by 60%, and the related achievements were rapidly advanced to the pilot production stage. In the mass production stage, an automated test line composed of 10 Saifan simulators screens batteries at A speed of 60 pieces per minute. The A-grade product rate has increased from 88% to 93%, reducing defective product losses by over 12 million yuan annually.
Aerospace testing: Extreme adaptation, Building a solid safety defense line
A 1% deviation in light intensity during spacecraft battery wing testing could lead to a three-year error in in-orbit life assessment. The concerns of the aerospace testers were all resolved in the face of the Saifan simulator.
For the extreme environment of space, the Saifan simulator adopts a military-grade 6061-T6 aluminum alloy body and is equipped with a dual-circulation water-cooled temperature control system. It can operate stably within the range of -40 ℃ to 60℃, with temperature fluctuations controlled within ±0.3℃. When simulating the AM0 spectrum in space, through calibration of 200,000 sets of space spectral data, atmospheric interference is precisely removed, and the irradiance error is ≤±1%.
During the 720-hour aging test of the space station's battery wing, the fluctuation of the equipment's light intensity was always ≤0.1%, fully recording the aging law of the material and facilitating the development of a new type of anti-radiation coating, which extended the in-orbit service life of the battery wing from 5 years to 15 years. During the Mars exploration mission, the Saifan team customized an "infrared enhancement module" for seven days, increasing the irradiance in the 800-1100nm band by 30% and enhancing the power generation efficiency of the Mars rover's solar panels by 22%.
Scientific Research Agriculture: Customized Spectra, Unlocking Innovative income Growth
To study the impact of light quality on the sweetness of strawberries, traditional fill lights only have a fixed spectrum. The predicament of agricultural researchers has been broken by the "customization capability" of the Saifan Simulator.
This device supports 1% precision adjustment in the ultraviolet, visible and near-infrared bands. The light intensity can be freely switched from 0.1sun to 2sun, and it can also simulate day-night alternations, pulsed light and other modes. Through experiments, the team has developed the optimal light formula for strawberries, which is "65% red light + 10% blue light +2 hours of 380nm ultraviolet light". This formula has increased the sweetness of strawberries from 8 degrees to 11 degrees, raised the anthocyanin content by 18%, and increased the annual income of 20 mu of greenhouses by over 200,000 yuan. This plan has been promoted in more than 10 bases across the country.
In the field of photocatalysis, a certain university has increased the efficiency of CO₂ reduction to methanol by 60% by leveraging its "ultraviolet + near-infrared synergistic illumination" model, and over 20 of its achievements have been published in SCI journals.
Full-cycle service, worry-free and effortless
Saifan Optoelectronics not only offers high-quality equipment but also builds a full-cycle service system: seven major spare parts centers across the country reserve 98% of commonly used components and promise to provide on-site fault repair within 48 hours. The LED light source has a lifespan of up to 10,000 hours and does not need to be replaced for three years, saving 50,000 yuan in replacement costs annually compared to traditional equipment. The overall power consumption of the machine is 650W, saving 70% of energy. A 1GW photovoltaic production line can save 200,000 yuan in electricity fees annually.
From the efficient operation of photovoltaic production lines to the safe execution of space missions, and then to the joy of harvest in the fields, Saifan Optoelectronics' solar simulators have always broken the shackles of light for various industries with "controllable light". If your innovation is also troubled by the problem of light exposure, this "light that understands your needs" from Saifan is the key for you to break through the bottleneck.
