Natural sunlight is a gift of life, but it is also a "variable problem" for scientific research and production - photovoltaic laboratories have suspended experiments due to rainy days, aerospace teams have repeatedly tried and made mistakes to reproduce space light, and agricultural greenhouses have reduced production due to insufficient winter light... When these predicaments of "relying on the weather for a living" become pain points in the industry, Saifan Optoelectronics' solar simulator, with 20 years of accumulation in optoelectronic technology, provides a beam of "precise, stable and customizable" artificial sunlight to break through the deadlock in various fields and become a "light companion" on the road of innovation.
It uses "hardcore precision" to "insure" the experimental data
For Wang, a photovoltaic engineer, the most headache-inducing issue is that "a slight difference in data can lead to a huge deviation in research and development." Previously, his team tested perovskite solar cells. Due to fluctuations in the intensity of natural sunlight, the core data of the three sets deviated by more than 3% within a week, and the research and development progress was delayed by half a month. It was not until the introduction of the Saifan solar simulator that the situation was completely reversed.
This device is like a "precision caliper of light" : It covers the full spectrum from 400nm to 1100nm. Every band from ultraviolet to near-infrared can be precisely replicated through the 5th generation intelligent spectral fitting algorithm, with A spectral matching degree reaching A + level (0.875-1.125). Even the near-infrared details of 780-1100nm, which are often overlooked by traditional equipment, are clearly presented. What is more crucial is its stability - a light intensity fluctuation rate of ±0.3% per hour, which is equivalent to a continuous test for 8 hours, with the light intensity deviation not exceeding "the brightness of a candle". ±2% spatial uniformity ensures that every corner of the battery cell receives the same amount of light. With this precision, the team led by Engineer Wang quickly identified the shortcoming of the battery's near-infrared absorption. After optimization, the conversion efficiency jumped from 24% to 27.5%, and the related results were successfully published in ACS Energy Letters.
It builds a defense line for space exploration with "extreme adaptability".
The team of Li Jie, a space researcher, once stayed up all night testing the solar cell wings of the space station. The extreme cold of -40 ℃ and strong ultraviolet radiation in space are simply impossible for traditional simulators to simulate. Material aging leads to data distortion, which directly affects the safety of the mission. The arrival of the Saifan solar simulator was like a "reassuring pill" for the team.
It adopts military-grade 6061-T6 aluminum alloy body and is designed with airtight packaging for the optical chamber and transmission chamber. It can operate stably in extreme environments ranging from -40 ℃ to 60℃, just like putting on a "space protective suit" for the equipment. When simulating the AM0 spectrum in space, it precisely eliminates the atmospheric filtering effect and restores the pure radiation of the sun in the universe. During the 720-hour continuous low-temperature irradiation test, the light intensity fluctuation was always ≤±1.2%, completely recording the aging law of the battery wing material. The new protective material finally selected by the team has extended the lifespan of the spacecraft coating by three times, building a solid safety barrier for manned space missions. In the Mars exploration project, the Saifan team customized the "AM0 + Infrared Enhancement" module in just 7 days, perfectly reproducing the surface light of Mars. The power generation efficiency of the optimized Mars rover's solar panels increased by 22%, becoming the "energy guarantee" for deep space exploration.
It relies on "flexible customization" to open a window for scientific research and innovation.
When Professor Zhang, an agricultural researcher, was studying the influence of light quality on the sweetness of strawberries, his experiment was halted for half a year because he was unable to precisely control the specific wavelength of light. The "spectral customization" function of the Saifan solar simulator has brought a breakthrough to his research.
This device is like a "palette of light" : 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 light cycle of day and night alternation and seasonal changes. Professor Zhang's team found through comparative experiments that when the proportion of red light was increased to 65% and supplemented by 10% blue light, the sweetness of strawberries increased by 2 degrees and the anthocyanin content increased by 18%. Based on this "light formula", they guided the Shandong Strawberry Cooperative to build light-controlled greenhouses. The yield per mu of 20 mu of land increased by 150 kilograms, and the annual income increased by more than 160,000 yuan. For researchers in the field of photocatalysis, the pulsed light and gradient light modes it supports have unlocked a new research direction of "interaction between light and matter", and more than 20 scientific research achievements have been published in SCI journals with the help of it.
It uses "long-lasting and worry-free" to "reduce costs" for enterprises.
Chen, the person in charge of the enterprise, finally did the math: The lifespan of traditional xenon lamp simulators is only 20,000 hours, the annual cost of replacing lamps exceeds 50,000 yuan, and the electricity bill is even higher. The LED light source of the Saifan simulator has a lifespan of 100,000 hours. Calculated based on an 8-hour daily usage, it can be used continuously for 34 years, almost eliminating the cost of lamp replacement. With a power consumption of 650W for the entire machine, it saves 70% of energy compared to traditional equipment. A photovoltaic production line with an annual output of 1GW can save over 200,000 yuan in electricity fees in a year.
What's even more considerate is Saifan's "full-cycle service" : 7 spare parts centers across the country reserve over 95% of commonly used parts, respond 7×24 hours, and repair equipment failures within 48 hours. The regularly held "Optical Simulation Technology Training Course" has trained five professional operators for Mr. Chen's team. Not only did I buy a good piece of equipment, but I also gained a technical partner. General Manager Chen commented like this.
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' solar simulators have always delivered "controllable light" to every corner of innovation with the attitude of "understanding needs, having strength, and being considerate enough". When the uncertainty of natural light becomes a thing of the past and precision and stability become the norm, those dreams that were once bound by "light" will eventually shine with even more dazzling brilliance under the illumination of this artificial ray of sunlight.
