Photovoltaic engineers no longer need to adjust their experimental plans based on weather forecasts, aerospace testers no longer have to repeatedly try and make mistakes to replicate space spectra, and agricultural researchers bid farewell to the predicament of "figuring out light formulas based on experience". The "uncontrollable light" problem that once plagued multiple fields has now been transformed into an innovative opportunity for "precise control of light" in the face of the solar simulator from Saifan Optoelectronics. Having been deeply engaged in the optoelectronics industry for two decades, Saifan, with its core advantages of "precision, intelligence and long-term effectiveness", has made this "light that understands demand" a key force for various industries to break through development bottlenecks.
Photovoltaic R&D: Intelligent Testing + Ultra-stable Output, Efficiency Breakthrough "One Step Ahead"
"Previously, when testing perovskite solar cells, the morning data was 23.5%, but it dropped to 21.8% in the afternoon on a cloudy day. It took half a year to verify the validity of the data, and the research and development progress was seriously lagging behind." " The concern of Mr. Liu, the R&D director of a certain photovoltaic enterprise, is a common pain point in the industry. The arrival of the Saifan solar simulator has completely changed this situation.
This device not only covers the full spectrum from 350nm to 1100nm, but also achieves A + level spectral matching under the IEC 60904-9 standard. It can accurately capture an absorption difference of 0.5% in the near-infrared band from 780 to 1100nm. It is also equipped with an intelligent testing system - through touch screen operation, 12 standard spectral modes such as AM1.5G and AM0 can be preset, and it supports the automatic generation of 15 core parameter reports such as IV curves, conversion efficiency, and fill factors. The material comparison test that originally took 3 days can now be completed in 1 day. Its stability is even leading in the industry: the light intensity fluctuation rate for 8 consecutive hours is as low as 0.08%, far exceeding the industry average of 0.3%. "The data measured today will have a reproduction error of no more than 0.1% next week. There is no need to worry about inaccurate data anymore."
With the help of equipment, Liu's team quickly identified the problem of a 12% lower near-infrared absorption efficiency of the battery. After optimizing the material structure, the conversion efficiency of the perovskite battery jumped from 23% to 27.5%, and the research and development cycle was shortened by 60%. In the mass production stage, an automated testing line composed of 10 Saifan simulators is seamlessly integrated with the MES system of the production line, achieving full-process automation from "testing - sorting - data upload". The testing speed reaches 60 pieces per minute, and the A-grade product rate has increased from 88% to 93%, reducing defective product losses by over 12 million yuan annually. "With Saifan, we can finally focus all our energy on technological breakthroughs. This is the right pace for R&D!" " Engineer Liu sighed.
Aerospace testing: Extreme Adaptability + Rapid customization, building a solid defense line for space security
"In-orbit life assessment of spacecraft battery wings: A 1% deviation in light intensity could lead to a three-year error. Traditional simulators simply cannot withstand the extreme space environment, and the test data is not reliable." " Sister Li, a space tester, had her concerns resolved in front of the Saifan simulator.
For the extreme temperature environment in space ranging from -40 ℃ to 60℃, the Saifan simulator adopts a military-grade 6061-T6 aluminum alloy body and is equipped with a dual-circulation water-cooled temperature control system, which keeps the operating temperature fluctuation of the equipment within ±0.3℃. Even under extremely cold and hot conditions, the spectral output deviation is still ≤±0.5%. When simulating the AM0 spectrum in space (solar radiation without atmospheric filtering), through calibration of 200,000 sets of space spectral data, atmospheric interference is precisely removed, with an irradiance error of ≤±1%, achieving a "1:1 replication" of space lighting.
During the 720-hour aging test of the space station's battery wing, the equipment continuously and stably output light, with the light intensity fluctuation always ≤0.1%, and completely recorded the aging curve of the material under strong ultraviolet rays and extremely low temperatures. Based on these data, the team developed a new type of anti-radiation coating, which extended the in-orbit lifespan of the battery wing from 5 years to 15 years. What is even more commendable is Saifan's "rapid customization capability" : In the Mars exploration mission, it completed the development of the "infrared enhancement module" in just 7 days, increasing the irradiance in the 800-1100nm band by 30%, perfectly reproducing the surface light of Mars, and helping to increase the power generation efficiency of the Mars rover's sails by 22%. "With this' Space Light replication machine 'from Saifan, we have more confidence in the power safety of our space missions!" " Sister Li said.
Scientific research in agriculture: Precise Regulation + Scenario Simulation, Allowing "Light Formula" to Bear "Fruits of Prosperity"
To study the impact of light quality on the sweetness of strawberries, traditional supplementary lights only have a fixed spectrum, just like "blindingly shooting arrows". The experiment has been stuck for half a year without any progress. Professor Zhang, an agricultural researcher, was completely overcome by the "customization capability" of the Saifan simulator.
The device supports 1% precision adjustment in the ultraviolet (350-400nm), visible (400-760nm), and near-infrared (760-1100nm) bands. The light intensity can be freely switched from 0.1sun (overcast light) to 2sun (midday strong light), and it can also simulate 8 types of lighting scenarios such as day and night alternations, seasonal changes, and pulsed light. Professor Zhang's team, through over a thousand experiments, has finally discovered the "optimal light formula" for strawberries: 65% red light and 10% blue light, supplemented with 2 hours of 380nm ultraviolet light every day (promoting anthocyanin synthesis).
The strawberry greenhouses in Shandong that were renovated according to this plan have achieved immediate results: the sweetness of strawberries has risen from 8 degrees to 11 degrees, the anthocyanin content has increased by 18%, the yield per mu has risen from 2,000 kilograms to 2,150 kilograms, the selling price per jin has gone up from 8 yuan to 12 yuan, and the annual income of 20 mu of land has increased by more than 200,000 yuan. "Now farmers no longer have to rely on the weather for their livelihood. By following Sai Fan's 'light formula' to grow strawberries, they can earn an extra 10,000 yuan per mu!" " Professor Zhang said with a smile that this plan has been promoted in over ten strawberry bases across the country, driving nearly a hundred households to increase their income by an average of 150,000 yuan per year. In the field of photocatalysis, a certain university has successfully increased the efficiency of CO₂ reduction to methanol by 60% by means of the "pulsed light mode" of the equipment, and more than 20 achievements have been published in SCI journals.

Saifan Optoelectronics is well aware that good equipment requires good service support. In terms of hardware, the device adopts long-life LED light sources with a lifespan of up to 10,000 hours. Calculated based on an 8-hour daily usage, it does not need to be replaced for three years, saving 50,000 yuan in replacement costs annually compared to traditional xenon lamp simulators. The overall power consumption of the machine is only 650W, saving 70% of energy. A 1GW photovoltaic production line can save 200,000 yuan in electricity fees annually.
In terms of service, Saifan has established a "7× 24-hour response + 7 major spare parts centers across the country" service system. It has a sufficient reserve of 98% of commonly used spare parts and promises to provide on-site repair within 48 hours in case of equipment failure. For customers in different industries, we offer "one-on-one" operation training, covering everything from spectral calibration to data interpretation, to ensure that the team can quickly get started. The head of a certain new energy enterprise commented: "Choosing Saifan is not just about purchasing a piece of equipment; it's more like having an additional 'optical technology partner'. From R&D to mass production, the entire process is worry-free!" "
From technological breakthroughs in photovoltaic laboratories to the safe execution of space missions and the joy of harvest in the fields, Saifan Optoelectronics' solar simulators have always been centered on "intelligent controllable light", solving the "light anxiety" in various industries. When "precise control of light" becomes possible, more innovative miracles are constantly emerging under the illumination of this "light that understands needs".
