When it comes to "sunshine", what people think of is the warmth and light bestowed by nature. However, in photovoltaic laboratories, aerospace test rooms and agricultural research greenhouses, a beam of "controllable, precise and stable" "artificial sunlight" has become the key to breaking through technological bottlenecks and promoting industrial upgrading. For two decades, Saifan Optoelectronics has been deeply engaged in the optoelectronics field. The solar simulator it has developed with cutting-edge technology is like a "magician of light", bringing the characteristics of natural sunlight into laboratories and production lines, and lighting up the path of innovation for various industries.
It is the "master of light color mixing", seamlessly integrating experimental data with nature
When conducting photovoltaic cell tests, the most feared thing is that "the simulated light is different from the real sunlight" - just like painting with the wrong paint, even the most exquisite work will deviate from the original meaning. The Saifan simulator can precisely replicate "every ray of color" of the sun: the combination of "xenon lamp main light source + LED supplementary light" is like having a complete set of top-grade pigments, covering the full spectrum from 400nm to 1100nm, from the "pale purple glow" of ultraviolet to the "warm red energy" of infrared, without missing a single one.
Even more remarkable is its "5th Generation Intelligent spectral Fitting Algorithm", which has been "refined" by 100,000 sets of natural spectral data, just like equipping a paintbrush with "precise navigation". Want to simulate the AM1.5G spectrum on the earth's surface at noon? It can restore the "intense yet uniform" texture of sunlight, making the deviation between the test data of perovskite solar cells and outdoor actual measurements almost zero. To replicate the AM0 spectrum in space? It can eliminate the influence of atmospheric "filtering", present the "pure energy" of the sun in the universe, and provide a "space-grade" light environment for the testing of solar cell wings on spacecraft. A certain photovoltaic enterprise discovered the absorption shortcoming in the near-infrared band with it, and increased the battery conversion efficiency from 24% to 27.5% at one stroke. The related achievements were also published in ACS Energy Letters.
It is a "constant-temperature precision kitchen", ensuring that the light is always "impartial".
Scientific research and production are like "boiling a pot of precise soup". When the light intensity fluctuates, the data will "boil over". The Saifan simulator, however, is like a kitchen with a constant temperature and fire. No matter how long it is "endured", the "heat" remains as stable as a rock.
Its combination of "0.1ms-level sensor + FPGA high-speed chip" is a double insurance of "real-time monitoring + second-level adjustment" for light. Even if there is only the slightest fluctuation in light intensity, the sensor, like a "sensitive thermometer", captures it instantly, and the chip, like an "experienced chef", adjusts it immediately, keeping the fluctuation within ±0.3% per hour - equivalent to making soup continuously for 8 hours, with the deviation of the fire size not exceeding the heat of "one match". Even in an "extremely cold environment" of -40 ℃ (simulating the low temperature in space) or a "high-temperature workshop" of 60℃, its military-grade aluminum alloy body and sealed design are like putting on a "constant-temperature protective suit" for the equipment, and the uniformity of light is always better than ±2%. The China Academy of Space Technology used it to test the solar cell wings of the space station. It operated continuously for 720 hours, and the data was so stable that the researchers exclaimed, "You can rest assured."
It is a "durable and energy-efficient home appliance", offering long-term peace of mind with a one-time investment
When buying equipment, the most feared thing is "frequent repairs every now and then and the electricity bill is terrifying". However, the Saifan simulator is like those old household appliances that "last for ten years without breaking down and consume less power", engraving "saving money and worry" into its DNA.
Its LED light source has a lifespan of up to 100,000 hours - if used for 8 hours a day, it can be used continuously for 34 years! Compared with the traditional xenon lamp's lifespan of "retiring after 20,000 hours", it is equivalent to replacing the lamp four times less. This not only avoids frequent shutdowns that delay experiments and production but also saves a large amount of money on consumables. Moreover, it has a "small appetite" : the entire machine consumes only 650W of power, which is about the same as a microwave oven at home and saves 70% more electricity than traditional xenon lamp equipment. A strawberry cooperative in Shandong Province has used it to regulate light. Not only has the sweetness of strawberries increased by 2 degrees and the yield per mu increased by 150 kilograms, but the annual electricity cost has also been saved by nearly 10,000 yuan compared to using traditional equipment. It truly achieves "both increased production and cost savings".
It is a "companion in a spacesuit", capable of "shining steadily" wherever it is.
Some equipment works fine in the laboratory but stops working in complex environments. However, the Saifan simulator is like "wearing a spacesuit", shining steadily no matter in the aerospace test room, photovoltaic production line, or agricultural greenhouse.
Its "military-grade 6061-T6 aluminum alloy body" and "airtight encapsulation of optical chamber + transmission chamber" serve as the "hard skeleton" and "protective shield" of the equipment: the former can withstand the "pulling" of sudden temperature changes, while the latter can prevent the "invasion" of dust and moisture. In the Mars exploration mission, the Saifan team customized the "AM0 + Infrared Enhancement" module in just 7 days, perfectly simulating the surface light of Mars. The optimized solar panels of the Mars rover have a 22% increase in power generation efficiency, providing a stable energy guarantee for the exploration mission.
What's more considerate is that Saifan also offers "full-cycle companionship" : 7 spare parts centers across the country, 7× 24-hour response, and equipment failure repair within 48 hours. We regularly hold technical training courses and have cultivated over 300 professional talents. The test fixtures customized for aerospace customers have also obtained national patents. Now, over 200 customers worldwide are using water, with a core repurchase rate of 82%. 85% of new customers are referred by existing ones - this trust is the best recognition for it.
From the efficiency breakthroughs of photovoltaic cells to the safe flight of spacecraft, from new scientific discoveries in laboratories to the joy of harvest in farmlands, Saifan Optoelectronics' solar simulators use beams of "precise, stable and worry-free" "artificial sunlight" to help solve problems and create value for all industries. If you are also looking for reliable, cost-effective and highly effective light testing equipment, Saifan Optoelectronics is worth a try.
