In front of the ultraviolet photocatalytic reactor in the hydrogen energy laboratory, a beam of light precisely reproducing the AM1.5G spectrum is penetrating the quartz window - this is the Saifan Optoelectronics 7IS0503A-LED solar simulator providing an energy reference for the water splitting hydrogen production reaction. As the global energy structure accelerates its transition towards clean energy, the "standard light environment" created by this device is becoming a key measurement fulcrum for breakthroughs in new energy technologies.
1. Cross-energy type testing capability: Breaking through the light-electricity-hydrogen conversion chain
Saifan Simulator, with its multi-spectral collaborative technology, has established a full-chain energy testing system
Photovoltaic-energy storage linkage test: In BYD's photovoltaic energy storage laboratory, the equipment simulates the changes in day and night light to simultaneously test the power generation efficiency of photovoltaic panels and the charging and discharging characteristics of energy storage batteries, providing data support for optimizing the matching degree of the photovoltaic-energy storage integrated system and increasing the overall energy efficiency of the system by 8%.
Photocatalytic hydrogen production calibration: Utilizing deuterium lamp auxiliary light source technology, the irradiance stability in the ultraviolet band is controlled within ±1.2%, providing a benchmark for the testing of new catalysts at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences. The testing error of its hydrogen production rate is reduced by 60% compared to traditional equipment. The related achievements have been selected as one of the "Top Ten Scientific and Technological Advances in China in 2024".
Artificial photosynthesis simulation: Equipped with a CO₂ concentration linkage control module, it can monitor the carbon sequestration rate of Chlorella in real time under simulated sunlight, providing parameters for the design of photosynthetic bioreactors. Based on this, a certain new energy enterprise has increased the biodiesel conversion rate to 32%.
Ii. Extreme Parameter Coverage: Breaking through the boundaries of energy material testing
In response to the extreme performance testing requirements of new energy materials, the equipment has achieved three major breakthroughs:
Ultra-high irradiance output: The short-term irradiance can reach 2000W/m², simulating the strong light environment in the desert to test the tolerance of the hot spot effect of photovoltaic modules, providing material selection basis for the construction of photovoltaic power stations in the Middle East.
Wide temperature range adaptation design: Maintains spectral stability in an environment ranging from -40 ℃ to 120℃, helping CATL test the cycle life of photovoltaic direct supply batteries under extreme temperatures. The data supports its automotive-grade photovoltaic storage batteries to pass the IEC 62109 certification.
Innovation in pulse light mode: Developed a 10Hz-1kHz adjustable pulse light source to simulate the light fluctuations caused by cloud cover and test the anti-interference ability of photovoltaic inverters. Based on this, Huawei optimized the inverter, which increased the conversion efficiency by 3 percentage points in low light.
Iii. Joint Construction of Industry Standards: Consolidating the Foundation of Energy Measurement
Saifan Optoelectronics is deeply involved in the formulation of new energy testing standards
In collaboration with the National Institute of Metrology of China, a standard device for photocatalytic hydrogen production was established, setting the first domestic benchmark for photocatalytic activity evaluation and addressing the industry pain point where data from different laboratories are incomparable.
Led the formulation of the "Group Standard for Performance Testing of Photovoltaic-Hydrogen Energy Systems", which standardizes the integrated testing process of photovoltaic electrolyzers and fuel cells. This standard has been included in the procurement technical requirements of the National Energy Group.
In collaboration with the international standardization organization IEC/TC82, the stability test method for LED light sources has been incorporated into the revised IEC 60904-10 standard, promoting the internationalization of Chinese technical solutions.
Iv. Benchmark Cases: Witnessing the Leap in New Energy Technology
At a certain solar thermal power station in Xinjiang, the Saifan mobile simulator was used to calibrate the on-site efficiency of the molten salt heat absorber. By simulating the solar altitude Angle at different latitudes and optimizing the layout of the condenser array, the heat absorption efficiency was increased by 5%, and the annual power generation was increased by 1.2 million kilowatt-hours.
A certain hydrogen energy enterprise adopted Saifan equipment to establish a pilot line for photocatalytic hydrogen production. By precisely controlling the light parameters, the catalyst usage was reduced from 8g/L to 5g/L, lowering the production cost per ton of green hydrogen by 1,800 yuan and achieving commercial operation half a year ahead of schedule.
As the new energy sector moves from technological research and development to industrial application, the accuracy of testing equipment directly determines the speed of the commercialization process. As a "light measurement anchor point", Saifan LED solar simulators provide traceable test benchmarks for fields such as photovoltaic, hydrogen energy, and biomass energy, ensuring that every kilowatt-hour of clean electricity and every cubic meter of green hydrogen can stand up to scientific measurement tests.
