In the journey of photovoltaic technology from the laboratory to industrialization, light has always been the intangible ruler for measuring efficiency and reliability. However, the ever-changing and uncontrollable nature of natural light makes it difficult for researchers to capture the essential laws of light in repetitive experiments. The birth of the Saifan Optoelectronics 7IS0503A-LED 3A level steady-state solar simulator is designed to solve this problem - it takes "steady-state" as the core and "precision" as the gene, redefining the lighting benchmark for photovoltaic research.
1、 Reproduction of Light: A Full Dimensional Simulation from Spectrum to Energy
The 7IS0503A-LED is equipped with Saifan Optoelectronics' independently developed LED spectral fitting system, covering the wavelength range of 400nm to 1100nm, with a spectral matching degree of A+level (0.875-1.125), far exceeding the IEC 60904-9-2020 international standard. Its core advantages lie in:
Spectral adjustability: Through independent control technology of 6 spectral bands, it can accurately simulate AM1.5G standard spectra, solar spectra in different seasons/regions, and even customize exclusive spectral curves for new devices such as perovskite stack cells and quantum dot cells.
Spot uniformity: By using a combination of dual compound eye lenses and microprism array technology, spatial non-uniformity of<± 1% (Class A standard) is achieved within the range of a Φ 70mm spot, ensuring that the surface irradiance difference of the photovoltaic device is less than 1%, meeting high-precision requirements such as IV curve testing and MPPT stability testing.
Energy stability: Equipped with a built-in light intensity feedback system and high-precision constant current source, it achieves 1% step adjustment within the range of 100-1100W/m ², with long-term irradiation instability<0.7%, providing a stable light source for efficiency attenuation analysis and aging testing of photovoltaic devices.
2、 Eternity of Light: The Technological Revolution Behind a 100000 Hour Lifespan
Traditional xenon lamp simulators often need to replace the light source every 2000 hours due to issues such as filament loss and spectral drift. However, 7IS0503A-LED, with its inherent long lifespan characteristics and Saifan Optoelectronics' heat dissipation design, has increased the light source lifespan to 100000 hours, completely ending the "light source maintenance anxiety". Its technological breakthroughs are reflected in:
Intelligent temperature control algorithm: By using heat pipe heat dissipation and PID temperature control, the LED junction temperature fluctuation is controlled within ± 1 ℃, avoiding spectral drift and power attenuation caused by temperature.
Low voltage constant current drive: Using an independent constant current source to control each group of LED beads not only improves driving efficiency, but also eliminates the risk of leakage in traditional high-voltage drives, extending equipment maintenance cycles to more than 5 years.
Energy consumption revolution: The rated power of the whole machine is only 650W, which is 60% more energy-efficient than traditional xenon lamp simulators, helping research institutions and enterprises achieve the goal of "green laboratories".
3、 Empowerment of Light: Full Scene Coverage from Laboratory to Industrialization
The "steady-state" characteristics of 7IS0503A-LED make it a "universal light source" for all links in the photovoltaic industry chain:
R&D end: In the IV testing of perovskite solar cells, its 100mm × 100mm light spot can simultaneously irradiate 12 samples, combined with Saifan Optoelectronics' multi-channel digital source meter and nitrogen sealed temperature control fixture, achieving a 300% increase in efficiency testing efficiency.
Production end: In the mass production quality inspection of photovoltaic modules, its ± 2% time stability (A-level standard) can ensure that the power calibration error of each module is less than 0.5%, avoiding yield loss caused by light source fluctuations.
Academic side: Chongqing University, Nanjing University of Aeronautics and Astronautics and other universities have applied it to the stability research of perovskite stacked batteries. Its<1% long-term irradiation instability provides reliable data support for the study of efficiency degradation mechanism of new batteries.
