In the journey of photovoltaic technology towards higher efficiency and lower cost, the precise simulation of every beam of light is crucial to the success or failure of technological breakthroughs. Youdaoplaceholder0 steady-state LED solar simulator , with the deep integration of innovative LED light source technology and intelligent control system, redefines the accuracy and efficiency of photovoltaic testing, becoming the "gold standard" for laboratory research and development, production line quality inspection and power station operation and maintenance.
LED light source revolution: Say goodbye to tradition, embrace precision
Traditional xenon lamp simulators have pain points such as spectral attenuation, time-consuming preheating, and thermal damage risks. In contrast, the steady-state LED solar simulator achieves convenient "ready-to-use" operation through semiconductor light-emitting technology, with test efficiency increased by more than 50%. Its LED light source adopts a multi-band chip array design. Through a precise spectral fitting algorithm, it simulates the full spectral range from 350nm to 1100nm, with a spectral matching error controlled within ±5%, perfectly meeting the AM1.5G standard. It provides a "non-destructive physical examination" environment for cutting-edge materials such as perovskite and tandem cells, avoiding the interference of thermal effects on battery performance.
steady-state light field: the cornerstone of data reliability
The dynamic changes of sunlight are the core challenge in photovoltaic testing. The steady-state LED solar simulator ensures that the light intensity and spectrum remain constant during long-term testing through constant current drive and intelligent temperature control technology. The light intensity fluctuation is controlled within ±0.5%, meeting the requirements for long-term stability assessment of batteries. Its closed-loop control system monitors the junction temperature, current and light output intensity of the LED in real time. Combined with an efficient heat dissipation design, the lifespan of the light source can reach tens of thousands of hours, with an extremely low light attenuation rate, significantly reducing maintenance costs and data uncertainty.
3A grade standard: fully matched with real sunlight
Strictly in accordance with the international standard IEC 60904-9, the equipment has reached grade A in the three dimensions of spectral matching degree, irradiation uniformity and irradiation stability.
Spectral matching degree grade A : covering the full spectrum from ultraviolet to near-infrared, highly consistent with the AM1.5G standard, with an error of less than ±5%, ensuring the accuracy of testing for emerging materials such as perovskite and organic photovoltaics.
Irradiation uniformity grade A : The irradiance deviation within the spot range is less than ±2%, supporting full-area testing of large-sized solar cells (such as 182mm, 210mm) or modules, avoiding performance misjudgment caused by edge effects.
Irradiation stability grade A : The light intensity fluctuation is controlled within ±0.5%, providing an ideal environment close to natural light for IV characteristic testing and EQE analysis, and the data reliability is elevated to a new level.
