Today, with the accelerated iteration of photovoltaic technology, every 0.1% increase in battery efficiency may rewrite the competitive landscape of the industry. And precise testing is precisely the key to breaking through the efficiency bottleneck. Youdaoplaceholder0 large-aperture 3A-level LED steady-state solar simulator , with innovative LED light sources and intelligent control technology, redefines the accuracy and efficiency of photovoltaic testing, providing a "true solar" level testing environment for laboratory research and development, production line quality inspection and power station operation and maintenance.
LED light source revolution: precise, stable, long-lasting
Traditional xenon lamp simulators have pain points such as spectral attenuation, time-consuming preheating, and thermal damage risks. In contrast, the LED steady-state light source , through semiconductor light-emitting technology, achieves convenient "ready-to-use" operation, with test efficiency increased by more than 50%. Its multi-band chip array design, through precise spectral fitting algorithm, simulates the full spectral range from 350nm to 1150nm, with spectral matching error controlled within ±5%, perfectly meeting the AM1.5G standard. The lifespan of LED light sources can reach tens of thousands of hours, with an extremely low light attenuation rate, significantly reducing maintenance costs and providing a "non-destructive health check" environment for cutting-edge materials such as perovskite and tandem cells.
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.
Large coverage design: breaking through size limitations, suitable for all scenarios
As the size of photovoltaic modules continues to increase, the irradiation area of traditional simulators has become an efficiency bottleneck. Our large-aperture design , through a modular LED matrix layout, supports customizable light spots ranging from 100mm×100mm to 600mm×600mm, easily handling laboratory sample verification, pilot line mass production testing, and power station component evaluation. Combined with a height-adjustable optical path system, the equipment can flexibly adjust the test height to ensure uniform light exposure for advanced technologies such as bifacial cells and heterojunction (HJT), providing a precise test platform for tandem cells and TOPCon cells.
