The precise performance calibration of micro-area photovoltaic devices, thin-film batteries, perovskite chips, and semiconductor photovoltaic chips requires extremely strict requirements for light accuracy, spectral purity, and long-term stability. Traditional pulsed simulators have limited flash duration, large light intensity fluctuations, and poor spectral tunability. They cannot support micro-area steady-state testing, long-term aging, and continuous MPPT tracking, becoming the core bottleneck in the research and development and iteration of new photovoltaic materials and micro-optoelectronic devices.
By delving into the field of precise photovoltaic light simulation, Saifan Optoelectronics relies on its self-developed multi-band LED spectral mixing, closed-loop light intensity feedback, and steady-state intelligent light control core technologies to launch the 7IS0502A 3A-level LED steady-state solar simulator. Strictly benchmarking against the latest international standard IEC 60904-9:2020, it achieves triple 3A top-level indicators of spectral matching, irradiation uniformity, and time stability. With its hard-core performance of cold light source without thermal interference, independent band adjustment, and millisecond-level steady-state locking light, it is specially designed to create a standardized daylight simulation solution for micro-area, small-size, and high-precision photovoltaic testing, laying a traceable and precise light baseline for laboratory cutting-edge research, new product process iteration, and precise device calibration.

The 7IS0502A, as a small-sized high-precision steady-state simulation benchmark device, breaks through the accuracy limit of conventional simulators in all dimensions, and all three core performances fully meet the 3A top standards. The spectral matching degree is strictly controlled within the 0.875–1.125 standard range, accurately replicating the full-band distribution of AM1.5G standard daylight, with extremely high spectral fidelity. It can precisely match the light response characteristics of various new thin-film photovoltaic devices such as perovskite, gallium arsenide, cadmium telluride, and micro-crystalline silicon, completely eliminating the problem of spectral offset-induced test data distortion and efficiency misjudgment.
