The precise performance calibration of large-area photovoltaic samples, conventional battery cells, photoelectric sensor components, and photocatalytic materials has strict standards regarding the integrity of the light spectrum, the coverage area of the light spot, and the consistency of long-term steady-state conditions. Traditional solar light simulators often have problems such as incomplete spectral coverage, small effective light spots, uneven large-area irradiation, and significant long-term light intensity drift, which can easily cause deviations in battery conversion efficiency calculations, poor repeatability of material aging experiment data, and distorted performance calibration of large-area samples. This makes them unable to meet the standardized testing requirements for routine scientific research experiments, pilot sample detection, and device reliability verification in the field of photovoltaics and photoelectric materials, thereby restricting the regular and precise R&D and quality inspection work in the field of photovoltaics and photoelectric materials.
Based on the deep research in the field of precise daylight simulation and photoelectric detection technology, Saifan Optoelectronics relies on its self-developed multi-band LED mixed light fitting, high-speed closed-loop light intensity compensation, and high-precision uniform light optical architecture to launch the 7IS0503A 3A-level LED steady-state solar simulator. It strictly follows the international authoritative standard IEC 60904-9:2020, achieving full coverage of the three 3A top-level indicators of spectral matching, irradiation uniformity, and time stability. With core performance such as large-sized uniform light spots, full-band spectral restoration, cold light source without thermal interference, and ultra-long-time steady-state output, it is suitable for standardized testing of all types of photovoltaic and photoelectric materials, providing a highly reliable and traceable standard daylight simulation solution for universities' research, pilot development, and industrial quality inspection.
