The high-precision performance calibration of large-area photovoltaic cells, complete components, thin-film photovoltaic devices, and wide-area photovoltaic materials has extremely strict requirements for the integrity of the light spectrum, the uniformity of large-area irradiation, and the stability of long-term operation conditions. Traditional small-spot simulators cannot cover the entire sample, and the error of multi-point stitching testing is large; ordinary xenon lamp equipment lacks the ultraviolet band in the spectrum, has severe light intensity drift, and insufficient uniformity. This极易 causes inaccurate efficiency grading of large-area batteries, discrepant aging experiment data, and distorted reliability verification of devices, making it difficult to meet the standardized testing requirements of photovoltaic pilot research and development, industrial batch quality inspection, and authoritative certification testing, and restricting the high-precision industrialization implementation of the photovoltaic industry.
Deeply specializing in high-end sunlight simulation and photovoltaic precision testing, Saifan Optoelectronics relies on its self-developed full-spectrum xenon lamp coloration technology, large-area uniform light optical architecture, and dual-loop light intensity steady-state compensation algorithm, and has launched the 7IS01003A 3A-level xenon lamp steady-state solar simulator. Strictly following the latest international standard IEC 60904-9:2020， it achieves full coverage of the triple 3A top-level indicators of spectral matching， irradiation uniformity， and time stability. With a 100×100mm ultra-large uniform light spot， full-band real sunlight replication， industrial-level ultra-long stability， and wide-spectrum sample adaptation， it creates a standardized lighting solution exclusive for large-area samples， providing high-precision， traceable sunlight simulation benchmarks for universities' cutting-edge research， enterprises' pilot iterations， and industrial mass quality control.
