The authoritative certification and mass production calibration of large-sized photovoltaic modules, entire large-panel batteries, wide-breadth thin-film photovoltaics, and large-area photoelectric functional materials have extremely strict standards regarding the coverage of light irradiation areas, uniformity of global irradiation, spectral fidelity across all bands, and industrial-grade long-term stable performance. Traditional small and medium-sized light spot simulators cannot cover large-panel samples, and multiple splicing tests have large errors and poor data repeatability. Conventional large-breadth equipment generally have defects such as spectral discontinuity, edge irradiation attenuation, long-term light intensity drift, and insufficient ultraviolet energy, which easily lead to deviation in component efficiency grading, discrepant aging experiment data, low pass rate for authoritative certification, and inability to meet the high-precision standardized testing requirements of photovoltaic enterprises for pilot research and development, production line batch quality inspection, and third-party authoritative certification, thereby restricting the industrialization improvement and upgrading of high-end photovoltaic devices.
Deeply engaged in the field of high-end photovoltaic light simulation and precise detection, Saifan Optoelectronics relies on its self-developed ultra-large-area compound eye uniform light optical technology, full-spectrum xenon lamp precise color matching algorithm, and dual-loop dynamic light intensity compensation architecture, and has launched the 7IS1603A 3A-level xenon lamp steady-state solar simulator. Strictly following the international authoritative standard IEC 60904-9:2020, it achieves triple 3A top-level indicators of spectral matching, irradiation uniformity, and time stability, and with a 160×160mm ultra-large uniform light spot, full-band non-destructive replication of natural sunlight, extreme uniformity across the entire area, and industrial-grade long-term stable performance, it creates a dedicated certification-level light simulation solution for large-sized photovoltaic samples, providing precise, compliant, and traceable core testing benchmarks for cutting-edge scientific research innovation, pilot process iteration, and industrial authoritative quality inspection.
