Abstract

A phosphor-converted light-emitting diode (LED) solar simulator is an illuminance device that produced irradiance intensity and spectral close to the sunlight. It is determined as spectral mismatch, non-uniformity of irradiance, and temporal instability. This paper has improved the LED solar simulator (LSS) system to have a spectral distribution consistent with the AM1.5G spectrum at 100%. It was developed as a new prototype to have the AAA class spectral characteristics, time instability, and inconsistency according to IEC 60904-9. The results showed that an optimal approach was to use phosphor-converted natural white LED (pc-nWLED), combining a monochromatic near-infrared (NIR) (730, 800, 850, 940, and 1,000 nm) as well as the proposed LSS system capable of generating 1,000 W/m2 irradiation over the test plane of 125×125 mm and operated continuously in a constant temperature LED state for at least 2 hours, therefore suitable for demonstration of solar cell features under standard test condition (STC) in the laboratory.

改进的荧光粉转换发光二极管太阳模拟器的光谱失配和性能

磷光体转换发光二极管（LED）太阳能模拟器是一种产生接近太阳光的辐照度和光谱的照明设备。它被确定为光谱失配、辐照度的不均匀性和时间不稳定性。本文对LED太阳模拟器（LSS）系统进行了改进，使其光谱分布在100%时与AM1.5G光谱一致。它是作为一个新的原型开发的，具有AAA级光谱特性、时间不稳定性和不一致性，符合IEC 60904-9。结果表明，最佳方法是使用磷光体转换的天然白色LED（pc-nWLED），结合单色近红外（NIR）（730800850940和1000nm）以及所提出的LSS系统，该系统能够在125×125mm的测试平面上产生1000W/m2的辐射，并在恒温LED状态下连续工作至少2小时，因此适合在实验室中在标准测试条件（STC）下演示太阳能电池特性。
