摘要
太阳模拟器是光伏和材料降解研究中的关键设备,能够为光浸泡与耐久度测试提供稳定可控的特征辐照度光谱。基于大功率、单晶窄带小发光面的LED光源采用超半球齐明透镜进行全孔径集光,设计曲面分布式光学结构,从而高效实现目标靶面上的光谱匹配及1个太阳常数(辐照度为100 mW/cm^(2))的辐照度。实验结果表明,本文所设计的太阳模拟器在1000 h的时间内的辐照度波动低于1.15%,靶面中心60 mm×60 mm的正方形区域内辐照度不均匀性为1.98%,80 mm×80 mm区域内辐照度不均匀性为4.99%,光斑的光谱匹配度达到A级。该系统结构紧凑,可扩展性强,可用于长期稳态测量。
Solar simulator is a key equipment in the research of photovoltaic and material degradation,which can provide stable and controllable characteristic irradiance spectrum for light immersion and durability testing.Based on the high-power single-crystal narrow-band small-emitting surface LED light source,a super-hemispherical homogeneous lens is used to collect light in full aperture,and the distributed optical structure of the curved surface is designed,so as to achieve efficient spectral matching on the target surface and irradiance of one solar constant(irradiance of 100 mW/cm^(2)).The experimental results show that the irradiance fluctuation of the solar simulator designed in this paper is less than 1.15%within 1000 h,the irradiance non-uniformity in the square area of 60 mm×60 mm in the center of the target surface is 1.98%,the irradiance non-uniformity in the 80 mm×80 mm region is 4.99%,and the spectral matching of light spot reaches class A.The system has compact structure and strong expansibility,and can be used for long-term steady-state measurement.
