自然阳光辐照度测量技术和装置的研究

Research on Techniques and Devices of Nature Sunlight Irradiance Measurements

采用自然阳光作为校准太阳能电池/组件的光源,与采用太阳模拟器作为光源相比有一系列优点,符合国际标准规定/推荐的对高级别光辐射标准和参考太阳能电池/组件校准的要求。福建省计量科学研究院与中国科学院长春光学精密机械与物理研究所合作研究,采用了锥型光接收腔与参考腔的腔型绝对辐射计和双轴双模式的太阳跟踪仪,太阳直接辐照度测量结果不确定度=1.0%(=2),在光伏领域达到国内领先水平,为校准参考太阳能电池/组件奠定了基础。

There are some advantages to use nature sunlight as the source of solar cell calibration compared with the usage of solar simulator. It accords with the request for calibration of solar cell that recommended by international criterion. There is a cooperate research to do it between Fujian Metroiogy Institute and Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences,.It uses the solar irradiance absolute radiometer as the main baseline with the automatic solar tracker. The uncertainty of direct solar irradiance measurement is U=1.0%（k=2）, keeps ahead in the PV ifeld, it makes a foundation for calibration of reference solar cell.
