光伏器件.第3部分:带参考光谱辐照度数据的地面光伏（PV）太阳能器件的测量原理

[中文适用范围]： 本文档适用于以下用于陆地应用的光伏器件：带或不带保护盖的太阳能电池；太阳能电池组件；组件；系统。注：术语“测试样品”用于指代上述任何一种器件。本文档中包含的原理涵盖自然光和模拟光下的测试。由于光伏转换具有光谱选择性（源于光伏太阳能电池和模块中使用的半导体材料的性质），为了比较不同光伏器件和材料的相对性能，需要参考标准太阳光谱分布。本文档包含了这样的参考太阳光谱辐照度分布。本文档还描述了确定光伏器件电输出的基本测量原理。文中给出的原理旨在将光伏器件的性能评级与共同的参考陆地太阳光谱辐照度分布联系起来。本文档中给出的参考陆地太阳光谱辐照度分布用于根据IEC 60904-9中规定的光谱性能要求对太阳能模拟器进行分类。 [外文原描述]： IEC 60904-3:2019 describes basic measurement principles for determining the electrical output of PV devices. The principles given in this document are designed to relate the performance rating of PV devices to a common reference terrestrial solar spectral irradiance distribution. The reference terrestrial solar spectral irradiance distribution is given in this document in order to classify solar simulators according to the spectral performance requirements contained in IEC 60904-9. The principles contained in this standard cover testing in both natural and simulated sunlight. This new edition includes the following significant technical changes with respect to the previous edition: a) all spectral data were recalculated due to some minor calculation and rounding errors in the third edition; the global spectral irradiance returned to exactly the data of the second edition; b) the angular distribution of the irradiance was clarified.
