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]： 本部分IEC 60904适用于以下地面应用的光伏设备： - 带或不带保护盖的太阳能电池； - 太阳能电池的子组件； - 模块；和 - 系统。 注：术语“测试样品”用于表示这些设备中的任何一种。 本文件包含的原则涵盖了自然和模拟阳光下的测试。 光伏转换由于PV太阳能电池和模块中使用的半导体材料的性质而具有光谱选择性。为了比较不同PV设备和材料的相对性能，需要一个参考标准太阳光谱分布。本文件包括这样的参考太阳光谱辐照度分布。 本文件还描述了确定PV设备电输出的基本测量原理。本文件中给出的原理旨在将PV设备的性能评级与共同的参考地面太阳光谱辐照度分布联系起来。 本文件中给出的参考地面太阳光谱辐照度分布是为了根据IEC 60904-9中包含的光谱性能要求对太阳模拟器进行分类。 [外文原描述]： IEC 60904-3:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. 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.
