光伏器件.第7部分:光伏器件测量用光谱失配校正的计算

[中文适用范围]： 本部分IEC 60904描述了用于校正光伏器件测试中因测试光谱与参考光谱（例如AM1.5光谱）不匹配以及参考器件与测试器件的光谱响应度（SR）不匹配而引入的光谱不匹配误差的程序，从而降低系统不确定性。该程序适用于单结器件，但原理可扩展至多结器件。本文件的目的是为校正光谱不匹配误差提供指南，即当测试光谱与参考光谱之间存在光谱不匹配，且参考器件SR与测试器件SR之间存在光谱响应度不匹配时。计算出的光谱不匹配校正仅对使用特定测试光谱测量的特定测试和参考器件组合有效。 [外文原描述]： IEC 60904-7:2019 describes the procedure for correcting the spectral mismatch error introduced in the testing of a photovoltaic device, caused by the mismatch between the test spectrum and the reference spectrum (e.g. AM1.5 spectrum) and by the mismatch between the spectral responsivities (SR) of the reference device and of the device under test and therewith reduce the systematic uncertainty. This procedure is valid for single-junction devices but the principle may be extended to cover multi-junction devices. The purpose of this document is to give guidelines for the correction of the spectral mismatch error, should there be a spectral mismatch between the test spectrum and the reference spectrum as well as between the reference device SR and the device under test SR. The calculated spectral mismatch correction is only valid for the specific combination of test and reference devices measured with a particular test spectrum. This fourth edition cancels and replaces the third edition published in 2008. The main technical changes with respect to the previous edition are as follows: - For better compatibility and less redundancy, the clause “Determination of test spectrum” refers to IEC 60904-9. - The spectral mismatch factor is called SMM instead of MM to enable differentiation to the angular mismatch factor AMM and spectral angular mismatch factor SAMM. - Formulae for the derivation and application of the spectral mismatch factor SMM are added. - Links to new standards are given, e.g. concerning multi-junction devices. - Corrected wording (responsivity instead of response and irradiance instead of intensity).
