IEC 60904-1-1:20 17描述了在自然或模拟阳光下测量多结光伏器件的电流-电压特性的程序。它适用于单个PV电池、此类电池的子组件或整个PV模块。它主要用于非聚光器件，但部分也可适用于聚光多结PV器件。一个重要的先决条件是多结器件的光谱响应度，其测量由IEC 60904-8-1涵盖。

IEC 60904-1-1:2017 describes procedures for the measurement of the current-voltage characteristics of multi-junction photovoltaic devices in natural or simulated sunlight. It is applicable to single PV cells, sub-assemblies of such cells or entire PV modules. It is principally intended for non-concentrating devices, but parts may be applicable also to concentrating multi-junction PV devices. An essential prerequisite is the spectral responsivity of the multi-junction devices, whose measurement is covered by IEC 60904-8-1.
