BS EN 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.The requirements for measurement of current-voltage characteristics of single-junction PV
devices are covered by IEC 60904-1 whereas this document describes the additional
requirements for the measurement of current-voltage characteristics of multi-junction PV
devices.This document may be applicable to PV devices designed for use under concentrated
irradiation if they are measured without the optics for concentration and irradiated using direct
normal irradiance and a mismatch correction with respect to a direct normal reference
spectral irradiance distribution is performed. The reference spectral irradiance distribution is
provided in IEC 60904-3.Cross References:IEC 60904-3:2016IEC 60904-2:2015 ED3IEC 60904-8:2014 ED3IEC 60891:2009IEC 60904-9:2007IEC 60904-8-1:2017IEC 60904-4:2009IEC TS 61836:2016IEC 60904-1:2006IEC 60904-7:2008All current amendments available at time of purchase are included with the purchase of this document.
