This part of IEC 60904 describes procedures for the measurement of the current-voltage (I-V) characteristics of bifacial photovoltaic devices in natural or simulated sunlight. It is applicable to single PV cells, sub-assemblies of such cells or entire PV modules.
The requirements for measurement of I-V characteristics of standard (monofacial) PV devices are covered by IEC 60904-1 , whereas this document describes the additional requirements for the measurement of I-V characteristics of bifacial PV devices.
