Photovoltaic devices - Measurement of current-voltage characteristics of bifacial photovoltaic (PV) devices1 Scope 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 609041, whereas this document describes the additional requirements for
