Title: Photovoltaic devices : classification of solar simulator characteristics Photovoltaic devices: measurement of current-voltage characteristics of bifacial photovoltaic (pv) devices
Scope: Describes procedures for the measurement of the current-voltage (I-V) characteristics of bifacial photovoltaic evices 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. 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 spectrum is performed.
