DANSK DSF/PREN IEC 60904-1 PDF

This part of IEC 60904 describes procedures for the measurement of current-voltage characteristics (I-V curves) of photovoltaic (PV) devices in natural or simulated sunlight. These procedures are applicable to a single photovoltaic solar cell, a sub-assembly of photovoltaic solar cells, or a PV module. They are applicable to single-junction mono-facial PV devices. For other device types it is required to refer to the respective documents, in particular for multi-junction devices to IEC 60904-1-1 and for bifacial devices to IEC TS 60904-1-2. Additionally informative annexes are provided concerning area measurement of PV devices, PV devices with capacitance, measurement of dark current-voltage characteristics (dark I-V curves) and effects of spatial non-uniformity. This standard is applicable to flat, non-concentrating PV devices for use in terrestrial environments, with reference to (normally but not exclusively) the global reference spectral irradiance defined in IEC 60904-3. It may also be applicable to PV devices for use under concentrated irradiation if the application uses direct sunlight and reference is instead made to the direct reference spectral irradiance in IEC 60904-3.
