What is PD IEC TS 60904-1-2-Current-voltage characteristics of bifacial PV devices about?
The IEC 60904 series discusses photovoltaic devices. PD IEC TS 60904-1-2 is one of the parts of a series of documents that specifies 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.
PD IEC TS 60904-1-2 is 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 direction normal reference spectrum is performed.
The requirements for measurement of I-V characteristics of standard (monofacial) PV devices are covered by IEC 60904-1, whereas PD IEC TS 60904-1-2 describes the additional requirements for the measurement of I-V characteristics of bifacial PV devices.
Who is PD IEC TS 60904-1-2-Current-voltage characteristics of bifacial PV devices for?
PD IEC TS 60904-1-2 on photovoltaic devices is applicable to:
- Photovoltaic device manufacturers
- Solar energy engineering
- Energy rating technology providers
- Solar photovoltaic energy systems
- Manufacturers of solar cells and solar panels
- Manufacturers of solar-based electrical devices
- PV power stations
Why should you use PD IEC TS 60904-1-2-Current-voltage characteristics of bifacial PV devices?
Bifacial photovoltaic device generates electricity when lit on both its front and back surfaces. Monofacial solar cells, on the other hand, only produce electrical energy when photons impinge on their front side. The accurate measurement of current-voltage characteristics are critical for the assessment of output power and efficient energy production of the PV device. In this regard, PD IEC TS 60904-1-2 sets limits on the permissible deviations for obtaining valid measurements.
PD IEC TS 60904-1-2-compliant best industry procedures for I-V measurement contributes to the efficient performance of the PV device.
