What is BS EN 60904-1-1-Multi-junction photovoltaic (PV) devices about?
BS EN 60904-1-1 specifies procedures for the measurement of the current-voltage characteristics of multi-junction photovoltaic devices in natural or simulated sunlight. It is applicable to single PV cells, sub-assemblies of such cells or entire PV modules. It is principally intended for non-concentrating devices, but parts may be applicable also to concentrating multi-junction PV devices. An essential prerequisite is the spectral responsivity of the multi-junction devices, whose measurement is covered by IEC 60904-8-1.
BS EN 60904-1-1 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 spectral irradiance distribution is performed. The reference spectral irradiance distribution is provided in IEC 60904-3.
Who is BS EN 60904-1-1-Multi-junction PV devices for?
BS EN 60904-1-1 on multi-junction photovoltaic devices is useful for:
- Toys, watches, manufacturers
- Electric fence manufacturers
- Remote lighting systems manufacturers
- portable power supplies
- Satellites and aerospace
- Multi-junction photovoltaic (PV) devices manufacturers
Why should you use BS EN 60904-1-1-Multi-junction photovoltaic (PV) devices?
Multi-junction photovoltaic devices are capable of absorbing different wavelengths of incoming sunlight by using different layers, making them more efficient at converting sunlight into electricity than single-junction cells.
Guidance in BS EN 60904-1-1 can help you to design and manufacture efficient multi-junction PV devices.
Guidance for the measurement of the spectral responsivity in BS EN 60904-1-1 can help you achieve the reliability and efficiency in multi-junction photovoltaic PV device assemblies.
