Scope

What is BS EN IEC 60904-7 - Photovoltaic devices about? BS EN IEC 60904 series covers photovoltaic devices. BS EN IEC 60904-7 is one of the parts of a series of documents that describes the procedure for correcting the spectral mismatch error introduced in photovoltaic device testing, caused by a mismatch between the test spectrum and the reference spectrum, as well as a mismatch between the spectral responsivities (SR) of the reference device and the device under test, and thus reducing the systematic uncertainty. This procedure is applicable to single-junction devices, although the theory can be applied to multi-junction devices as well. The goal of BS EN IEC 60904-7 is to provide best practice guidance for correcting spectral mismatch errors that may occur between the test spectrum and the reference spectrum, as well as between the reference device SR and the device under test SR. The spectral mismatch correction generated is only valid for the specific combination of test and reference devices detected with a specific test spectrum. Who is BS EN IEC 60904-7 - Photovoltaic devices for? BS EN IEC 60904-7 on photovoltaic devices is applicable to: Photovoltaic devices manufacturers Telecommunication repeater stations. Water pumps Navigational aids Cottages and remote residences Parks in remote regions Supplying occasional power Why should you use BS EN IEC 60904-7 - Photovoltaic devices ? Photovoltaic devices device has a wavelength-dependent spectral responsivity, its performance is significantly affected by the spectral distribution of the incident radiation, which in natura...
