1、Designation:E102115Standard Test Method forSpectral Responsivity Measurements of PhotovoltaicDevices1This standard is issued under the fixed designation E1021;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.
2、A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method is to be used to determine either theabsolute or relative spectral responsivity response of a single-junction photovolta
3、ic device.1.2 Because quantum efficiency is directly related to spec-tral responsivity,this test method may be used to determine thequantum efficiency of a single-junction photovoltaic device(see 10.10).1.3 This test method requires the use of a bias light.1.4 The values stated in SI units are to be
