Scope

This document specifies the correction calculation method for spectral mismatch errors in photovoltaic device testing caused by the test spectrum not matching the standard spectrum (such as the AM 1.5 spectrum) and the spectral response (SR) of the standard device not matching that of the device under test, with the aim of reducing the system's uncertainty. This document is applicable to spectral mismatch correction for single-junction photovoltaic devices, and multi-junction photovoltaic devices can refer to it for use.
