Photovoltaic devices - Part 13: Electroluminescence of photovoltaic modules

IEC TS 60904-13:2018(E) specifies methods to: - capture electroluminescence images of photovoltaic modules, - process images to obtain metrics about the images taken in quantitative terms, and - provide guidance to qualitatively interpret the images for features in the image that are observed. This document is applicable to PV modules measured with a power supply that places the cells in the modules in forward bias.
