Luminescence techniques, both electroluminescence (EL) and photoluminescence (PL), are becoming powerful tools for inspecting solar cells and photovoltaic modules, 1-7 based on the reciprocity relation between photovoltaic quantum efficiency and luminescence emission. 8,9 EL consists of luminescence emission by solar cells under forward bias, 10 thereby spatially resolving defects that affect the performance and/or durability of the modules, such as cracks, heterogeneous cell activity, failed soldering, grid defects, and dark areas in cells associated with dislocation clusters. 11-18 In contrast, PL consists of luminescence emission under excitation with light. 19-28 The difficulty involved in obtaining a uniform large-area light excitation source over the module surface has prevented it from being applied to module inspection. This problem was circumvented by using the sun as the excitation source, without having to resort to an artificial light source, for example, a laser. 19,29 PL emission depends on the quality of the material, its defects, for example, dislocations, precipitates, and cracks,
