Abstract

Electroluminescence imaging is extended to the photovoltaic (PV) module level. Qualitative characterisation of different types of commercially available PV devices is made based on electroluminescence measurements and photographic images. Examples include a conventional crystalline silicon PV module, a chalcopyrite PV module, a cadmium telluride PV module, an amorphous silicon single junction PV module, a tandem micromorph silicon PV module, and a flexible triple junction silicon PV module. For each type of module the discussion focuses on their topology and general electroluminescence intensity distribution, as well as a description of observed inhomogeneities.
