The method also includes outputting a signal corresponding to the detected emitted photon radiations from the radiation detector (16) to a processor device (18), and processing the signal corresponding to the detected emitted photon radiations via the processor device (18) to generate one or more two-dimensional photon images. The method further includes analyzing the one or more two-dimensional photon images to determine at least one defect in the at least one photovoltaic device (12).2/8 10 16 19 Radiation Frame detector trigger grabber device 18 EL Low pass Filter Processor device 12 Current Signal source generator 14 FIG. 2
