Abstract
A method includes supplying current to at least one photovoltaic device via a current source and detecting emitted photon radiations from the at least one photovoltaic device via a radiation detector. The method also includes outputting a signal corresponding to the detected emitted photon radiations from the radiation detector to a processor device, and processing the signal corresponding to the detected emitted photon radiations via the processor device 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.
