Photon imaging system for detecting defects in photovoltaic devices, and method thereof

摘要

A method includes supplying current to at least one photovoltaic device (12) via a current source (14) and detecting emitted photon radiations from the at least one photovoltaic device (12) via a radiation detector (16). 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).
