The present disclosure relates to optical methods and systems for detecting defects in photovoltaic (PV) devices such as PV cells, PV panels, PV modules, and PV arrays. These methods include may include illuminating a first portion of the surface such that the illumination causes formation of a voltage within the device and the voltage induces luminescence in a second portion of the surface that is different from the first portion, and the first and second portions do not substantially overlap. The methods also include detecting the luminescence in the second portion of the surface, and from the detecting, determining the presence or absence of one or more defects in the second portion of the surface. |
