Video: Photovoltaics - Solar Cell EL Inspection At 60fps

This video shows a movie of a small solar cell section being driven to luminance by a square wave pulse from a function generator running at 1 Hz. The image was captured under dim lighting conditions with the high-sensitivity Goodrich InGaAs KT camera, using high gain with 16 ms exposures while recording at 60 frames per second (fps). Note the structure evident in the luminescent image, including the obvious dead areas.
