Abstract
An apparatus for inducing a current in a solar cell substrate. A substrate receiving surface receives the substrate, and an array of a plurality of individually addressable light sources illuminates the substrate in a sequenced manner. A sequencer controls the sequenced manner of illumination of the substrate by the array. A front side electrical contact makes electrical contact to a front side of the substrate, and a back side electrical contact makes electrical contact to a back side of the substrate. A meter is electrically connected to the front side electrical contact and the back side electrical contact, and senses the current induced in the substrate during the sequenced illumination of the substrate.
