Abstract
A method of laser scribing a CdTe solar cell structure includes providing a laser operable to produce an optical pulse. The optical pulse is characterized by a temporal profile having a first power level during a first portion of the optical pulse and a second power level less than the first power level during a second portion of the optical pulse. The method also includes directing the optical pulse to impinge on the CdTe solar cell structure. The CdTe solar cell structure includes a substrate, a transmission spectrum control layer adjacent the substrate; a barrier layer adjacent the transmission spectrum control layer, and a conductive layer adjacent the barrier layer. The method further includes initiating a removal process for the conductive layer and terminating the removal process prior to removing the barrier layer.
