Zusammenfassung:	A method and apparatus for manufacturing photovoltaic cells is provided. In one embodiment, a method for evaluating transparent conductive oxide (TCO) delamination from a substrate is provided. The method comprises providing a glass substrate with a TCO film laminated on a first surface of the glass substrate, depositing a metal layer on a second surface of the glass substrate opposite the first surface, heating the substrate while applying a bias to the substrate, cooling the substrate in a humidity controlled environment for a fixed time period, dividing the TCO film into a plurality of electrically insulated channels using a laser scribing process, and measuring a resistance of each of the plurality of electrically insulated channels.
