Abstract:
1. A method for forming a patterned layer from a common layer in a photovoltaic application, wherein the patterned layer is configured to form one or more portions of one or more solar cells on a rigid substrate, the method comprising: making a first pass with a first laser beam over an area on the common layer; and making a second pass with a second laser beam over approximately the same area on the common layer, wherein the first pass provides a first level of electrical isolation between a first portion and a second portion of the common layer; the second pass provides a second level of electrical isolation between the first portion and the second portion of the common layer, the second level of electrical isolation being greater than the first level of electrical isolation; and said substrate has a Young's modulus of 20 GPa or greater.
