A method of fabricating electrically isolated photovoltaic modules arrayed on a substrate by forming overlying front contact strips, photovoltaic strips, and back contact strips on a flat transparent substrate, laser scribing between modules to electrically isolate adjacent modules for the simultaneous testing and electrical curing of the modules on a single substrate, and plasma etching the inter-module grooves formed by the laser isolation step to improve the percentage of modules on a single substrate that pass minimum performance criteria. Also disclosed is an array of electrically isolated, thin-film semiconductor devices fabricated on a single substrate, wherein adjacent semiconductor devices are separated by laser-scribed grooves extending through the devices to the substrate and the walls of the grooves have been etched by plasma etching.
