Methods and related systems for fabricating a solar-cell assembly are provided. An example method comprises forming a series of layers and scribing a series of aligned interconnect lines in the layers prior to forming any isolation line related features. The example method provides for the use of contiguously-scribed interconnect lines as compared to an existing method where at least one interconnect line is segmented to avoid scribing through a previously-formed isolation line related feature located where an isolation line is to be scribed. The ability to use contiguously-scribed interconnect lines may improve the throughput of the fabrication process.
