The present technology relates to multi-cell devices fabricated on a common substrate that are more desirable than single cell devices, particularly in photovoltaic applications. Multi-cell devices operate with lower currents, higher output voltages, and lower internal power losses. Prior art multi-cell devices use physical isolation to achieve electrical isolation between cells. In order to fabricate a multicell device on a common substrate, the individual cells must be electrically isolated from one another. In the prior art, isolation generally required creating a physical dielectric barrier between the cells, which adds complexity and cost to the fabrication process. The disclosed technology achieves electrical isolation without physical isolation by proper orientation of interdigitated junctions such that the diffusion fields present in the interdigitated region essentially prevent the formation of a significant parasitic current which would be in opposition to the output of the device.
