Edge isolation

Therefore, following diffusion, an edge isolation process is required to remove the unwanted diffusion around the edges of the solar cell, and electrically isolate the front and rear surfaces. This can be done in one of three ways: Plasma etching. In this process, the samples are stacked on top of one another such that only their edges are exposed.
