Abstract
The present invention generally relates to an edge deletion module positioned within an automated solar cell fabrication line. The edge deletion module may include a grinding wheel device for removing material from edge regions of a solar cell device and cleaning the edge regions of the solar cell device after removing the material. The edge deletion module may also include an abrasive element, a portion of which is ground as it is periodically, laterally advanced toward the grinding wheel device.
