Abstract
The present invention provides methods of manufacturing a high efficiency solar cell. In one embodiment, in a solar cell having a grid pattern that channels current, a defect causes an undesired current flow is removed by mechanically removing a portion of the grid pattern, thereby passivating the defect by removing a segment of the solar cell adjacent the defect. The segment also includes the front and back portions of the solar cell at the location of the defect without including the defect.
