Abstract:
1. An ion implanter for processing a solar cell, the ion implanter comprising: an ion source for generating ions; a target support disposed downstream of the ion source for supporting the solar cell in a target plane; a mask disposed between the ion source and the target support, the mask including a front surface, a back surface, at least one aperture extending from the front surface to the back surface and along an aperture direction, and a side surface extending from the front surface to the back surface to define the at least one aperture, wherein at least a portion of the side surface is non-perpendicular to at least one of the front and back surfaces; and a beam-line component for directing ions to the solar cell along an ion beam path, wherein the ion beam path is non-parallel relative to the aperture direction.
