Abstract
A solar cell fabrication procedure is described which is characterized by (1) forming a front surface mask in the configuration of the front surface electrodes, (2) a passivation step which, inter alia, results in the formation of an altered silicon substrate surface layer in the areas not covered by the front surface mask, (3) removal of the front surface mask, and (4) the use of the altered surface layer as a plating mask for subsequent metallization steps.
