<p>The invention discloses a method for the production of a solar cell with fired rear side contacts and with via holes perforating the cell for the contacting of a front side located emitter layer with rear side located busbars. According to the invention, during the fabrication of the via holes, a simultaneous doping of the via holes takes place. Preferably, this is achieved by means of liquid jet-guided laser processing. Furthermore, the invention discloses a metal wrap through (MWT) or emitter wrap through (EWT) solar cell with fired rear side contacts and with via holes, particularly obtained according to the invention's method, the cell having a void-free, pure and smooth metallic layer on at least the walls of the via holes.</p> |
