Abstract
Solar cells and methods for fabrication thereof are provided. A method may include forming a via through at least one dielectric layer formed on a semiconductor wafer by using a laser to ablate a region of the at least one dielectric layer such that at least a portion of the surface of the semiconductor wafer is exposed by the via. The method may further include applying a self-doping metal paste to the via. The method may additionally include heating the semiconductor wafer and self-doping metal paste to a temperature sufficient to drive at least some dopant from the self-doping metal paste into the portion of the surface of the semiconductor wafer exposed by the via to form a selective emitter region and a contact overlying and self-aligned to the selective emitter region.
