Abstract

A method for fabricating a solar cell generally comprises delivering a solar cell substructure to a chamber. Electromagnetic radiation is generated using a wave generating device that is coupled to the chamber such that the wave generating device is positioned proximate to the solar cell substructure. The electromagnetic radiation is applied onto at least a portion of the solar cell substructure to facilitate the diffusion of at least one metal element through at least a portion of the solar cell substructure such that a semiconductor interface is formed between at least two different types of semiconductor materials of the solar cell substructure.
