Abstract: A method for forming electrical contacts for a solar cell and a solar cell formed using the method is provided. The method includes forming a first metal layer over predefined portions of a surface of the solar cell; depositing a carbon nanotube layer over the first metal layer; and forming a second metal layer over the carbon nanotube layer, wherein the first metal layer, the carbon nanotube layer, and the second metal layer form a first metal matrix composite layer that provides electrical conductivity and mechanical support for the metal contacts.
