Abstract
Laser-absorbing seed layers for solar cell conductive contacts and methods of forming solar cell conductive contacts are described. For example, a method of fabricating a solar cell includes forming a metal seed paste above a substrate. The metal seed paste includes a laser-absorbing species. The metal seed paste is irradiated with a laser to form a metal seed layer. The irradiating includes exciting the laser-absorbing species. A conductive contact for the solar cell is then formed from the metal seed layer.
