Abstract
The present application provides effective and efficient structures and methods for the formation of solar cell base and emitter regions and passivation layers using laser processing. Laser absorbent passivation materials are formed on a solar cell substrate and patterned using laser ablation to form base and emitter regions. Laser damage to the solar cell substrate is removed using an etch.
