Abstract
A method of manufacturing a solar cell including providing a semiconductor substrate having a first conductivity type; performing a first deposition process that includes forming a first doping material layer having a second conductivity type different from the first conductivity type; performing a drive-in process that includes heating the substrate having the first doping material layer thereon; performing a second deposition process after performing the drive-in process and including forming a second doping material layer on the first doping material layer, wherein the second doping material layer has the second conductivity type; locally heating portions of the substrate, the first doping material layer, and the second doping material layer with a laser to form a contact layer at a first surface of the substrate; and forming a first electrode on the contact layer and a second electrode on a second surface of the substrate opposite to the first surface.
