Abstract:
A method for manufacturing a solar cell according to an embodiment of the invention includes forming an emitter layer having an emitter dopant of a second conductive type opposite to a first conductive type on a first surface on a semiconductor substrate; forming a passivation layer including a first dopant of the first conductive type on a second surface of the semiconductor substrate; forming a back surface field layer including a first portion on the second surface by locally heating a portion of the passivation layer using a laser; and forming an electrode electrically connected to the first portion of the back surface field layer through an opening of the passivation layer after the first portion of the back surface field layer is formed on the second surface, wherein the back surface field layer is locally formed between the electrode and the second surface.
