Abstract: A method for manufacturing asolar cell includes texturing a front surface of a semiconductor substrate having a first conductive type dopant by using a dry etching method, forming an emitter layer by ion-implanting a second conductive type dopant into the front surface of the semiconductor substrate, forming a back passivation film on a back surface of the semiconductor substrate; and forming a first electrode electrically connected to the emitter layer and a second electrode being in partial contact with the back surface of the semiconductor substrate.

Abstract: A method for manufacturing a solar cell includes preparing a semiconductor substrate having a first conductivity type dopant; ion-implanting a pre-amorphization elements into a front surface of the semiconductor substrate to form an amorphous layer; and forming an emitter layer by ion-implanting second conductivity type dopant into the front surface of the semiconductor substrate. The method then further includes heat-treating the layers to activate the second conductivity type dopant. The method further includes forming a back surface field layer at a back surface of the semiconductor substrate by ion-implanting a first conductivity type dopant.
