Abstract
A method for manufacturing a solar cell can include forming a tunneling layer on first and second surfaces of a semiconductor substrate, the tunneling layer including a dielectric material; forming a polycrystalline silicon layer on the tunnel layer at the first surface and on the second surface of the semiconductor substrate; removing portions of the tunnel layer and the polycrystalline silicon layer formed at the first surface of the semiconductor substrate; forming a doping region at the first surface of the semiconductor substrate by diffusing a dopant; forming a passivation layer on the polycrystalline silicon layer at the second surface of the semiconductor substrate; and forming a second electrode connected to the polycrystalline silicon layer by penetrating through the passivation layer.
