Abstract
A solar cell can include a silicon semiconductor substrate having a first conductive type; a oxide layer on a first surface of the silicon semiconductor substrate; a polysilicon layer on the oxide layer and having the first conductive type; an emitter region at a second surface of the silicon semiconductor substrate opposite to the first surface and having a second conductive type opposite to the first conductive type; a first passivation film on the polysilicon layer; a first electrode connected to the polysilicon layer through an opening formed in the first passivation film; a second passivation film on the emitter region; and a second electrode connected to the emitter region through an opening formed in the second passivation film.
