Abstract:
A solar cell includes a silicon substrate, an emitter area formed on a front surface of the silicon substrate, a tunneling oxide layer formed on a back surface of the silicon substrate, a back surface field area formed on the tunneling oxide layer and formed of a polycrystalline silicon layer, a back passivation film formed on the back surface field area and having an opening, and a back electrode connected to the back surface field area via the opening.
