Abstract

The purpose of the present invention is to improve the reliability of a photovoltaic cell. In the present invention, a photovoltaic cell (CL) comprises a back electrode (BE), a p-type semiconductor layer (semiconductor substrate 1S) disposed on the back electrode (BE), and an n-type semiconductor layer (NL) disposed on the semiconductor substrate (1S). The photovoltaic cell (CL) furthermore comprises: an anti-reflection film (ARF) disposed on the n-type semiconductor layer (NL), the anti-reflection film (ARF) being made of an insulating film; surface electrodes (SE) penetrating the anti-reflection film (ARF) to reach the n-type semiconductor layer (NL); and an electroconductive film (CF) disposed on the anti-reflection film (ARF) so as to cover the surface electrodes (SE), the electroconductive film (CF) being transparent and being electrically connected to the n-type semiconductor layer (NL).
