Abstract
Disclosed are a solar cell and a method for manufacturing the same. A solar cell includes a semiconductor substrate, a tunnel layer on the first surface of the semiconductor substrate, a first conductive type semiconductor region on the tunnel layer and includes impurities of a first conductive type, a second conductive type semiconductor region on a second surface and includes impurities of a second conductive type opposite the first conductive type, a first passivation film on the first conductive type semiconductor region, a first electrode formed on the first passivation film and connected to the first conductive type semiconductor region through an opening portion formed in the first passivation film, a second passivation film on the second conductive type semiconductor region, and a second electrode formed on the second passivation film and connected to the second conductive type semiconductor region through an opening portion formed in the second passivation film.
