Abstract
A photovoltaic device includes an i-type amorphous silicon thin film and a p-type amorphous silicon thin film arranged on portions of an n-type crystalline silicon substrate, a collecting electrode arranged on the amorphous silicon thin film, and an insulating layer arranged around the portions where the amorphous silicon thin film is formed. Thus, a pin junction is formed only below the collecting electrode.
