    摘要: A method of manufacturing a photovoltaic device includes preparing a semiconductor substrate having a light incidence surface receiving light and including single crystalline silicon, wet-etching the light incidence surface to form a plurality of first protrusions on the light incidence surface, dry etching a plurality of surfaces of the first protrusions to form a plurality of second protrusions on the plurality of surfaces of the first protrusions, and forming a semiconductor layer on the light incidence surface. The method further includes forming a first electrode on the semiconductor layer and forming a second electrode on a rear surface of the semiconductor substrate facing the light incidence surface.
