    摘要: A solar cell is disclosed. The solar cell includes an n-type or p-type amorphous silicon layer, a transparent electrode, and a metal buffer layer between the transparent electrode and the amorphous silicon layer. The metal buffer layer contains at least one of In, Sn, B, Al, Ga, and Zn. When the transparent electrode contains indium tin oxide (ITO), the metal buffer layer contains at least one of In and Sn. When the transparent electrode contains zinc oxide, the metal buffer layer contains at least one of B, Al, Ga, and Zn.

    摘要: A solar cell includes a first conductivity type crystalline semiconductor substrate, a first amorphous silicon region, a first electrode, and a second electrode. The crystalline semiconductor substrate may include a plurality of pyramidal-shaped projections or a plurality of reverse-pyramidal shape depressions on at least one surface thereof. The first amorphous silicon region may be positioned on the crystalline semiconductor substrate and have a second conductivity type opposite the first conductivity type. The first electrode may be positioned on the first amorphous silicon region, and a second electrode positioned on the substrate. At least one pyramidal-shaped projection or at least one reverse-pyramidal shape depression may include two adjacent inclination surfaces, and a rounded edge portion where the two adjacent inclination surfaces meet.
