ABSTRACT:
A thin-film solar cell has a two-layered transparent electrode formed on a transparent substrate, a photoelectric conversion section formed on the transparent electrode, and a back electrode formed on the photoelectric conversion section. The first layer of the transparent electrode is formed on the transparent substrate and is constituted of crystal grains having a large average diameter, while the second layer thereof is formed on the first layer and is constituted of crystal grains having a small average grain diameter. The sharp pointed tips of the coarse crystal grains of the first layer are covered by the fine crystal grains of the second layer so that the side of the transparent electrode in contact with the photoelectric conversion section presents a relatively smooth surface with rounded irregularities. Each layer is separately deposited on the respective transparent substrate.
