摘要： A high-efficiency triple-junction thin-film photovoltaic device in which the haze ratio is high and the short-circuit current values obtained from each of the photovoltaic layers are equalized. A thin-film photovoltaic device comprises a transparent electrode layer and three silicon-based photovoltaic layers stacked in sequence on a substrate. The transparent electrode layer has at least one opening formed by an etching treatment that exposes the surface of the substrate, and the haze ratio of the transparent electrode layer relative to light of a broad wavelength region is at least 60%.
