Abstract:
A photovoltaic device comprising a transparent conductive film, a semiconductor thin film, and a metallic electrode film successively deposited on one surface of a transparent substrate, characterized in that,the thickness distribution of said transparent conductive film is in a range of Â±10% of a central film thickness, a transparent thin film comprising at least one layer and having a refractive index ranging from 1.45 to 1.8 and a thickness ranging from 20 to 80 nm is deposited between said transparent substrate and said transparent conductive film, and a* and b* of a reflected color from the transparent substrate to which light is applied may vary within a range of Â±5 of a* and b*, where a* and b* indicate chromaticness indexes in L*a*b* colorimetric system provided for according to JIS Z 8729-1980.
