    • An object is to provide a photoelectric conversion element with high conversion efficiency. In a photoelectric conversion element with a fine periodic structure on a light-receiving surface side, focus is given to the traveling direction of light that is reflected off another surface. The photoelectric conversion element may be given a structure in which a textured structure that reflects light to the other surface is provided, and light that travels from the light-receiving surface side to the other surface side is reflected so that a component that travels along the photoelectric conversion layer increases. By the distance traveled by the reflected light inside the photoelectric conversion layer increasing, the light that enters the photoelectric conversion element is more easily absorbed by the photoelectric conversion layer and less easily released from the light-receiving surface side, and a photoelectric conversion element with high conversion efficiency can be provided.
    • 目的在于提供高转换效率的光电转换元件。 在受光面侧具有微细周期结构的光电转换元件中,对从另一面反射的光的行进方向进行聚焦。 可以给光电转换元件提供将光反射到另一表面的纹理结构,并且从受光面侧行进到另一个表面侧的光被反射,从而沿着 光电转换层增加。 通过光电转换层内的反射光行进的距离增加,进入光电转换元件的光更容易被光电转换层吸收,并且不容易从光接收表面侧释放,并且具有 可以提供高转换效率。

    • An object is to provide a photoelectric conversion device which has little loss of light absorption in a window layer and has high conversion efficiency. A photoelectric conversion device including a crystalline silicon substrate having n-type conductivity and a light-transmitting semiconductor layer having p-type conductivity between a pair of electrodes is formed. In the photoelectric conversion device, a p-n junction is formed between the crystalline silicon, substrate and the light-transmitting semiconductor layer, and the light-transmitting semiconductor layer serves as a window layer. The light-transmitting semiconductor layer includes an organic compound and an inorganic compound. As the organic compound and the inorganic compound, a material having a high hole-transport property and a transition metal oxide having an electron-accepting property are respectively used.
