Abstract: A photoelectronic device includes an active layer containing inorganic particles, and an oxide semiconductor layer containing zinc (Zn), silicon (Si), and oxygen (O), where the oxide semiconductor layer and the active layer are stacked layers. The photoelectronic device further includes a multilayer transparent electrode over or under the active layer, wherein the oxide semiconductor layer serves as a part of the multilayer transparent electrode.
