Abstract

An all-solid-state photoelectric conversion device and a preparation method thereof. The photoelectric conversion device is of a Zn-ZnO-Ag structure. A lower layer of the photoelectric conversion device is a Zn sheet, a middle layer is a ZnO film, and an upper layer is a Ag film deposited on the ZnO film. The ZnO film is poriform, and is generated on the Zn sheet located at the lower layer by anodizing. The ZnO film is black blue poriform, the diameter is 30 to 100nm, and the thickness is 2.6 to 5.0[mu]m. Low-cost anodizing technology is adopted to realize preparation of a heterogeneous layer, through AG film modification, an all-solid-state photoelectric conversion device having sunlight response is obtained, and the method provides possibilities of use of the photoelectric conversion device under various conditions and large-scale production, and thus can alleviate energy pressure.
