Abstract

The invention discloses a perovskite nanowire solar cell with tiled shell-core structures. Sunlight can directly enter from the front surface of the cell without entering from the side surface of thecell, and therefore, device efficiency is improved, and the perovskite nanowire solar cell with the tiled shell-core structures is very suitable for the fields of intelligent wearing and the like. Theinvention discloses a perovskite nanowire solar cell with the tiled shell-core structures comprises a sheet-shaped substrate; a strip-shaped first electrode and a strip-shaped second electrode are respectively arranged at two ends of the substrate; the first electrode and the second electrode are parallel to each other; a plurality of shell-core structure perovskite nanowires are arranged betweenthe first electrode and the second electrode along a planar array; the shell-core structure perovskite nanowires are parallel to each other; each shell-core structure perovskite nanowire comprises acore layer made of a transmission material and a shell layer made of a perovskite material, wherein the core layer is connected with the first electrode, and the shell layer is connected with the second electrode.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a perovskite nanowire solar cell with a flat shell-core structure. Background technique [0002] Nanowires with perovskite materials as the shell and transport materials as the core layer are expected to obtain high photoelectric conversion efficiency when used in solar cells. At present, the traditional shell-core structure nanowire arrays are all upright structures. If the shell-core structure perovskite nanowire arrays with perovskite materials as the light-absorbing layer are applied to solar cells, sunlight needs to be incident from the side of the cell. , affecting the performance of the device. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a flat shell-core structure perovskite nanowire solar cell, sunlight does not need to be incident from the side but can be directly incident fr...
