Problems solved by technology

At present, the matrix used to assemble perovskite solar cells is mainly conductive glass, which not only affects its preparation efficiency, but also limits its application in flexible devices; its structure mainly has mesoporous and planar types, which is not conducive to improving the performance of devices. The stability of the interface is still unable to capture the change information before and after the illumination of each interface

Abstract

The invention relates to a manufacturing method of a flexible all-solid-state array type perovskite solar battery, and belongs to the technical field of nano-thin film preparation and photo-electrochemical characteristics. By means of the pulse anodic oxidation technology, a titanium dioxide nanotube array with the controllable structure and the sequential arrangement heights is prepared on a flexible substrate made of titanium foil and the like, and the solution method is adopted for implanting perovskite sensitizers and solid electrolytes in titanium dioxide nanotubes to form a coaxial array; on the basis, the perovskite solar battery is assembled on the flexible substrate. The composite thin film prepared with the method is used for the perovskite solar battery, and photoelectric conversion efficiency of the perovskite solar battery reaches 0.64%.

Description

technical field [0001] A method for preparing a flexible all-solid-state array type perovskite solar cell belongs to the technical field of nano-film preparation and photoelectrochemical characteristics. Background technique [0002] Perovskite solar cells are known as the arrival of a new era in the field of photovoltaics due to their advantages such as low raw material cost, high photoelectric conversion efficiency and simple preparation process. At present, the matrix used to assemble perovskite solar cells is mainly conductive glass, which not only affects its preparation efficiency, but also limits its application in flexible devices; its structure mainly has mesoporous and planar types, which is not conducive to improving the performance of devices. The stability of the system cannot capture the change information of each interface before and after illumination. Contents of the invention [0003] The invention provides a method for preparing a flexible all-solid-sta...
