Abstract

The invention disclose flexible Dye-sensitized Solar Cells (DSSCs) based on a titanium dioxide nanometer rod array film. The DSSCs comprise flexible quasi-one-dimensional photoanodes, a dye sensitizing agent, electrolyte and flexible counter electrodes. The flexible quasi-one-dimensional photoanodes are composed of a flexible transparent conductive substrate, a TiO2 nanometer particle thin layer and a TiO2 nanometer rod array thin layer which are superposed from outside to inside. The TiO2 nanometer particle thin layer is closely connected with the flexible transparent conductive substrate. The TiO2 nanometer rod array thin layer grows on the TiO2 nanometer particle thin layer. Dye is absorbed on the TiO2 nanometer rod array. The flexible Dye-sensitized Solar Cells (DSSCs) in the invention have the advantages of increase of electron transmission speed, reduction of electron composite, portability and foldability.

Description

technical field [0001] The invention belongs to the technical field of dye-sensitized solar cells, and relates to a method for preparing a flexible dye-sensitized solar cell, in particular to a method for preparing a flexible quasi-one-dimensional photoanode. Background technique [0002] Solar power technology is widely used in scientific research and social life, and it is one of the possible ways to solve environmental pollution and energy crisis. Solar cells provide long-term and stable energy sources for artificial space vehicles such as space laboratories, spacecraft, and artificial satellites. Solar power stations, solar street lights, and solar traffic lights in daily life are being rapidly constructed and promoted. At present, most of the solar cells produced and applied on a large scale are crystalline silicon solar cells. Although such solar cells are environmentally friendly during use and will not pollute the environment, their manufacturing costs are high, the ...
