Description

technical field [0001] The invention relates to a preparation method of a large-area flexible dye-sensitized solar cell based on a titanium foil mesh, belonging to the fields of new material technology and energy technology. Background technique [0002] Flexible dye-sensitized solar cells are a new type of photoelectric conversion device, which has the advantages of bendability, light weight, good flexibility, impact resistance, low cost, and various shapes or surface designs, and can be used for some rigid dye-sensitized solar cells. For special curved surface occasions where solar cells are difficult to handle, such as pasting on the surface of other objects (such as car glass, clothes, etc.), it is especially suitable for use on some portable devices. Technologies such as continuous production in rolls and rapid coating can be used to facilitate large-area production, reduce production costs, have strong competitiveness, and have broad application prospects. The key to ...
