Description

technical field [0001] The invention belongs to the technical field of transparent electrode manufacture, and in particular relates to a flexible transparent electrode with ultraviolet filtering function. Background technique [0002] Transparent conductive electrodes are important components of various electronic devices, including touch screens, displays, and thin-film solar cells. At present, transparent conductive electrodes generally use metal oxides, such as ITO thin films. Due to the limited reserves of some key metal elements in oxide electrodes, such as indium, and the need for vacuum coating equipment and technology for metal oxide films, these factors lead to rising costs of the electrodes; more critically, due to the intrinsic brittleness of metal oxides, etc., As a result, it cannot be applied to the emerging flexible devices, such as flexible thin-film solar cells, flexible touch screen displays, and electronic skins. Flexible transparent electrodes refer to ...
