Abstract: A flexible transparent copper circuit, a preparation method therefor, and a application thereof. The preparation method specifically comprises the following steps: (1) uniformly coating a gel containing copper powder on one side of a glass sheet, and drying same to form a copper film layer; and (2) placing the one side of the glass sheet coated with the copper film layer opposite to a polymer material, scanning the other side using a laser beam such that the copper film layer is transferred to a suropposite to of the polymer material, and performing post-processing to obtain a flexible transparent copper circuit. The copper circuit obtained by the preparation method has good potential in flexible photovoltaic applications. Moreover, since laser processing has fast speed and inherent flexibility, the transferred metal circuit can be freely designed, thus improving the processing efficiency and facilitating mass production.
