  • Publication number: 20210066531
    Abstract: The present disclosure provides a flexible solar cell and a manufacturing method thereof. The manufacturing method includes disposing a flexible substrate on a back electrode to transfer to the solar cell unit and the flexible substrate onto a temporary substrate, and then separating the temporary substrate from the flexible substrate after the flexible solar cell is manufactured. Thus, it reduces tedious bonding and de-bonding operations in manufacturing process of the flexible solar cell, can improve production efficiency, and avoids damage of cells by a high-temperature condition required for bonding. Also, the process is quick and not easy to damage the solar cell. The front electrode, back electrode and flexible substrate in the flexible solar cell all can be prepared by plating, with a relatively low cost and low requirement for equipment, which is conductive to mass production in industry.
