Disclosed is a high-performance repair tape for a backboard of a photovoltaic module. The tape comprises a base material layer, a functional adhesive layer, and a release material layer provided in sequence from top to bottom; the base material layer is formed of a polyester thin film material; the functional adhesive layer is formed of a high weather-resistance adhesive. According to the high-performance repair tape for a backboard of a photovoltaic module, and a manufacturing method therefor provided by the present invention, by selecting a weather-resistant base material layer, effects, such as water resisting, insulation, and ultraviolet radiation resistance, can be achieved, and a backboard independence effect is achieved; by selecting a weather-resistant adhesive for the functional adhesive layer, the weather resistance, high temperature resistance, and yellowing resistance of the tape can be improved; the tape has a strong bonding strength and is not easy to peel off, and the tape is easy to fit and facilitates construction.
