1. An anti-Potential Induced Degradation (PID) encapsulation adhesive film for a photovoltaic module comprising a plurality of photovoltaic cells comprising gaps between the photovoltaic cells, comprising:
a base adhesive film layer;
an insulating layer, located on one side surface of the base adhesive film layer, the insulating layer having a grid structure comprising grid lines and a plurality of hollow portions defined by the grid lines, and the grid lines having a structure corresponding to gaps between the photovoltaic cells; and
a conductive layer, comprising a plurality of conductive portions, the conductive portions being arranged in the hollow portions in one-to-one correspondence, and the volume resistivity of the conductive portions being less than 100 Ω·cm;
wherein, the width of the grid lines is greater than the width of the gaps between the photovoltaic cells.
