The utility model belongs to the technical field of solar energy glass, concretely relates to anti PID photovoltaic glass, include the anti - rete that subtracts of following last silica to setting gradually down and subtracting anti - rete, the two matte photovoltaic glass layers of low sodium calcium content and having cation separation agent layer. Because the anti - rete that subtracts of bottom has a cation separation agent layer, consequently effectual migration of having stopped metal cations in the subassembly, and then reduced the possibility that PID produced, its outdoor decay be far above common photovoltaic module on the market at present, greatly increased electric station side unit area generated energy.
