Photoelectricity and superconductivity

I am not a physicist, continuing my wonder about superconductivity.

If I understand concepts properly,

photoelectricity: when light of certain frequency or higher strikes
surface of some materials, electric voltage is generated

superconductivity: superconductors have zero voltage drop across their
surface no matter how much current flows through

What happens when superconductor material is subjected to conditions
leading to photoelectricity? The material is supposed to generate
voltage but it can't, right?

Thanks in advance,
