How can a photon move an electron if it has no mass?

I’m trying to understand how a solar panel works but I’m having trouble. How can something with no mass move something with mass?

Tldr: the object causing the electrons to move is actually a distant electron in the light source. The photon is basically the “force”

A photon is actually a disturbance in the electric/magnetic field. It has more in common with a FORCE, not an object.

An electron can cause another electron to move without touching it using an electric field. So an electron the light source shifted. This means other electrons will be shifted as it’s electric field is now over there. This shift in the field travels outwards, very quickly, as a light wave (or photons). When it reaches the distant electrons they shift and jiggle in response.
