Photoelectric effect
In photoelectric effect, we sometimes add a battery to increase/decrease kinetic energy of photoelectrons
But can a battery connected such that its negative terminal is facing the plate with light (its potential decreases but electrons gain potential energy due to negative charge) give enough potential energy to electrons that they emit without interacting with photons at all?
I mean there will be a high amount of force towards other plate due to electric field on them and they could certainly gain enough potential to easily overcome the work function, then why need photons at all?
Is it just because system wont move by itself and electrons just need a little push through photons?
