And no don’t say “cells generate electricity” Yes I know that, but what chemical or whatever process makes it that sunlight is converted to electricity?
I have been wondering this all my life an no matter how much research I do I can’t seem to find the answer, every place just says that some cells inside the panels is what generates electricity, but not how those cells do it

A solar panel is basically just a reverse LED. An LED creates light by letting electrons flow from a high energy state to a low energy state (through a diode). This process can be reversed. If you strike an LED (or any diode) with a photon, an electron can travel from a low energy state to a high energy state and that energy can be collected by a battery.
