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 made of two layers of silicon with small amounts of another element added that make one layer more attractive for electrons than the other.
When an electron is hit by a photon of sunlight, it can get knocked into the less-attractive layer. From there, the electron takes the “path of least resistance” through the circuit the solar cell is powering to get back to the more-attractive layer.
