How a solar panel works
Your solar panel is protective glass encasing a conductive layer (Sn02) which then encases Titanium Dioxide and a sensitized dye on the top and a catalyst. Between that is an electrolyte. The conductive layer is where the electrons move in or out and the electrical production happens in the three sandwiched layers.
When a photon from light strikes the top layer of the panel, this causes a release of electrons into the conductive layer and this means a current is flowing. At the same time, electrons are entering the bottom conductive layer (not the same electrons that entered because the usual electron speed is usually 10^(-4) m/s). The catalyst aids the electron's entrance into the electrolyte. In the electrolyte, the electron interacts with a Tri-Iodide molecule. When there is a Iodide ion, the Iodide ion transfers electrons back to the first layer and becomes Tri-Iodide molecule, and this is where the process repeats again.
With a bit of additional research I did at the time, I believe it's called the photovoltaic effect. I'm not exactly an expert, so anyone with more knowledge than me on this is welcome to chime in. I was just interested in knowing how a solar panel works, so I looked up a video. Anyway, even if I'm wrong, consider it a bump.
