You could start here:
https://en.wikipedia.org/wiki/Wafer_(electronics)#Formation

This gives you a "blank" wafer. There are many steps in adding the electronic circuits on top of the wafer.
See: https://en.wikipedia.org/wiki/Integrated_circuit

Residential Solar Cells can use silicon of lower purity, and fewer fabrication steps.

By the way, on a visit to a nuclear reactor, I was surprised to see many silicon ingots in the reactor core, turning on a rotisserie arrangement. The neutrons from the reactor transmute some Silicon atoms into Phosphorus, producing Phosphorus-doped Silicon, even before the ingot is sawn into wafers.
