If the Sahara desert were covered in solar panels, could it power the entire earth?

Assuming no loss in transmission just for ease-of-calculation purposes, covering ~12% of the Sahara Desert with solar panels, assuming 40% (typical) density, would supply the energy needs of the entire planet currently (pun intended). Nope, not just electricity use. All energy.

And no, I didn’t read the comments. I don’t care what they say as they are almost alway wrong about questions like this.
