What is in the potato that makes electricity?

Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte.

Also to know is, why is a potato conductor of electricity?

To be clear, the potato is not, in and of itself, an energy source. What the potato does is simply help conduct electricity by acting as what's called a salt-bridge between the the two metals, allowing the electron current to move freely across the wire to create electricity.
