To make a basic solar cell, we start with a metal conductive plate, this forms the positive electrode. On top of this we find a thin silicon layer. This is our semiconductor material. Typically, this consists of a layer of silicon boron mixture on the bottom and a layer of silicon phosphorus on top. The joint between them is known as the PN .

In this first step, crushed quartz is put in a special furnace, and then a carbon electrode is applied to generate a high-temperature electric arc between the electrode and the silicon dioxide. That process, called carbon arc welding (CAW), reduces the oxygen from the silicon dioxide and produces carbon dioxide at the electrode and molten silicon.

This creates “electron holes” – regions of mobile positive charge in the crystal structure. At the interface of the p- and n- type silicon, the positive electron holes and the electrons combine.
