1) A typical silicon PV cell is composed of the following:
- A thin wafer of silicon doped with phosphorus: (n-type) silicon.
- A thicker layer of silicon doped with boron: (p-type) silicon.
- An electrical field created where these two materials are in contact, called the p-n junction.

2) A typical silicon PV cell produces about 0.5–0.6 volt DC under open-circuit, no-load conditions.
3) The current (and power) output of a PV cell depends on:
- Cell efficiency.
- Cell size (surface area).
- The intensity of sunlight striking the surface of the cell.
- Cell efficiency.
- Cell size (surface area).
- The intensity of sunlight striking the surface of the cell.
