Photovoltaic cell light-emitting principle diagram
How PV Cells Work
Diagram of a photovoltaic cell. Regardless of size, a typical silicon PV cell produces about 0.5 – 0.6 volt DC under open-circuit, no-load conditions. The current (and power) output of a PV cell depends on its efficiency and size (surface area), and is proportional to the intensity of sunlight striking the surface of the cell.
