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.

Effect of Temperature

The short-circuit current, I sc, increases slightly with temperature since the bandgap energy, E G, decreases and more photons have enough energy to create e-h pairs. However, this is a small effect, and the temperature dependence of the short-circuit current from a silicon solar cell is typically; or 0.06% per °C for silicon.
