The short-circuit current is due to the generation and collection of light-generated carriers. For an ideal solar cell at most moderate resistive loss mechanisms, the short-circuit current and the light-generated current are identical. Therefore, the short-circuit current is the largest current which may be drawn from the solar cell.

The solar cell is the basic building block of solar photovoltaics. The cell can be considered as a two terminal device which conducts like a diode in the dark and generates a photovoltage when charged by the sun. When the junction is illuminated, a net current flow takes place in an external lead connecting the p-type and n-type regions.

As a result of the everincreasing share of renewable energy sources the short circuit current in the future will differ from the status quo.
To generate power, fuel is contiguously burned in a ceramic tube which glows red-hot. The photovoltaic cells which surround the tube receive the infrared (IR) photons from this emitter and convert them to electric power.
