Short-Circuit Current
For an ideal solar cell at most moderate resistive loss mechanisms, the short-circuit current and the light-generated current are identical.

The short-circuit current depends on a number of factors which are described below: the area of the solar ...
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.

Quantum Efficiency
The quantum efficiency of a silicon solar cell. Quantum efficiency is usually not measured much below 350 nm as the power from the AM1.5 spectrum contained in such low wavelengths is low. While quantum efficiency ideally has the square shape shown above, the quantum efficiency for most solar cells is reduced due to recombination effects.
Theory of Solar Cells
Another equivalent way to think about the current flow in a photovoltaic cell is that the diode''s natural current flow leeches away some of the current that would normally go to the load. To better understand the behaviour of the photovoltaic cell, it is common to make use of electric circuit analogies in order to understand what''s physically going on.
