The I–V curve of a solar cell represents the relationship between the current and voltage output of the solar cell under various conditions of illumination and temperature. It is a graph that plots the current produced by the solar cell against the voltage applied to the cell. The I–V curve of a Si solar cell is shown in Fig. 8.5.
The spectral response curve of a typical Si solar cell is shown in Fig. 8.4. The spectral response at the intermediate wavelengths is similar to an ideal solar cell. However, below 400 nm, the spectral response is low due to maximum light absorption by glass.
Generally, I–V curves are given preference when measuring the performance of solar cells and less emphasis is given to spectral response, internal quantum efficiency (IQE), and external quantum efficiency (EQE) quantum.
IV curves provide information on the solar cell's maximum power output, open-circuit voltage, short-circuit current, and fill factor. EQE measurements reveal the solar cell's spectral response and its ability to convert photons into electrons. CV curves provide information on the solar cell’s doping concentration and depletion region width.
The shape of the I–V curve depends on the efficiency, material, and operating conditions of a solar cell. At zero voltage, the current through the solar cell is zero, as there is no external load. The current produced by a solar cell increases with an increase in the voltage across the solar cell.
