Dark current is the small electric current that flows through a solar cell even in the absence of light, reducing its efficiency. Dark current is one of the main sources of noise in image sensors and can lower the open-circuit voltage and fill factor of solar cells.
A decrease in ideality factor of GaAs solar cells due to irradiation with 1MeV electron radiation resulted in decreased open circuit voltage and maximum power. Dark current-voltage measurements suggest that 1 MeV electron radiation primarily affects dark current produced at voltages greater than 0.5 V. The dark saturation current of irradiated solar cells increased but
