At higher light intensities (25% sun), however, the cell has lower efficiency (around 0.8%), governed by both series and shunt resistance. An initial decrease in the fill factor with the light intensity decrease is not sufficient to cause reduction in the cell efficiency, due to slight variations in voltage and current.
Effect of Light Intensity
Changing the light intensity incident on a solar cell changes all solar cell parameters, including the short-circuit current, the open-circuit voltage, the FF, the efficiency and the impact of series and shunt resistances.The light intensity on a solar cell is called the number of suns, where 1 sun corresponds to standard illumination at AM1.5, or 1 kW/m 2.
