Electroluminescence
The key advantage as noted above is the ability of electroluminescence imaging an entire solar cell or module in a relatively short space of time. The light output increases with the local voltage so that regions with poor contact show up as dark.
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.
