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.
Example — Module Open-Circuit Voltage. A PV module, or a string of series-connected modules, has a rated open-circuit voltage that is measured (and labeled on the module) at an irradiance of 1000 W/m 2 and a cell temperature of 25°C (77°F). This voltage increases from the rated voltage as the temperature drops below 25°C.

Temperature has an impact on all solar cell module parameters, such as short-circuit current (I sc), open-circuit voltage (V oc), efficiency, and many others [13, 14]. Different from irradiance, I sc and V oc increase when irradiance increases, where temperature has the opposite concept because it is a function of irradiance.

The IV curve of a solar cell is the superposition of the IV curve of the solar cell diode in the dark with the light-generated current.1 The light has the effect of shifting the IV curve down into the fourth quadrant where power can be extracted from the diode.
