The Effect of Temperature on the Solar Cell Efficiency, Output Currents and Voltages

Experimental results shows that all electrical parameters of solar cell such as maximum output power, open circuit voltage, short circuit current, and fill factor beside efficiency have been changed with temperature. According to results, the most significant is the temperature dependence of the voltage which decreases with increasing temperature while the current of cells slightly increases by temperature. The fill factor and the efficiency decrease upon increasing temperature. This confirms the fact that the voltage decrease is more significant than the current increase.
