THE EFFECT OF TEMPERATURE VARIATIONS ON SOLAR CELL EFFICIENCY

In this work, the influences of temperature variations on the different solar cell parameters are studied. It isuseful to understand the effect of temperature on the solar cell and module performance, in order to estimatetheir performance under various conditions. The short circuit current Isc increases so monotonous withtemperature and then saturates to a maximum value before decreasing at high temperatures. The opencircuit voltage Voc increases linearly with temperature. The fill factor and efficiency, which are directlyrelated with Isc and Voc follow the variations of the letters. The phenomenon is explained by the behaviourof the mobility which is a temperature activated process. The maximum efficiency of (27%) is obtained inwhich Isc= 92 mA and Voc= 147 mV.
