However, the efficiency of these cells is greatly influenced by their configuration and temperature. This research aims to explore the current–voltage (I−V) characteristics of individual, series, and parallel configurations in crystalline silicon solar cells under varying temperatures.
For crystalline silicon solar cells this temperature is 270 o C, Evans and Florschuetz . In a number of correlations, the cell/module temperature which is not readily available has been replaced by T NOCT , i.e., by the nominal operating cell temperature.
Conclusion In this work, an experimental study has been carried out that investigates the effect of temperature on the characterisation parameters of a crystalline silicon solar cell. Current–voltage data from a cell was collected at ten discrete temperatures using a precise source measuring unit while illuminated at constant irradiance.
The actual value of the temperature coefficient, in particular, depends not only on the PV material but on T ref , as well. It is given by the ratio 1 ref oref TT (4) in which T o is the (high) temperature at , Garg and Agarwal . For crystalline silicon solar cells this temperature is 270 o C, Evans and Florschuetz .
The effect of temperature on photovoltaic operation The influence of temperature on the performance of a crystalline silicon cell is chiefly attributed to the temperature dependence of the material’s band gap (Eg) which decreases with temperature, and the minority-carrier lifetime which increases with temperature ( Radziemska, 2003 ).
In this paper, a brief discussion is presented regarding the operating temperature of one-sun commercial grade silicon- based solar cells/modules and its effect upon the electrical performance of photovoltaic installations. Generally, the performance ratio decreases with latitude because of temperature.
