The Influence of Temperature on the Electric Parameters of a Solar Cell Based on Cu(In,Ga)Se2

We used the simulation program Solar Cell Capacitance Sumilator in 1 Dimension (SCAPS-1D) to study the influence of temperature on the electrical parameters of a solar cell based of heterojunction CIGS/CdS/ZnO under constant illumination (1000W/m?) under the conditions AM1.5G. The parameters studied are the short circuit current density(JSC), the open circuit voltage (Voc), the form factor (FF), the efficiency of the cell (?) and the external quantum efficiency (QE) in the range of 273K to 333 K. The simulation shows that the JSC increases while the Voc decreases as a function of temperature. The increase in Jsc causes significant external quantum efficiency and the reduction of Voc and the maximum power affects the FF thus decreasing the efficiency of the solar cell.
