This paper investigates, theoretically, the temperature dependence of the performance of solar cells in the temperature range 273–523 K. The solar cell performance is determined by its parameters, viz., short circuit current density (J_sc), open circuit voltage (V_oc), fill factor (FF) and efficiency (η). Solar cells based on semiconductor materials such as Ge, Si, GaAs, InP, CdTe and CdS are considered here. Reverse saturation current density (J_o) is an important diode parameter which controls the change in performance parameters with temperature. In this work, reverse saturation current density (J_o=C.T³.exp (−qE_g/kT)) is determined for three cases. Cases (I) and (II) correspond to C=17.90 and 50 mA cm⁻² K³ respectively, whereas, case (III) corresponds to C.T³=A=1.5×10⁸ mA cm⁻². The maximum achievable V_oc, J_sc, FF and η of solar cells are calculated for AM1.5G and AM0 spectra and are compared with …
