Impacts of Temperature on the Performance of Cdte Based Thin-Film Solar Cell

In this investigation, the effect of temperature on the performance of CdTe based thin film solar cells has been studied. The parameters such as open circuit voltage (Voc), short circuit current density (Jsc), fill factor and efficiency η determines the performance of solar cell. And an important diode parameter, reverse saturation current density, J0 controls the impacts of temperature on the performance parameters. The reverse saturation current density of the CdTe photovoltaic cell, J0 = CT3exp(−qEg/kT) was determinedas optimum for C = 17.90 mAcm−2K3 yields CT3 = 4.74 × 108 mAcm−2. In this case, 298 K is considered to be more suitable temperature to achieve optimized Voc, Jsc, FF, and η calculated for AM1.5G illumination spectra. The maximum attained values of performance parameters are compared with the experimental and theoretical results in the literature of CdTe solar cells. Moreover, the rate of change in performance parameters due to temperature are also measured and compared with the results available in the earlier published works.
