3.5.Effect of temperature
At present work study, the temperature of the enhanced device is
different from (300-400k) to know the impact of the temperature on this
device. The results thus obtaiendis shown in figure10.From the results
obtained, we observe that the efficiency of the device gradually
decreases when increasing the temperature. It might be owing to the
point of defect density within the ab layerincreasing the temperature
for that reason the efficiency of the Sn-based material has been
decreased. The observed resultant data are shown in fig.10 as below
