shows the comparison between the calculated PV temperature profiles and the experimental PV temperature
data of the Huang’s PV–PCM system [14]. One can find that the simulated data coincide well with the experimental data.
The mean deviation between the simulated data and the experimental data is 7%. Fig. 4(b) is the comparison between the calculated efficiencies of a TE generator and the Al-Nimr’s results [5]. The calculated efficiencies by the present model are somewhat higher than the Al-Nimr’s results [5], which is because that heat
