ABSTRACT = {A novel roof tile thermoelectric generator (RT-TEG) was used to harvest electrical energy from a solar heat
source. The RT-TEG was fabricated and simulated by flat and curved thermoelectric modules consisting of
p-n junctions of <i>p</i>-Sb<sub>2</sub>Te<sub>3</sub> and <i>n</i>-Bi<sub>2</sub>Te<sub>3</sub>, with an Al<sub>2</sub>O<sub>3</sub> substrate at the top and bottom for heat absorption
and heat rejection. The RT-TEG was installed in a roof tile to act as a generator. The electrical voltage and power
values of the curved thermoelectric modules were higher than those of the flat thermoelectric module by 0.44 V
and 80 mW, at a temperature difference (ΔT) of 100 K. In field tests, the RT-TEG produced a maximum electrical
voltage of 33.70 mV and an electrical power of 46.24 μW at ΔT~7 K under a load resistance of 1 Ω under good
sunshine at 13.00 hours. The energy conversion efficiency of RT-TEG was found to be 2.24 × 10<sup>−4</sup>.},
