Interesting application…one thing to keep in mind is that thermocouples are very inefficient and require a large temperature difference.
That being said, this technology should definitely be pursued.
Ashraf…I’m pretty sure they don’t work by expansion and contraction…

could cheap, thin thermoelectric membrane be placed on the backside of PV to absorb/convert the heat to electricity? Probably temps are too low/not enough difference in temp to outside air to capture enough energy to be worth it.

Great,this innovation is great, as a renewable source of energy,no emission ,no noise,when i read about it i remembered the thermo couple when two different metals expose to same temperature ,and expand due to their expand coefficient ,to generate electric signals .to measure a high temperatures.
