Thermoelectric Question

    Just a quick question:

    It is the seebeck effect whereby a directly proportional voltage to the temperature dif is produced. I am wondering whether adding more junctions in that style would produce more electricity.

    Would this....

    produce 3 (three) times more electricity than this...

    ?

    Thank you.

    Adding junctions will only increase the electricity produced if the overall contact resistance goes down. That will increase the amperage but not the voltage. Contact resistance is a significant consideration when designing and producing thermoelectric modules and is typically very, very low so there isn't much to be gained over present art.
