Thermoelectric Question

  1. Apr 24, 2009 #1
    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.

    how is that? are they viewable now?

    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.
