Building a Peltier module
(1/4) > >>
Rachie5272:
Hello, I want to build a Peltier module from scratch.  I have some ideas I want to test out, and there's no better way than prototyping.

Where would I find the raw N and P semiconductor elements to make this from?  I don't even know what they're called, or how to search for them.  Am I better off salvaging them from a cheap module?
ironmonkey:
AFAIK they are two different metal sheets, with no semiconductor involved (kind of a inverse termocouple)

Theoretically this should work, but every explanation of Peltier junctions I've seen says they use semiconductors.  Does anyone know why?
LukeW:
Lots of materials have some Seebeck coefficient (like a thermocouple) but you need a *high* Seebeck coefficient. Doped bismuth telluride is usually the material of choice.

Do you have to use Bismuth metal, or can you use stuff from any WWII wreck?
