For a summary of the state of the art in Peltier devices etc see:
ARTI Report No. 10120-01THERMOELECTRIC TECHNOLOGY ASSESSMENT
Final Report May 2007 Dr. Bao Yang
A COP up to 6 or so can be achieved at around room temperature.
Nanostructured materials have been used to reduce thermal conduction
(via phonon scattering) whilst retaining high electrical conduction
(minimal electron scattering).
There are no known theoretical limits to the figure of merit attainable.
However dont expect nanostructured Peltier devices to be readily
available for some time.
