This figure illustrates Seebeck coefficient (S) varying with position in a thermoelectric (TE) cooling couple
consisting of N and P type elements. Toward the hot end, the spatially varying Seebeck coefficient in the
N type TE material is progressively more negative, while the coefficient in the P type material is progressively
more positive. (Image: DTP Thermoelectrics)
Adjusting these transport properties
to achieve ideal cooling, heating and
temperature control, unlocks new applications
that were not previously possible
in solid state.
With the emergence of advanced
manufacturing processes like spark plasma
sintering, ion implantation and
additive manufacturing, production of
DTP thermoelectric materials has now
been enabled at a cost-effective price
point to solve real-world challenges.

Thermal Benefits
The maximum achievable ΔT of a
standard TE module in cooling mode is
73 °C when based on a hot-side temperature
of 27 °C. To increase the ΔT, additional
stages must be added to the device,
driving up costs and design complexity,
as well as reducing cooling capacity due
to the additional interfacial resistances.
A DTP module can reach beyond standard
ΔT markers without the need for
these multiple stages.
