SCOPE OF THIS REPORT

This report focuses on sub-watt thermal
energy harvesting: heat is converted
into
electrical
energy
thanks
to
thermoelectric generators delivering up to
500 mW to power low power devices.

It analyzes the offer on: sub-watt Thermo
Electric Generators (TEG) and storage
components industries with a deep
analysis of the technologies, the actors
and a TEG global market quantification.

It investigates the adoption of sub-watt
thermal energy harvesting in 5 main
segments and provides a qualification
and quantification of the 12 most
promising applications.

DEFINITIONS OF THERMO ELECTRIC GENERATOR (TEG)
TECHNOLOGIES
Infinergia has divided thermoelectric technologies into three categories:
1. Bulk TEG technology (a.k.a. 1st generation)

Individually mounted thermoelectric legs, typically ~1 millimeter in size and

Made of Bi2Te3 (Bismuth Telluride) semiconductor materials.

zT is around 0,9 (approximately 8% of thermoelectric efficiency) and generate up to
10s of watts at maximum hot side temperatures around 250°C.
2. Thin-Film TEG or “TF-TEG” technology (a.k.a. 2nd generation)



Bulk TEG

TF-TEG are much smaller and feature orders of magnitude higher thermocouple
density thanks to thermocouple sizes down to a few tens of micrometers.
Output voltage can be a factor of 10 higher per TEG from 1% of TEG volume.
Commercial TF-TEGs also use Bi2Te3
electrochemical or semiconductor processes.
materials
which
undergo
some
3. Emerging thermal energy harvesting technologies (a.k.a. 3rd generation)

3G-TEG technologies are still in development but offer promising levels of
performance (zT of 3 for instance), use of common, abundant materials, or high
temperature operation enabled by new material properties and assembly
technologies.

3G-TEGs leverage both new materials (e.g. SiGe, SiMg) and nanostructures
(nanodots, nanowires or super lattices).

Interesting for high source temperature applications, but yet commercially unproven, is
the Micron-gap Thermo-Photo-Voltaic (MTPV) technology
