Heat-Harvest -Thermoelectric Energy Harvesting (2013-2017)

Project leader: Prof. Maarit Karppinen

Thermoelectric (TE) materials provide us with a highly potential means for sustainable energy exploitation as they are capable of directly converting waste heat into electricity. The proposed project aims at conducting frontier research for

(i) understanding the TE materials from the fundamental materials chemistry point of view and attaining maximal TE performances for currently known and completely new materials. 

(ii) A fundamentally novel TE concept based on ions rather than electrons/holes will be explored.

Within the project TE materials are introduced for a wider community as a potential resource for sustainable energy production by (iii) designing, constructing and optimizing a few model devices such as an efficient microCHP system,

and (iv) identifying the most potential technical solutions of thermoelectrics in Finland.

The goal is that at the end of the project we have been able to find viable material combinations with enhanced TE characteristics to improve energy conversion efficiencies of actual TE modules and devices for a wide range of operation temperatures such that a number of new applications of thermoelectrics could be successfully realized.
