MRS Fall Meeting to Explore the Optimal Structuring of DTP Thermoelectric Material

We're pleased to announce our Chief Technology Officer, Doug Crane, PhD, will be giving an invited talk at the 2022 MRS Fall Meeting in Boston, Massachusetts. The symposium is called "Progress in Thermoelectrics — From Traditional to Novel Materials," and Doug's session will take place on Wednesday, November 30 from 8:15 to 8:45 AM EST at Back Bay A (Sheraton, 2nd floor). Doug will also chair a session later that afternoon at 1:30 p.m. EST.

Maximizing Solid State Heat Pump Performance

During his presentation, Doug will introduce and explore the novel and optimal structuring of spatially distributed transport properties (DTP) within thermoelectric (TE) elements. This structuring, combined with currently available materials, can produce TE systems that increase the single-stage maximum temperature difference (DT) up to 35 percent, coefficient of performance (COP) up to 150 percent and heat pumping capacity up to 200 percent.

According to our numerical modeling, a single-stage DTP thermoelectric device has the potential to reach a maximum DT of 100K based on a hot side temperature of 300K, versus 73K for a standard single-stage TE module operating in cooling mode. One current manufacturer of conventional TE devices manufactures two-stage cascaded devices with a maximum DT that ranges from 86K to 101K. Delivering large performance gains to TE systems, a single-stage DTP device can provide a comparable maximum temperature difference.

Doug will discuss these findings, along with the development of materials specifically optimized for DTP purposes and their projected impact on thermoelectric device performance.

Register for the MRS Fall Meeting

Hosted by the Materials Research Society, the MRS Fall Meeting will take place November 27 to December 2, 2022, at the Hynes Convention Center in Boston, with a virtual version taking place December 6 to 8.
