July 23, 2008--Nextreme Thermal Solutions (Durham, NC), provider of microscale thermal and power management products, was awarded a grant from the North Carolina Green Business Fund to enhance the efficiency of its thin-film thermoelectrics that convert waste heat into electricity. Nextreme's technology can be incorporated into tiny laser diode and optoelectronic components, unlike standard and bulkier thermoelectric cooler technologies.
Nextreme's thin-film embedded thermoelectric generator (eTEG) generates electricity via the Seebeck effect, where electricity is produced from a temperature differential applied across the device. The Nextreme advantage is a very thin, nano-engineered material that delivers a Seebeck coefficient 150% greater than conventional thermoelectric material. The grant from the North Carolina Green Business Fund will be used to optimize the Nextreme thin-film growth process with the goal of doubling the power output of a single device from 250 mW to 500 mW.
"We are already demonstrating our devices in a number of specialty applications where heat is available and power is required," said Nextreme CEO Jesko von Windheim. "Increasing Nextreme's power conversion efficiency will open up a whole new scale of market opportunities." Nextreme announced back in June that it was jointly developing a short-wave infrared (SWIR) focal plane sensor using extremely efficient thermoelectric cooling with Princeton Lightwave (Cranbury, NJ).
