Low-Cost High-Reliability Thermoelectrics for Waste Heat Conversion

Low-Cost High-Reliability Thermoelectrics for Waste Heat Conversion

This project consists of paper study and laboratory research to develop techniques for creating cost-effective thermoelectric generators using silicone nanowire arrays. Small-scale fabrication processes, including precision doping and etching techniques commonly used for manufacturing integrated circuits, will be employed in a laboratory setting to make individual nanowires and free-standing nanowire arrays which will be tested to measure their mechanical and thermoelectric performance. Fabrication will take place in Alphabet Energy's 8000 sq. ft. laboratory/manufacturing facility in Hayward, CA. Bench-scale testing of physical and thermoelectric properties of test specimens will occur at the Lawrence Berkeley National Laboratory. Minor bench-scale equipment will be procured and integrated into the LBL laboratory to facilitate testing. Paper study research and report writing will occur at both sites. By increasing the temperature range and lowering the cost of thermoelectric heat recovery system, CA ratepayers will benefit by the reduced electricity usage in the industrial and retail sectors, increasing electrical reliability and lowering electricity costs.
