Semiconductor Thermoradiative Power Conversion
Abstract
The thermoradiative diode is a new optoelectronic device that enables electrical power generated from warm surfaces radiating into a cold ambient. The first practical demonstration of power from a thermoradiative device was achieved by UNSW Sydney, confirming the practical viability for this new source of electrical power from radiant heat. However, to make a meaningful contribution towards the electrical power supply, two key aspects of the technology to be improved- Firstly the power density must be increased to the level of W.m-2 and the secondly device area must be scaled to devices similar in size to solar PV cells. Both tasks are tackled in this project - New thermoradiative deviceswill be designed using models developed at UNSW and also fabricated at UNSW. Nanophotonic structures will be fabricated on these diodes at Monash University to ensure efficient outcoupling of infrared light over large areas. The project will provide a clearer perspective of the viability of space applications by fabricating proof-of-concept thermoradiative diodes using III-V semiconductor diode devices and a nanophotonic front surface structure.
