Powered by windows: enhanced power factor in transparent thermoelectric nanowire materials

(Osaka University) A research group led by Professor Yoshiaki Nakamura of Osaka University successfully developed a methodology for enhancing thermoelectric power factor while decreasing thermal conductivity. By introducing ZnO nanowires into ZnO films, the thermoelectric power factor became 3 times larger than that of ZnO film without ZnO nanowires. The success of this research will lead to the realization of high-performance transparent thermoelectric devices which will enable energy recovery from transparent objects used all over the world.
