QUT Develops High-Efficiency Thermoelectric Material

Queensland University of Technology (QUT) researchers developed a material that significantly improves waste heat conversion into electricity. The team's advance addresses energy loss from vehicles, industry, and power generation. Published August 28, 2025, in *Energy & Environmental Science*, the research details a silver copper telluride compound enhanced with manganese. This material achieves over 13 percent efficiency in converting heat to electricity. Traditional materials typically convert a smaller fraction. Led by Professor Zhi-Gang Chen and Dr. Xiao-Lei Shi, the QUT team created a non-toxic, scalable material. The new compound avoids hazardous elements, unlike some existing thermoelectric options. Potential applications include enhanced energy recovery in automotive and manufacturing sectors. Professor Chen notes the vast amounts of heat wasted daily from common sources. The improved efficiency could substantially reduce energy waste. The team anticipates the material will contribute to global carbon neutrality goals. Further research will focus on optimizing the material for specific industrial applications and scaling up production for commercial use. The development represents a step toward more efficient energy use and reduced reliance on fossil fuels.
