A team of engineers and materials scientists from the Paul M. Rady Department of Mechanical Engineering at the University of Colorado<\/strong> at Boulder has developed a technology that can convert waste heat into electricity.<\/p>\n\n

The development of a thermophotovoltaic technology<\/h2>\n\n

This development is led by Associate Professor Longji Cui, the Cui Research Group collaborated with researchers from the National Renewable Energy Laboratory<\/strong> ( NREL<\/em> ) and the University of Wisconsin-Madison<\/strong> to carry out this project, the results of which have recently been published in the journal Energy & Environmental Sciences<\/strong> .<\/p>\n\n

Heat is an often overlooked renewable energy source. Two-thirds of all the energy we use is converted to heat. We can recover some of this wasted thermal energy and use it to produce clean electricity. <\/p>\nProfessor Cui said.<\/cite><\/blockquote>\n\n

Cui and his team have accomplished a feat by designing a thermophotovoltaic<\/a><\/strong> ( TPV<\/em> ) device that can double the power density achieved with conventional TPV designs. This compact device defies Planck\u2019s Law of Thermal Radiation<\/strong> and promises to increase power generation without the need for high-temperature heat sources or expensive materials. <\/p>\n\n

Cui\u2019s group has designed a unique TPV device that employs a \u201c zero vacuum gap<\/em> \u201d solution with an insulated spacer made of high-index, infrared-transparent glass. This allows thermal heat waves to travel through the device without losing strength, dramatically improving power generation. <\/p>\n\n

When we were exploring this technology, we had theoretically anticipated a high level of improvement, but we weren’t sure what it would look like in a real-world experiment. After running the experiment and processing the data, we saw the improvement ourselves and knew it was a great thing. <\/p>\nMohammad Habibi, a PhD student in Cui\u2019s lab.<\/cite><\/blockquote>\n\n

A device that can convert waste heat into electricity<\/h2>\n\n

The low-temperature zero-vacuum solution opens up new possibilities for power generation in industrial processes, such as glass, steel and cement production. ” Our device can recover wasted heat and provide the energy storage they need with a low working temperature<\/em> ,” Cui said.<\/p>\n\n

The team plans to continue exploring alternative materials to further improve the power density of the TPV device. \u201c This is the first demonstration of this new TPV concept<\/em> ,\u201d Habibi explained. \u201c But if we use other cheap materials with similar properties, such as amorphous silicon, we could increase the power density by up to 20 times<\/em> .\u201d<\/p>\n\n
