Researchers have unveiled a breakthrough in solid-state cooling technology, doubling the efficiency of today's commercial systems. Driven by the Lab's patented nano-engineered thin-film thermoelectric materials and devices, this innovation paves the way for compact, reliable and scalable cooling solutions that could potentially replace traditional compressors across a range of industries.
"This real-world demonstration of refrigeration using new thermoelectric materials showcases the capabilities of nano-engineered CHESS thin films," said Rama Venkatasubramanian, principal investigator of the joint project and chief technologist for thermoelectrics at APL."It marks a significant leap in cooling technology and sets the stage for translating advances in thermoelectric materials into practical, large-scale, energy-efficient refrigeration applications.
The results were striking: Using CHESS materials, the APL team achieved nearly 100% improvement in efficiency over traditional thermoelectric materials at room temperature .
"We used metal-organic chemical vapor deposition to produce the CHESS materials, a method well known for its scalability, cost-effectiveness and ability to support large-volume manufacturing," said Jon Pierce, a senior research engineer who leads the MOCVD growth capability at APL."MOCVD is already widely used commercially, making it ideal for scaling up CHESS thin-film thermoelectric materials production.
"The success of this collaborative effort demonstrates that high-efficiency solid-state refrigeration is not only scientifically viable but manufacturable at scale," said Susan Ehrlich, an APL technology commercialization manager."We're looking forward to continued research and technology transfer opportunities with companies as we work toward translating these innovations into practical, real-world applications.
