Samsung Electronics, in collaboration with the Johns Hopkins Applied Physics Laboratory (APL), published a research paper titled “Nano-Engineered Thin-Film Thermoelectric Materials Enable Practical Solid-State Refrigeration” in Nature Communications. The paper outlines the development of a next-generation Peltier cooling technology.
Peltier devices use the Peltier effect, where an electric current applied to a semiconductor cools one side and heats the other, requiring no refrigerants. The technology was developed by Samsung Research’s Life Solution Team and Dr. Rama Venkatasubramanian’s thermoelectrics research team at APL.
The research team created a Peltier refrigerator using thin-film semiconductor devices with nano-engineering technology. This refrigerator achieves higher cooling efficiency than traditional vapor compression systems and supports applications in home appliances, semiconductors, medical devices, automotive electronics, and data centers. The Peltier method allows faster and more precise temperature control with a simpler configuration compared to vapor compression methods.
The new Peltier device improves efficiency by nearly 75% through thin-film semiconductor materials, miniaturization, and lightweight design. The manufacturing process reduces Peltier material usage to approximately 1/1,000 of typical requirements and simplifies production steps, enhancing scalability and mass production potential while reducing costs and environmental impact.
