Staying cool without refrigerants: Next-generation Peltier cooling

On June 28, Samsung Electronics, together with the Johns Hopkins University Applied Physics Laboratory (APL), published a paper on next-generation Peltier cooling technology in the prestigious scientific journal Nature Communications. During the process of applying the nano-thin-film Peltier devices — structured differently compared to conventional ones — directly to refrigerators, challenges such as increased contact thermal resistance, which hindered heat transfer, or unstable performance arose. As a result, the refrigerator reduced power consumption by as much as 30% compared to the top grade of Korea’s energy efficiency rating labeling system, 1 while also significantly improving its ability to maintain a stable internal temperature.
