The thin-film Peltier cooling technology cools without chemicals, works faster, and can be made for use in many products.
Samsung Electronics with the Johns Hopkins Applied Physics Laboratory (APL) have presented advancements in next-generation Peltier cooling technology. Peltier devices cool by leveraging the Peltier effect, where applying an electric current to a semiconductor causes one side to cool while the opposite side heats up. Because this method does not rely on refrigerants, it is emerging as a promising, environmentally friendly alternative to traditional cooling systems.
By utilizing newly developed thin-film Peltier semiconductor devices enhanced through advanced nano-engineering techniques for the first time, the research team has successfully created and demonstrated a high-performance Peltier refrigerator.
This thin-film Peltier refrigerator exceeds the cooling efficiency of conventional vapor compression systems, paving the way for the commercialization of next-generation refrigerators that operate without refrigerants.
Compared to traditional vapor compression technology, Peltier cooling offers faster and more precise temperature control with a simpler design, making it suitable for a wide range of industries, including home appliances, semiconductors, medical devices, automotive electronics, and data centers.
Achieving superior cooling efficiency in Peltier semiconductor devices is crucial for the commercialization of high-performance Peltier cooling technology.
Samsung and the APL research team accomplished this by boosting the efficiency of Peltier devices by nearly 75%, through the introduction of new thin-film semiconductor materials combined with miniaturization and lightweight design.
The newly developed Peltier device also offers notable benefits in resource efficiency and manufacturability. The team confirmed that the innovative manufacturing process drastically reduced the amount of Peltier material needed to approximately 1/1,000 of the typical volume, while also streamlining production steps. This breakthrough improves scalability and supports mass production, promising substantial advancements in both cost-effectiveness and environmental sustainability.
Good but details of materials are not given.
AS far as I know, Bismuth Telluride is the best thermo electric material. Using this, in America, Refrigerators and air conditioner units are available.
To discover new materials, the scientists use entropy calculations of elements an compounds and theoretically discover new materials. Then those materials are fabricated and tested. Good materials can be discovered.
