Johns Hopkins and Samsung engineers developed a nano-engineered thermoelectric material that is twice as efficient at cooling compared to existing methods. Traditional refrigeration systems use environmentally harmful chemicals and are energy intensive. Thermoelectric cooling, using electric currents in semiconductors, offers an alternative but has limitations. The researchers' thin-film materials provide a substantial improvement in performance at room temperature and are ready for mainstream refrigeration applications. This technology, known as CHESS, was initially developed for national security and has potential uses across various sectors.
This research shows that the CHESS technology, which provides a significant boost in thermoelectric performance, could transform conventional refrigeration and air conditioning systems.
Researchers found that their nano-engineered thin-film materials can achieve cooling capabilities almost doubled compared to existing bulk methods, making them suitable for more widespread use.
