APL's Scalable Thin-Film Refrigeration Tech: CHESS
2025-07-03
APL has developed CHESS, a thin-film thermoelectric material, revolutionizing refrigeration. Using only 0.003 cubic centimeters—about the size of a grain of sand—per unit, CHESS leverages established MOCVD manufacturing for scalability and cost-effectiveness. Its potential extends beyond small-scale refrigeration to large-scale HVAC systems, mirroring the scalability of lithium-ion batteries. Furthermore, CHESS can convert temperature differences into usable energy, opening doors for energy harvesting in various applications, from computers to spacecraft. This breakthrough signifies the viability and scalability of high-efficiency solid-state refrigeration.
