Doped Organic Micro‐Thermoelectric Coolers with Rapid Response Time

Local thermal management has important implications regarding comfort, energy consumption, and electronic device performance/lifetime. While organic thermoelectrics have emerged as promising materials for flexible thermoelectric harvesting devices, their potential Peltier cooling element been largely overlooked. Here, micro-thermoelectric coolers based on doped small molecule thin-films with a fast response time (around 25 µs) which is among the fastest reported are presented. This experimental performance supported by simulation using finite-element method transport. The results show that offer great wearable applications.
