Electrocooling can be achieved by the Peltier effect with appropriate materials.Using poly(Ni-ett) thin-film devices, a temperature difference of > 40 degrees Celsius was achieved, allowing for electrocooling of organic thermoelectric devices. It is predicted that ultra-thin devices of this type of material can achieve large temperature difference electrocooling with a heat flux density exceeding 500 W cm-2 in flexible solid-state refrigeration.
