Abstract
Methods, ink compositions, and 3D conformal printed flexible films. The method may include aerosol jet printing a thermoelectric ink composition, followed by photonic or other sintering of the ink to remove surfactant included therein, and to convert the thermoelectric nanoparticles of the ink composition into a dense structure capable of charge carrier transport. The ink compositions may be solution-processed semimetal-chalcogenides (e.g., Te containing materials) in a suitable carrier (e.g., polyol(s), alcohol(s), etc.). A surfactant (e.g., PVP) may be present in the ink. Within seconds of photonic sintering, the electrical conductivity of the printed film is dramatically increased from non-conductive to a value on the order of at least 1×10S/m. The films may demonstrate a room-temperature power factor of at least 500 μWmK. The realized values of 730-2200 μWmKachieved are among the highest values reported for flexible thermoelectric films. The film is durable (e.g., 500 bending cycles with no significant performance drop).
