Optical and transport properties of mixed halide all-inorganic quantum dot inkjet-printed films

ORAL

Abstract

Inorganic halide perovskite quantum dot inks may have great potential in applications related to the field of inkjet-printed photovoltaics. The photoactive inks are synthesized by a wet chemical reaction and are printed into thin films using a commercial inkjet printer. The inkjet-printed films were then characterized using optical absorption spectroscopy, photoluminescent spectroscopy, X-ray diffraction, X-ray photoemission spectroscopy, and electronic transport measurements. Characterization indicates that interlayer printing, alternating printed layers of CsPbBr3 and CsPbI3 , results in a halide exchange producing a high quality (220) CsPbBr2.1I0.9 quantum dot thin film. The repeatable properties of the inkjet-printed thin films suggest high quality, customizable, photovoltaic films are realizable with an inkjet printing method.
