Core–shell carbon-polymer quantum dot passivation for near infrared perovskite light emitting diodes
Abstract
<jats:title>Abstract</jats:title><jats:p>High-performance perovskite light-emitting diodes (PeLEDs) require a high quality perovskite emitter and appropriate charge transport layers to facilitate charge injection and transport within the device. Solution-processed n-type metal oxides represent a judicious choice for the electron transport layer (ETL); however, they do not always present surface properties and energetics compatible with the perovskite emitter. Moreover, the emitter itself exhibits poor nanomorphology and defect traps that compromise the device performance. Here, we modulate the surface properties and interface energetics between the tin oxide (SnO<jats:sub>2</jats:sub>) ETL with the perovskite emitter by using an amino functionalized difluoro{2-[1-(3,5-dimethyl-2<jats:italic>H</jats:italic>-pyrrol-2-ylidene-<jats:italic>N</jats:italic>)ethyl]-3,5-dimethyl-1<jats:italic>H</jats:italic>-pyrrolato-<jats:italic>N</jats:italic>}boron compound and passivate the defects present in the perovskite matrix with carbon-polymer core–shell quantum dots inserted into the perovskite precursor. Both these approaches synergistically improve the perovskite layer nanomorphology and enhance the radiative recombination. These properties resulted in the fabrication of near-infrared PeLEDs based on formamidinium lead iodide (FAPbI<jats:sub>3</jats:sub>) with a high radiance of 92 W sr<jats:sup>−1</jats:sup> m<jats:sup>−2</jats:sup>, an external quantum efficiency (EQE) of 14%, reduced efficiency roll-off and prolonged lifetime. In particular, the modified device retained 80% of the initial EQE (T<jats:sub>80</jats:sub>) for 33 h compared to 6 h of the reference cell.</jats:p>
