Descripción
Sumario:After establishing themselves as promising active materials in the field of solar cells, halide perovskites are currently being explored for fabrication of low-cost, easily processable, and highly efficient light-emitting diodes (LEDs). Despite this, the highest efficiencies reported for perovskite-based LEDs (PeLEDs) are achieved through spin coating or vacuum evaporation deposition techniques, which are not adequate, in most of the cases, for an industrial-scale production. Additionally, the long-term stability is still a big handicap, even though all inorganic perovskites, such as CsPbBr3, are found to be more stable to external variables. In this context, herein, the fabrication of fully inkjet-printed (IJP) CsPbBr3-based PeLEDs in ambient conditions, on rigid and flexible substrates, on a proof-of-concept basis, with the successful incorporation of NiO and SnO2 as hole- and electron-selective contacts, respectively, is reported. Despite the moderate luminance (324¿cd¿m-2) value obtained, this result paves the way toward the development of upscalable fabrication of PeLEDs based on deposition techniques with controlled spatial resolution.
