  • Single-Layer Light-Emitting Diodes Using Organometallic Halide Perovskite/Ionic-Conducting Polymer Composite
    Publication number: 20210151704
    Abstract: Single-layer LEDs were developed using a composite thin film of organometal halide perovskite (Pero) and poly (ethylene oxide) (PEO). Single-layer Pero LEDs have a device structure that resembles “bottom electrode (ITO)/Pero-PEO/top electrode (In/Ga or Au)”. Green emission LEDs with methylammonium lead bromide (bromide-Pero) and PEO composite thin films exhibit a low turn-on voltage of about 2.8-3.1V (defined at 1 cd m?2 luminance), a maximum luminance of 4064 cd m?2 and a moderate maximum current efficiency of about 0.24-0.74 cd A?1. Blue and red emission LEDs have also been fabricated using Cl/Br or Br/I alloyed Pero-PEO composite thin films.

  • Printed halide perovskite light-emitting diodes and method of manufacture
    Patent number: 10547011
    Abstract: Printed poly(ethylene oxide) (PEO) organometallic halide Perovskite (Pero) optoelectronic devices, including light emitting diodes (LEDs) fabricated on both rigid indium tin oxide (ITO)/glass and flexible carbon nanotube (CNTs)/polymer substrates using a composite thin film of PEO and Br-Pero as the light-emitting layer. Method of manufacturing Printed poly(ethylene oxide) (PEO) organometallic halide Perovskite (Pero) optoelectronic devices performed in an environment at a temperature of about 25° C. and a relative humidity between about 70% and 80%.
