- Abstract
- Recently, there has been rapid development of technologies for creating flexible and stretchable optoelectronic devices. A promising material in terms of fundamental properties is the inorganic halide perovskite CsPbBr, whose electroluminescence brightness can reach 45.000 cd/m. However, the most common thin-film technology of perovskite-based devices cannot solve a number of significant problems: ensuring the stability of the perovskite to the environment, creating tensile-resistant contacts, ensuring efficient injection of carriers into the electroluminescent layer, etc. To solve these problems, the authors developed a new device architecture based on a distributed electrode, which uses an array of whisker nanocrystals embedded in the light-emitting layer, thus solving the fundamental problem of the short lifetime of CsPbBr carriers. The device is enclosed in a special silicone polymer - a transparent inert flexible and stretchable matrix that protects the CsPbBr perovskite from environmental conditions and maintains the orientation of the arrays of whisker nanocrystals. 90% transparent single-walled carbon nanotubes, which have a high tensile strength and low electrical resistance, were used as an electrode providing lateral transport of carriers. Thus, a flexible device with high electroluminescence efficiency was obtained.
