摘要

金属卤化物钙钛矿发光二极管（Perovskite light⁃emitting diodes， Pero⁃LEDs）器件结构中，空穴传输层（HTL）是影响Pero⁃LEDs效率的关键性因素之一。由于醋酸钴（Co（OAc）

）薄膜具有优异的光电特性，所以选其作为绿光Pero⁃LEDs的HTL。然而，纯的钴基底薄膜存在传输载流子能力较差、薄膜粗糙度较大等问题。因此，本文通过引入有机小分子添加剂乙醇胺（ETA）来有效调控传输层中Co

/Co

比例，提升传输层的导电能力。同时，因ETA的加入可以减缓退火过程中前驱体溶液的析出结晶速度，从而形成粗糙度较小的HTL薄膜，进而有利于形成高质量的钙钛矿薄膜。基于掺杂的HTL，其最优器件亮度高达45 207 cd/m

，最大外量子效率（EQE）达到15.08%，是一种性能较好的新型HTL。

Abstract

In the device structure of metal halide perovskite light-emitting diodes （Pero-LEDs）， the hole transport layer （HTL） is one of the critical factors affecting the efficiency of Pero-LEDs. Because cobalt acetate （Co（OAc）

） film has excellent photoelectric properties， it has been selected as the HTL for green Pero-LEDs. However， the pure cobalt-based HTL films have problems such as poor carrier transport ability and large film roughness. Therefore， in this paper， by introducing the organic small molecule additive ethanolamine （ETA）， the proportion of Co

/Co

in the transport layer is effectively regulated， and the conductivity of the transport layer is improved. At the same time， the addition of ETA can slow down the crystallization process of HTL precursor solution during the annealing process， bringing in a transport layer film with lower roughness， which is conducive to the deposition of high-quality perovskite films. Based on the doped Co-based HTL films， the optimal device brightness reaches 45 207 cd/m

， and the maximum external quantum efficiency （EQE） reaches 15.08%， proving that the Co-based compound is a novel HTL with good device performance.
