One of the great challenges in perovskite quantum dot light-emitting diodes (Pe-QLEDs) is unbalanced charge injection that significantly hinders device performance and stability. Herein, we tailor-made a high mobility electron-transporting material (ETM), named B2, to balance carrier blue Pe-QLEDs. B2 with tailored asymmetric anthracenyl structure exhibits promising electron 2.7 × 10–4 cm2·V–1·s–1, which almost 20 times higher than commonly used ETM-TPBi (1.1 10–5 cm2·V–1·s–1). Subsequently,...

Abstract A silver‐based organic salt, silver bis(trifluoromethane‐sulfonyl)imide (AgTFSI), was employed as an effective p‐type dopant for the triarylamine‐based hole‐transport material Spiro‐MeOTAD, which has been successfully applied in solid‐state dye‐sensitized solar cells (ssDSCs) and perovskite (PSCs). The power conversion efficiencies (PCEs) of AgTFSI‐doped devices improved by 20 %, compared to device based on commonly used oxygen doping both ssDSCs PSCs. Moreover, exposed AgTFSI...
