Fig. 2

(A) Schematics of the microstructures of pristine HTL and is-HTL designed in this study. (B) Raman spectra of pristine AI 4083, is-HTL with various wt % of Triton X, and a glass substrate. (C) Mechanical properties of pristine HTL and is-HTL thin films. The conformation of the PEDOT chains is changed from coiled to linear with the addition of Triton X, which results in improved electrical and mechanical properties of is-HTL. (D) Luminance (L)–V plot of OLEDs with the solution-processed is-ETL and is-cathode with a discrete layer and a composite-like structure.
