Electron transport layer ink and manufacturing method and application thereof

The invention discloses electron transport layer ink. The electron transport layer ink is formed by mixing an organic electron transport material and an organic solvent capable of dissolving the organic electron transport material. The invention further discloses a manufacturing method of the electron transport layer ink and application of the electron transport layer ink. The invention provides electron transport layer ink suitable for ink-jet printing and a manufacturing method thereof. Furthermore, in the electron transport layer ink disclosed by the invention, the prepared electron transport layer ink is enabled to have relatively good viscosity, surface tension and stability by adopting the single-component solvent. Furthermore, when the electron transport layer ink is used for manufacturing an electron transport layer, the annealing process is easy to regulate and control, and the film forming uniformity is good. 本发明公开了一种电子传输层墨水。所述电子传输层墨水由有机电子传输材料以及能够溶解所述有机电子传输材料的有机溶剂混合形成。本发明还公开了一种该电子传输层墨水的制作方法以及该电子传输层墨
