The invention discloses a preparation method of a perovskite solar cell based on an ionic liquid additive. The perovskite solar cell based on the ionic liquid additive comprises a top electrode, a hole transport layer, a perovskite absorption layer, an electron transport layer, a transparent conductive substrate and a bottom electrode; between the top electrode and the transparent conductive substrate A top-to-bottom hole transport layer, a perovskite absorption layer, and an electron transport layer are provided, or a top-to-bottom electron transport layer, a perovskite absorption layer, and a hole are provided between the top electrode and the transparent conductive substrate. A hole transport layer; a bottom electrode is also arranged on the transparent conductive substrate. The invention has the advantages of simple and easy operation, low cost, low toxicity hazard in the preparation process, controllable crystallization and high film quality, and provides a new idea for the preparation of high-efficiency and large-area perovskite batteries. |
