Inorganic-organic hybrid perovskite solar cells (PeSCs) have recently emerged as a highly promising and inexpensive solution for sustainable energy. Low cost and solution processed PeSCs have shown great potential for scaling-up mass production, researches for printable PeSCs such as slot-die and blade coating have been increasing rapidly. Herein, we report solvent engineering for slot-die coating in an ambient condition. Various solvents were compared to find a suitable solvent for slot-die coating. The electrical, structural, and optical properties of the perovskite layer made by slot-die coating were investigated. In addition, photovoltaic performances of the perovskite solar cells were observed by AM 1.5G one sun solar simulator. |
