In this study, we report to prepare two-dimensional perovskite organometal halide and electron-transporting layer thin films, which are the key layers of solar cell devices by ink-jet printing method. We have developed controllable and optimal inkjet printing process for the growth of perovskite organic metal halide and electron-transporting layer thin films by varying solution properties, printing process parameters (e.g. droplet diameter, voltage, droplet spacing, printing pass), as well as substrate temperature, etc. This demonstration of preparation for organometal halide perovskite and electron-transporting layer films though ink-jet printing offers scope for applying printed electronics technology to manufacture optoelectronic devices.
