Original abstract
High Resolution Image Download MS PowerPoint Slide Inkjet printing (IJP) is a promising technique for achieving uniform, large-area deposition of perovskite films. Although IJP offers several advantages in processability and scalability that are highly attractive for industrial manufacturing, systematic studies employing in-line controlled inkjet printing systems remain scarce. Here, we demonstrate the deposition of approximately 700 nm-thick perovskite films by IJP at a relative humidity (RH) of 55% in an air atmosphere. We found that the quenching pathway of the wet perovskite film strongly influences the resulting film morphology and crystallographic characteristics. By optimizing this process, we successfully fabricated self-assembled monolayer-incorporated wide-bandgap perovskite films with a dominant (110) crystallographic orientation using IJP. As a result, we achieved over 20% efficiency in a 1.69 eV bandgap perovskite solar cell, which is suitable for silicon−perovskite tandem integration.
