Summary: The fabrication of perovskite solar cells through blade coating often leads to more defective films. In this study, a bifunctional molecule, p-aminobenzoic acid (PABA), was used to enhance the barrier to ion migration and promote the formation of defect-reduced, homogeneous films. The PSCs with PABA achieved impressive power conversion efficiencies and maintained high stability under extreme conditions.

Summary: A vacuum-assisted approach is developed to fabricate mirror-like, pinhole-free, highly crystalline, and uniform blade-coated perovskite films without using antisolvent and air knife. The effect of phenethylammonium iodide passivation at the top and bottom interfaces of a perovskite layer based on an FTO/NiOx/perovskite/C-60/BCP/Cu inverted p-i-n structure is systematically investigated. The encapsulated device, fabricated by blade coating under ambient conditions, retains 97% of its maximum efficiency after a 1000-hour photostability test.

Summary: Organic-inorganic hybrid perovskite solar cells (PSCs) show great potential in industrial commercialization, but efficiency and stability decrease when scaling up the device area. Blade-coating methods have been developed to fabricate large-area PSCs with uniform perovskite films. Ink engineering plays an important role in blade-coating, especially for crystallinity and defect control. This review summarizes the blade-coating method for large-area perovskite films, perovskite ink engineering, and recent advances in functional layer ink engineering and hole transporting material-free carbon-based PSCs.

Summary: This study explores the packing-shape effects of amplified spontaneous emission (ASE) through orbital polarization dynamics between light-emitting excitons by stacking perovskite quantum dots of different shapes. The rod-like packing demonstrates a longer photoluminescence lifetime and a red-shifted peak compared to the diamond-like packing, indicating stronger interactions and surface-to-inside property-tuning capability. Additionally, the ASE enabled by the rod-like packing shows orbit-orbit polarization interaction between light-emitting excitons under linearly/circularly polarized pumping conditions.

Summary: Polyacrylic acid complexed with polyaniline (PAA/PANI) composite materials have the potential to form organic mixed ion-electron conductive (OMIEC) films, which can be used in optoelectronic and energy storage applications. The composite films are formed through an acid-base reaction, resulting in strong electrostatic interactions and intermolecular hydrogen bonds between PANI and PAA. The separation of PANI-rich domains from PAA-rich matrix in the composite films is observed. The electrical conductivity of the composite films is higher when the content of PANI is 33 wt%, due to the high ionic-electronic coupling at the interface between phase-separated regions.
