Abstract

Organic–inorganic halide perovskites show great potential, but their commercialization faces challenges due to instability, requiring controlled synthesis environments. Antisolvent engineering offers a solution by improving the formation of perovskite films under ambient conditions. In this study, CsPbBr3 nanocrystals (NCs) were added to the antisolvent to enhance the performance and stability of perovskite solar cells (PSCs). By optimizing the NC concentration and the mixing ratio of antisolvents, we systematically examined their impact on film deposition. The inclusion of CsPbBr3 NCs improved PSC efficiency, with the highest power conversion efficiency of 19.99 % achieved at 0.01 mg/mL NC concentration. Additionally, NC-added films demonstrated better long-term stability, losing only 12.5 % efficiency after 80 days compared to a 47.1 % loss in pristine films. These results highlight the potential of NC-assisted antisolvent engineering for producing stable, high-performance PSCs.

期刊介绍: Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications. Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques. Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals. Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review. The Journal is owned by the Korean Physical Society.
