This technology relates to a method for manufacturing a metal oxide composite thin film, a metal oxide composite thin film manufactured using the same, a method for manufacturing a perovskite photovoltaic device, and a perovskite photovoltaic device manufactured using the same. In particular, it is a technology designed to enhance the performance, structural stability, and application efficiency of chemical composition and reaction control based on the use of functional ligands to control surface defects and improve the conductivity of metal oxide nanoparticles.
Conventionally, problems such as the dispersion stability of metal oxide nanoparticles and conductivity issues caused by organic ligands that hinder charge transfer have led to performance degradation, process complexity, lack of stability, or limitations on the scope of application. Accordingly, this technology proposes a technical concept that utilizes a method for manufacturing a metal oxide composite film as a core means to implement a step of preparing a metal oxide nanoparticle dispersion solution in which a first nanoparticle, which is a metal oxide nanoparticle surrounded by an organic ligand, is dispersed in a first dispersion solvent.
Accordingly, by removing the aforementioned organic ligand and introducing the aforementioned functional ligand, an effect on the dispersion stability of the metal oxide nanoparticles can be expected. Furthermore, through the use of functional ligands to control surface defects and enhance the conductivity of the metal oxide nanoparticles, stability, reproducibility, and scalability in real-world application environments can be simultaneously improved. Additionally, this offers the potential to be utilized as a high-performance material, device, apparatus, or process technology in related industries. It is advantageous in terms of subsequent commercialization and process expansion, and is also suitable for demonstration deployment.
