| Outline of Annual Research Achievements |
During the first year of study, significant progress was made in cultivating M13 bacteriophage and synthesizing various analogous biomaterials, both natural and nature-inspired, with the goal of applying them to perovskite solar cells as additives for thin-film crystal growth promotion and templates. We explored cellulose-based materials, spider web-induced materials, and carbon nanotubes to enhance the functionality of these biomaterials. The synthesis of these materials has been successful, and we have also authored a comprehensive review paper on our findings, which has been published in a Wiley journal. This foundational work sets the stage for further development and application of these materials in enhancing the efficiency and stability of tin-based perovskite solar cells.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The shift in research focus from exclusively using M13 bacteriophage to incorporating carbon nanotubes and natural materials such as cellulose and spider web-induced materials was driven by several compelling reasons. Initially, the unique properties of M13 bacteriophage, including its ability to self-assemble and its functional versatility, offered promising avenues for enhancing the efficiency and stability of tin-based perovskite solar cells. However, as the research progressed, it became evident that integrating carbon nanotubes and natural materials could provide additional benefits that complement the bacteriophage's capabilities. Carbon nanotubes are renowned for their exceptional electrical conductivity and mechanical strength, which can significantly improve the charge transport and structural integrity of the perovskite films. Meanwhile, cellulose and spider web-inspired materials offer sustainable, biocompatible alternatives with unique mechanical properties and surface functionalities that can further optimize the thin-film crystal growth and overall device performance. By expanding the scope to include these materials, the research aims to leverage the synergistic effects of combining biogenic and synthetic materials, ultimately leading to more robust, efficient, and environmentally friendly perovskite solar cells.

| Strategy for Future Research Activity |
The research scheme for the subsequent years builds on the foundational work completed in the first year and focuses on optimizing the M13 bacteriophage, cellulose-based materials, and spider web-induced biomaterials. In the second year, targeted peptides with amino acid functional groups inhibiting Sn4+ ion oxidation will be identified using simulations and FT-IR, followed by developing new M13 bacteriophage strains through genetic engineering. Additionally, the synthesis and integration of cellulose and spider web-based materials will be enhanced to serve as effective templates and growth promoters for perovskite thin-film crystals. The scale-up production and advanced characterization of these materials will be prioritized, alongside exploring their interaction with tin-based perovskites and potential metallic functionalization. In the third year, efforts will shift towards optimizing the composition of tin-based perovskite materials, refining film formation techniques, and evaluating the photophysical properties of the films using various spectroscopic methods. This includes determining the radiative and non-radiative recombination rate constants to improve the overall film quality and material properties, ultimately aiming to enhance the efficiency and stability of tin-based perovskite solar cells.
