| description | Mesoporous semiconducting networks exhibit advantageous photoelectrochemical properties. The M13 virus is a versatile biological scaffold that has been genetically engineered to organize various materials into nanowire (NW)-based mesoporous structures. In this study, high-aspect ratio titanium dioxide NWs are synthesized by utilizing M13 viruses as templates, and the NWs are assembled into semiconducting mesoporous networks with tunable structural properties. To understand the effects of different morphologies on the photovoltaic performance, the as-fabricated networks are employed as photoanodes in liquid-state dye-sensitized solar cells (DSCs). Compared with traditional nanoparticle-based photoanodes, the NW-based DSC photoanodes demonstrate much higher electron diffusion lengths while maintaining a comparable light harvesting capacity, thus leading to improved power conversion efficiencies. In addition, the NW-based semiconducting mesoporous thin films are able to load sufficient organolead iodide perovskite materials into the interconnected pores, and the perovskite-coated films are utilized as efficient photoanodes for solid-state organolead iodide perovskite hybrid solar cells and achieve power conversion efficiencies superior to those of liquid-state DSCs. |
