Abstract

A composite made of electrospun TiO₂ nanofibers and conventional TiO₂ nanoparticles is an innovative type of photoanode, which noticeably improves the harvesting of light without substantially sacrificing the attachment (uptake) of dye molecules for convenient fabrication of dye-sensitized solar cells with significantly improved efficiency.
