Nanoscience for Innovative Dye Sensitized Solar Cells

摘要

Innovative nanonetwork composed of oxide nanoparticles and singlecrystallinernZnO nanowires is demonstrated as efficient photoanode inrnexcitonic solar cells. Such architecture benefits of the capability of highrnsensitizer loading offered by the nanoparticles and of the directrnconduction path for electrons guaranteed by the single-crystalrnnanowires. The combination of these features leads to improved lightrnabsorption, electron photogeneration, and charge collection. Variousrntypes of nanonetwork were implemented in a dye-sensitized solar cellrnarchitecture demonstrating great enhancement of the efficiency withrnrespect to a nanowire photoanode of the same thickness.
