Abstract
A dye-sensitized solar cell with hybrid nanostructures comprises a negative-polarity conductive substrate, a metal oxide layer, a positive-polarity conductive substrate and an electrolyte. The metal oxide layer has a plurality of nanoparticles and a plurality of nanotubes. The metal oxide layer and the electrolyte are arranged between the negative-polarity conductive substrate and the positive-polarity conductive substrate. The nanoparticles increase contact area with dye and thus enhance power generation efficiency. The nanotubes increase carrier mobility and thus effectively transfer electricity to electrodes. The solar cell integrates the advantages of nanoparticles and nanotubes and offsets the disadvantages thereof to effectively enhance the photovoltaic conversion efficiency of dye-sensitized solar cells.
