NOVELTY - A dye-sensitized solar cell comprises cathode having conductive surface; anode having film of zinc oxide aggregate particles; and electrolyte disposed between cathode and anode. The zinc oxide aggregate particles have been synthesized in the presence of deliberately added lithium ions and comprised constituent particles. The zinc oxide aggregate particles further have been sensitized in dye. The dye is capable of absorbing photons and transferring photoexcited electrical charge to zinc oxide aggregate particles. The electrolyte provides electrical pathway between cathode and anode.    USE - A dye-sensitized solar cell used for converting solar energy into electricity.    ADVANTAGE - The use of lithium during synthesis results in zinc oxide aggregates that have advantageous microstructure, morphology, crystallinity and operational characteristics. When used in solar cell, the zinc oxide aggregates are capable of yielding devices having conversion efficiencies as high as 6.1%. With further optimization, the conversion efficiencies are expected to increase. The synthesis of zinc oxide aggregates in the presence of lithium provides aggregate-forming nanocrystallites with improved crystallinity and more favorable facets for dye molecule absorption. The lithium synthesis improves surface stability of zinc oxide in acidic dyes to enable monolayer absorption of dye molecules on zinc oxide nanocrystallites. Monolayer absorption favors electron injection at dye-semiconductor interface, thus reducing energy loss in dye-sensitized solar cells. The lithium mediated growth improves porosity of zinc oxide aggregates, which is important to both dye absorption and electrolyte infusion. The procedures help ensure the formation of aggregate film that has high homogeneity of thickness, high packing density, high specific surface area and good electrical contact between film and fluorine-doped tin oxide electrode and among aggregate particles.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for fabrication of dye-sensitized solar cell, comprising synthesizing zinc oxide aggregate particles in the presence of deliberately added lithium ions; adding photosensitive dye into zinc oxide aggregate particles; preparing anode including photoelectrode film that includes zinc oxide aggregate particles placed on conductive substrate; preparing cathode including conductive surface; and placing electrolyte between anode and cathode.
