• Dye-sensitized solar cell
• Alternating assembly structure
• Dye-modification material
• N3-dye
• Molecular aggregation

Only one sort of dye and a dye-modification material is used to form an alternating assembly structure in dye-sensitized solar cell. The alternating assembly can increase the adsorption of dye sensitizer, prohibit the aggregation of the dye, and retard the recombination reaction. These effects are investigated by ultraviolet-visible spectrum, Fourier transform infrared spectrum, transient photovoltages, current density-voltage characteristics and dark current measurements. The photon-electron conversion efficiency of the cell with alternating assembly structure rise by 16%, from 3.86% to 4.49% under AM 1.5 irradiation. And the stability of the cell is also improved.
