Formatted abstract
Dye-sensitized solar cells (DSCs) are promising photochemical solar cells owing to their high efficiency and low cost. In this study, the influence of cell geometry, electrolyte composition, and counter electrode (CE) characteristics on the performance of DSCs was investigated to aim at improving the cell efficiency. Using an U-type cell geometry proposed decreased the internal resistance of DSCs and therefore increased the fill factor and energy conversion efficiency. The addition of DMPII to the I-/I3- based electrolyte increased the open-circuit voltage by decreasing the dark current. Compared to the DSCs with the Pt CE prepared by the thermal decomposition of H2PtCl6, the DSCs with the sputtered Pt CE showed a higher fill factor and short-circuit current density, owing to the high electrical conductivity and enhanced light-reflecting ability of the mirror-like sputtered Pt CE. Based on these results, the energy conversion efficiency of the DSC with the TiO2 porous films fabricated by a room temperature cold spray method was increased from 3.93% to 5.11%. The relatively high efficiency shows that the room temperature cold spray is a prospective method in fabricating nanocrystalline TiO2 films for flexible DSCs.
