We have investigated the insights of photo-physical surface characteristics for Ru (II)
polypyridyl dye (N719) sensitization and its performance in dye-sensitized solar cells (DSSCs)
at different temperatures of ZnO-based photoanodes. The maximum power conversion
efficiency of 2.25% with a high open-circuit voltage of 0.87 V was recorded for 40oC sensitized
device under 1SUN 1.5 AM. The 60oC sensitized device shows the maximum current density
of 8.8 mA.cm-2 and 25oC sensitized device results. Therefore, the mode of surface interaction
of N719-ZnO to promote better electron conduction has highlighted the prospects of DSSCs
under diverse solution sensitization temperature environment.
