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 40 °C sensitized device under 1SUN 1.5 AM. The 60 °C sensitized device shows the maximum current density of 8.8 mA cm−2 and 25 °C 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.
