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 ZnO-based photoanodes. The maximum power conversion efficiency 2.25% with a high open-circuit voltage 0.87 V was recorded 40 °C sensitized device under 1SUN 1.5 AM. 60 shows current densit...
