Three novel cyanoacetamide decorated phenothiazines (1a-c) have been designed. Structural and photo-physical properties of the molecules 1a-c have been investigated. To better realize the charge transport process involved in the dye-sensitized solar cells (DSSCs), computational studies have been performed using B3LYP and CAM-B3LYP method for the dyes 1a-c. Theoretical findings for DSSCs include LHE (light-harvesting efficiency) and driving forces such as electron injection (ΔGinject) and dye regeneration have been calculated to envisage the most appropriate dyes for the application of DSSC.

Ultrafast hole injection from photoexcited diketopyrrolopyrrole-based dyes into mesoporous NiO films was followed by charge recombination that spanned time scales from pico- to microseconds, which was reflected in large variations in dye regeneration and device solar energy conversion efficiencies.
