Donor Functionalized Perylene and Different π-Spacers Based Sensitizers for DSSC Applications - A Theoretical Approach

Perylene based novel organic sensitizers for the Dye sensitized solar cell applications are investigated by using Density functional theory (DFT) and time dependant density functional theory (TD-DFT).The designed sensitizers have perylene and dimethylamine (DM) and N-N-dimethylaniline(DMA) functionalized perylene for the dssc applications.π-spacers are thiophene andcyanovinyl groups and cyanoacrylic acid is chosen as the acceptor for the designed sensitizers. The studied sensitizers were fully optimized by density functional theory at B3LYP/6-311G basis set on gas phase and DMF phase. The electronic absorption of the sensitizers is analyzed by TD-DFT at B3LYP/6-311G basis set in both gas and DMF phase.

Structural features of indoline donors in D-A-π-A type organic sensitizers for dye-sensitized solar cells

We report three newly synthesized D-A-π-A metal-free organic sensitizers for dye-sensitized solar cells (DSSCs) based on benzo[c][1,2,5]thiadiazole as an internal acceptor (A) and N-substituted indolines fused with cyclopentane or cyclohexanes...

D-A-π-A Organic Sensitizers Surface Passivation for Efficient and Stable Perovskite Solar Cells

Organic-inorganic hybrid lead perovskite films are crucial in the perovskite solar cells (PSCs). However, the solution deposition process caused the polycrystalline feature of perovskite films with a large number of...
