Potential of a new pyrene based chalcone as a dye on DSSC solar cell and optical limiting

Abstract

Herin, this work focuses on the potential of a pyrene-based chalcone named EDPP1 as a sensitizer in DSSC using density functional theory (DFT) concerning FMO and UV-Vis absorption spectrum. The EDPP1 compound was synthesized using Claisen-Schmidt reaction and characterized via FTIR, UV-Vis absorption, and DFT. UV-Vis absorption spectrum revealed that the bandgap of the EDDP1 is E g = 3.5e V with fully transmittance above λ cut off = 499nm and high absorption at UV region. The energy level diagram suggests that EDPP1 is a promising sensitizer in DSSCs as it meets the required dye conditions. Additionally, optical limiting study revealed that the EDPP1 compound has the ability to limit laser power above 875 mW. Overall, these results suggest that EDPP1 has potential as a sensitizer in DSSCs and as an optical limiter.
