Dye Sensitized Solar Cells Based on 2-Amino-[(Coumarin-3-yl)-4-(4-(Diphenylamino)Phenyl]nicotinonitrile Fluorescent Dyes.

By introducing novel sensitizer dyes such as ACT, BCT, and SCT, this study seeks to significantly contribute to the field of dye-sensitized solar cells (DSSCs). Modern microwave irradiation has been used to carefully design these dyes. These reaction's outcomes clearly demonstrate how superior this technique is to conventional synthetic approaches. It not only reduces reaction time but also yields better results. A detailed analysis of these novel dyes has demonstrated their superior optical and electrochemical characteristics, which have been validated with the help of Cyclic Voltammetry and UV-Vis spectroscopy. The thorough investigation into solar cell domain involved creation of DSSC devices, where these dyes were used as sensitizers along with Cadmium sulphide Nanowires, as semiconductor material. The results demonstrated a notable increase in the device performance, boosting to 3.67 times the efficiency of bare CdS NW devices. Accompanying these results were Density Functional Theory (DFT) calculations and external quantum efficiency data, pleasantly validating the photovoltaic experiments. This research reveals the fascinating potential of these novel compounds as efficient sensitizers for DSSCs. Furthermore, it confers vital insights into their photovoltaic performance, thereby opening a way to researcher in advancements in solar cell technology.
