Aliphatic mixed ligands Sn(II) complexes as photon absorbers in quantum dots sensitized solar cell

Dye-sensitized solar cells have attracted a lot of research interest due to the quest for an alternative energy supply given that it is cost-effective and its materials are easily available. However, need improve conversion efficiency these cell devices has necessitated search new will lead more conversion. One such material tin (II) sulfide (SnS). In present study, we report results from synthesis hexadecylamine (HDA)-capped SnS uncapped photosensitizer using molecular precursor. The photon absorbers, their morphological, structural electrochemical properties were examined different techniques. Both photosensitizers displayed X-ray diffraction (XRD) peaks within range 26.03°–66.05°, which corresponds orthorhombic structure. Field Emission Scanning Electron Microscope (FE-SEM) High-Resolution Transmission (HRTEM) further revealed HDA-capped better morphology size distribution. UV–Vis analysis shows exhibits strong absorption in entire visible region attributed perfect orientation. superiority was linked well reduced electron recombination lifetime. addition HDA capping agent improved J-V performance with 8.20%. Results obtained work proselytize concept as approach improving quality absorbers.
