| Popis: | Hybrid organic-inorganic double-layered structures are fabricated from Zinc Phthalocyanine (ZnPc) and Gallium Arsenide (GaAs). The inclusion of GaAs interlayer widens the absorption spectrum of ZnPc. Photoluminescence (PL) shows that GaAs quenches emission from the ZnPc suggesting carriers transfer to GaAs. Time-resolved fluorescence spectroscopy shows the molecular orientation of ZnPc tunes fast charge transport. The ZnPc/GaAs/ZnPc hybrid structure possess the ability to a wide range of absorption as evident in ultraviolet–visible (UV–Vis) absorption studies and charge carrier extraction from PL analysis are suitable for solar cell application. |
