Hybrid Structure of Organic-Inorganic Photovoltaic Fast Carrier Transport

Hybrid organic Copper phthalocyanine (CuPc) –inorganic Cadmium Sulfide (CdS), double layered structures were deposited on glass substrate at different thickness using Pulsed Laser Deposition (PLD) with Q-Switching Nd: YAG laser with energy (240,500 mJ) at (25 Celsius) and within vacuum conditions of (10 -3 torr). The photoluminescence (PL) is showing that the CdS quenches emissions from CuPc indicating the carrier transfer to the CdS. Also, the CuPc/CdS hybrid structures have the capability for various absorptions as can be seen in the ultraviolet-visible absorption researches and the charge carrier extractions from PL analysis have been adequate for the solar cell applications. FT-IR spectra have been specified for CdS and CuPc.
