研究目的
Investigating the photovoltaic and photoconductive properties of film composites doped with a tetranuclear copper complex and an intramolecular charge transfer sensitizer.
研究成果
The photovoltaic effect in the studied polymer composites is influenced by the photogeneration of charge pairs, their dissociation, and the transport of free charge carriers. The introduction of the metal complex enhances the efficiency of photogeneration of charge carriers, suggesting potential for developing new organic photovoltaic materials.
研究不足
The study is limited to the specific polymer composites and dopants used, and the findings may not be generalizable to other materials or conditions. The experimental setup and measurements are constrained by the equipment and methods employed.
1：Experimental Design and Method Selection:
The study involved preparing samples with a free SPC surface and measuring their optical density spectrum, electric potential, and photovoltaic properties under visible light irradiation.
2：Sample Selection and Data Sources:
Samples were prepared with a copolymer of styrene with nonyl methacrylate and poly-N-epoxypropylcarbazole doped with the tetranuclear copper complex and/or an intramolecular charge transfer sensitizer.
3：List of Experimental Equipment and Materials:
A dynamic probe (Kelvin method), a 5-mW light diode laser, and a storage oscilloscope were used.
4：Experimental Procedures and Operational Workflow:
The photovoltaic effect was measured by irradiating the samples with visible light and recording the changes in electric potential over time.
5：Data Analysis Methods:
The kinetic curves for the electric potential changes were analyzed to determine the photoconductive and photovoltaic properties of the composites.
