研究目的
To analyze the effect of steric hindrance on the photoelectric performance of three different donor sensitizers (ZHG5, ZHG6, and ZHG7) and to explore the enhancement of optical properties through hybridization with graphene quantum dots and insertion of functional groups.
研究成果
The study concludes that steric hindrance negatively affects the performance of sensitizers, while hybridization with graphene quantum dots and insertion of -CN functional groups can enhance optical properties. The designed molecules show potential for improving dye-sensitized solar cells' efficiency.
研究不足
The study is limited to theoretical simulations and does not include experimental validation. The impact of steric hindrance and functional group insertion is analyzed in silico, which may not fully capture real-world performance variations.
1：Experimental Design and Method Selection:
The study employs density functional theory (DFT) and time-dependent DFT (TD-DFT) for analyzing ground-state and excited-state performance of sensitizers. B3LYP/6-31g(d) was used for optimizing geometries and frontier molecular orbitals.
2：Sample Selection and Data Sources:
Three sensitizers (ZHG5, ZHG6, ZHG7) were selected based on their steric hindrance properties.
3：List of Experimental Equipment and Materials:
Gaussian 09 software was used for theoretical calculations.
4：Experimental Procedures and Operational Workflow:
The study involved simulation of photoelectric physical and photochemical parameters, including frontier molecular orbital analysis, global reactivity descriptors, optical absorption properties, and charge density difference.
5：Data Analysis Methods:
The Newns-Anderson approach was used for simulating interfacial electron transfer time from sensitizers to a semiconductor.
