Abstract (Summary)

Metal-Organic Frameworks (MOFs) are versatile materials that can be modified or tuned to enhance photovoltaic performance. Recently, there has been an interest in integrating these materials into Dye-Sensitized Solid-State Solar Cells (DSSC) as the dye-sensitizing material. This will enhance the overall power output by creating a physical separation between the electron-hole pair. Separating the electron-hole pair will also affect the electronic lifetimes, leading to longer lifetimes by the decrease of charge recombination. These materials are tunable materials, meaning both the metal and the organic linker can be designed to obtain specific purposes. For example, MOFs used in photovoltaic research can be designed to have large linkers providing the physical separation between the electron hole pair. In addition, having a large conjugated linker can promote the movement of electrons. The goal of this project is to design and synthesize a specific organic linker that will enhance the overall power output of a photovoltaic cell. The placement of the MOF will be between the titanium dioxide layer and hole-transmitting material (HTM), replacing the traditional organic dye-sensitizing molecule. In this study, we are able to synthesize an organic linker with adamantane core and construct a photovoltaic system using this linker. The structure and performance of the photovoltaic cell were also studied.
