YD2 is widely used in the field of dye-sensitized solar cells (DSSCs) due to its efficient light-harvesting properties. It serves as a photosensitizer, absorbing sunlight and converting it into electrical energy, which enhances the overall performance of the solar cells. Its molecular structure is optimized for broad spectral absorption, making it effective in capturing a wide range of solar wavelengths. Additionally, YD2 is utilized in research and development to improve the efficiency and stability of next-generation photovoltaic devices. Its application extends to studies focused on optimizing charge transfer processes and reducing energy loss in solar energy conversion systems.
