Widely used in photovoltaic and photoelectrochemical systems, this compound serves as a key photosensitizer in dye-sensitized solar cells (DSSCs). It efficiently absorbs visible light and facilitates electron injection into semiconductor substrates like titanium dioxide, enabling solar energy conversion. Its robust photochemical stability and tunable redox properties make it ideal for long-term operation in solar devices. Additionally, it is employed in artificial photosynthesis research, where it acts as a light-harvesting component in systems designed for water splitting and solar fuel production. The compound also finds use in electrochemiluminescence (ECL) applications due to its strong luminescent response under electrical excitation, useful in analytical assays and biosensors.
