Used as an organic semiconductor in organic photovoltaic (OPV) cells due to its strong electron-accepting properties and ability to absorb visible light efficiently. It serves as a key building block in donor-acceptor copolymers for high-performance polymer solar cells. Its planar structure promotes good π-π stacking, enhancing charge carrier mobility in thin-film transistors and improving device efficiency. Also explored in perovskite solar cells as a hole-transport material component. Shows promise in flexible electronics and wearable energy devices owing to its solution processability and thermal stability.
