Used as an electron-accepting material in organic photovoltaic (OPV) devices, this compound enhances charge separation and electron transport due to its strong electron-deficient character and extended π-conjugation. It is commonly employed in the active layer of organic solar cells, where it pairs with electron-donor polymers to improve power conversion efficiency. Its rigid, planar structure promotes good film-forming properties and thermal stability, making it suitable for use in thermally evaporated or solution-processed devices. Additionally, it finds application in perovskite solar cells as an interfacial layer to reduce recombination and improve device performance.
