Used as an electron-accepting material in organic solar cells, particularly in bulk heterojunction photovoltaic devices. It functions as a non-fullerene acceptor, offering strong absorption in the visible to near-infrared range, which enhances light harvesting and improves power conversion efficiency. Its molecular structure supports effective charge separation when paired with common donor polymers and enables good film morphology in device fabrication. Exhibits high electron mobility and tunable energy levels, making it suitable for use in flexible and lightweight solar cells. Also explored in tandem solar cells to broaden spectral response and increase overall efficiency.
