Used in organic photovoltaics as a donor material in bulk heterojunction solar cells due to its strong light absorption in the visible and near-infrared range. Exhibits high charge carrier mobility, making it suitable for organic field-effect transistors. Also applied in organic photodetectors for its sensitivity to specific wavelengths. Processable from solution, enabling low-cost, large-area fabrication on flexible substrates. Shows good thermal and environmental stability, beneficial for long-term device performance.
