Used as a p-type organic semiconductor in organic field-effect transistors (OFETs) due to its high hole mobility and excellent thermal stability. Commonly employed in the active layer of organic photovoltaic (OPV) cells, especially in tandem solar cells, where it acts as a donor material when paired with fullerene or non-fullerene acceptors. Its extended π-conjugated structure enhances light absorption and charge transport, improving power conversion efficiency. Also utilized in flexible electronics and printed circuits because of its solution-processability, enabling low-cost, large-area fabrication techniques like spin coating or inkjet printing.
