Copper thiocyanate is primarily used in the field of organic electronics due to its excellent hole-transport properties. It serves as a p-type semiconductor in organic photovoltaic cells (OPVs), helping to improve device efficiency by facilitating the movement of positive charges. It is also employed as a buffer layer in organic light-emitting diodes (OLEDs) and perovskite solar cells, where it enhances energy level alignment and reduces recombination losses. Its thermal stability and solution-processability make it suitable for low-cost, large-area electronic devices. Additionally, copper thiocyanate finds use in some antimicrobial coatings and as a precursor in the synthesis of other copper-based materials.
