Copper(I) thiocyanate is a hole conductor, a semiconductor with a wide band gap (3.6 eV, therefore transparent to visible and near infrared light). It is used in photovoltaics in some third-generation cells as a hole transfer layer.
It acts as a P-type semiconductor and as a solid-state electrolyte.
It is often used in dye-sensitized solar cells.
Its hole conductivity is however relatively poor (0.01 S·m−1).
This can be improved by various treatments, e.g. exposure to gaseous chlorine or doping with (SCN)2.

CuSCN with NiO act synergically as a smoke suppressant additive in polyvinyl chloride (PVC).

CuSCN precipitated on carbon support can be used for conversion of aryl halides to aryl thiocyanates.

Copper thiocyanate is used in some anti-fouling paints. Advantages compared to cuprous oxide include that the compound is white and a more efficient biocide.
