Layers of CuSCN exhibit high hole mobility, high thermal stability, and exceptional optical transparency across the UV-Vis/NIR spectrum. CuSCN finds application as an alternative to organic hole transport materials such as PEDOT:PSS and Spiro-MeOTAD in perovskite-based solar cells (PSCs). Photovoltaic conversion efficiencies of >20% have been reported in PSCs with CuSCN [5]. In addition, compared to Spiro-OMeTAD the CuSCN-based PSCs have been shown to exhibit better thermal stability.

The optical, structural and charge transport properties of solution-processed films of copper(I) thiocyanate (CuSCN) are investigated in this work. As-processed CuSCN films of ~20 nm in thickness are found to be nano-crystalline, highly transparent and exhibit intrinsic hole transporting characteristics...

The wide bandgap and highly transparent inorganic compound copper(I) thiocyanate (CuSCN) is used for the first time to fabricate p-type thin-film transistors processed from solution at room temperature. By combining CuSCN with the high-k relaxor ferroelectric polymeric dielectric P(VDF-TrFE-CFE), we...
