Improved CuSCN-ZnO diode performance with spray deposited CuSCN

► CuSCN depositions using impregnation and a spray technique are compared. ► ZnO nanorod-CuSCN diodes were fabricated to demonstrate device performance. ► Hall mobility measurements show good conductivity of CuSCN films. ► Spray deposition improved film morphology and reduced device production time. ► Device rectifications are higher than previously reported for ZnO-CuSCN diodes.
