A differential measurement technique for extracting the complex permittivity of substrate material and the effective conductivity of rough conductor surface is proposed in this paper. In this method, substrate integrated waveguide (SIW) cavity resonators having the same footprints and varied thicknesses are utilized to separate the conductor loss of the top(More)
p-type inorganic hole transport materials of Li, Cu-codoped NiOx films were deposited using a simple solution-based process. The as-prepared films were used as hole selective contacts for lead halide perovskite solar cell. An enhanced power conversion efficiency of 14.53% has been achieved due to the improved electrical conductivity and optical(More)
