Black cobalt thin films on bright nickel plated on brass and copper substrates were prepared by the electrodeposition method. The Influence of substrate metal and heat treatment process on the surface morphology and absorptance of samples was investigated. Surface morphology and spectral reflectance of films were measured by scanning electron microscopy and spectrophotometer in the visible and near-IR region of spectrum respectively. Scanning electron microscopy images showed that the black cobalt films have porous structure. The absorptance of prepared films is over than 90%; which makes them suitable for using as solar absorbers.
