Here we report on the development of a protective coating based on thin and electrically conductive nanocrystalline boron-doped diamond (BDD) layers. We found that BDD layers protect the underlying Si photoelectrodes over a wide pH range (1-14) in aqueous electrolyte solutions. BDD layer maintains an efficient charge carrier transfer from the underlying silicon to the electrolyte solution.
