For the first time a detailed photoelectrochemical study of n-type nickel phosphide (Ni2P) material (thin film as well as powder) is reported. This material has a hexagonal structure with a band gap of 1.0 eV. The band edge positions are calculated using electron spectroscopy for chemical analysis. The compound is found to be stable in alkaline and acidic media. The photoconversion efficiency found to be 0.26%.
