Photocurrent/photovoltage has become an important tool in the investigation of passive films. The photovoltages were measured for copper in sodium hydroxide using a high power light source for different durations. The film growth is logarithmic in nature and exhibits positive photopotential as light is shone on them. The auto power of electrochemical noise was measured both in dark and illuminated conditions. Band grap of the film was calculated from the absorption spectrum
