The following computer simulation http://phet.colorado.edu/en/simulation/photoelectric contains a serious error: if you in the saturation (U >> 0V) with the same intensity change the wavelength of light, the photocurrent also changes:

But that should not happen! About cut-off frequency the photocurrent in the saturation depends only from the intensity of light:
