A doped semiconductor is dipped into a solution ofelectrolyte. The electrolyte solution contains a redox species witha mid-gap electrode potential. After absorbing a photon in excess of its bandgap energy, the photo excited electron in the conduction band (CB) of a semiconductor moves spontaneously to the interface between the semiconductor and the liquid electrolyte. The hole inthe valence band moves spontaneously away from the solid/liquidinterface and into the bulk of the semiconductor. What is the correct statement about the doping of this semiconductor?
