We have clarified that generated polarons achieve H2 molecule generation through photocatalytic reactions. Two-photon excitation for polaron has been considered via isolated states. Two-photon excitation can be calculated through itinerant to isolated and isolated to itinerant state excitations. The repeated excitation under more than 1 percent defect is large enough, compared with direct bandgap excitation in our theoretical work.
