Materials And Mechanisms For Hot Carrier Solar Cell Absorbers

Hot carrier cells offer the potential for very high efficiencies if slowed carrier cooling can be demonstrated effectively. Various mechanisms of phonon interaction have been identified that can lead to such slowed cooling with classes of materials exhibiting long hot carrier lifetimes. The exact reasons for these are not completely clear, but a study and comparison of the materials and mechanisms will give greater insight into constructed robust hot carrier absorber materials.
