Hot carrier solar cells were predicted to surpass the Shockley-Queisser efficiency limit almost four decades ago. To achieve this required drastically reducing the energy loss to the optical phonons in electron and hole relaxation and extracting the hot carriers directly from the device. Unfortunately, these proposed cells have yet to succeed. Recently, a new approach was suggested and is being explored. In this talk, the general state of solar cells and hot carrier solar cells are discussed. In addition, since control of the phonons is required, the general world of non-equilibrium phonons is discussed.
