What is the useful energy of a photon?

The fundamental upper bound on the efficiency of photovoltaic conversion continues to attract interest of the research community. By considering the conversion efficiency of a monochromatic photon gas at constant pressure, we show that this limit is equal to the availability (or exergy), as defined...
