Solar Concentration at the Interface between Optics and Thermodynamics

I show how the interface between optics and thermodynamics organizes and informs the design of solar concentrators. This extends from ultra-high concentrating systems of ~ 100,000 suns to stationary systems of ~ 4 X concentrations. Luminescent systems which rely on a Stokes shift to concentrate even diffuse sunlight are discussed.
