Sensitized up-conversion (SUC) based on bi-component systems is currently indicated as a potential method to improve the efficiency of PV and PC technologies by photon energy managing. Although high SUC yields have been already demonstrated in solution by using low power non-coherent excitation sources, its application in real devices is still far. Indeed the conversion yield drops dramatically at solid state, where the short diffusion length of excitation energy strongly inhibits the diffusion controlled mechanisms which rule SUC photophysics. A general discussion to analyze the main environmental parameters affecting SUC quantum yield is presented here to find out the guidelines for the fabrication of high performance SUC materials.
