It has been shown that dressed photon (DP) energy transfer exhibits unique autonomous spatial evolution features, and novel functional devices have been demonstrated as a first example of the practical application of this transfer. Temporal evolution features originating from nutating DP energy transfer followed by radiative relaxation have also been demonstrated. A novel film for highly efficient optical energy conversion is presented as a second example of the application of these features. It is suggested that these spatial and temporal evolution features can be analyzed based on theoretical models based on a quantum walk and a random walk. This film was placed on a silicon solar battery to convert UV light energy to visible light energy, resulting in an increased electrical power generation efficiency of 20.2%.
