The first part of this article presents experimental results on novel devices that were fabricated and operated by utilizing dressed photons. The fabricated devices were photovoltaic devices having an Ag-electrode with a unique surface morphology, light-emitting diodes using silicon crystals, and nano-droplets in which pairs of nanometer-sized semiconductor particles were confined. The second part reviews the results of the numerical simulations for these devices using a random walk model. This model relies on statistical mechanics and complex-systems science. The third part describes the problems with these simulations and presents some suggestions for solving them. Finally, the need for a three-dimensional off-shell scientific model that takes account of interactions in a nanometric space is pointed out.
