A device and method for producing electricity by harnessing sunlight to produce an amplified voltage signal, the device including: (a) a sealed chamber, defined by a transparent housing; (b) an excitable medium, disposed within the chamber, in which, when the medium is exposed to solar light having wavelengths in a range of 0.2 to 3 micrometers, bound electrons in the excitable medium are elevated to at least one higher energy state; (c) electrodes, disposed in a spaced apart fashion, whereby the medium is between, and fluidly communicates with, the electrodes; (d) an electric circuit, the medium and the electrodes completing the circuit; (e) an initiating mechanism, adapted to initiate an initial voltage signal through the chamber, between the electrodes, and (f) a power source, associated with the circuit, and adapted to maintain the first voltage signal through the chamber, between the electrodes, whereby the bound electrons in the higher energy state transfer energy to free electrons traversing the first voltage signal to produce the amplified voltage signal, and wherein the excitable medium is selected, and adapted within the chamber, to absorb at least 5% of an energy flux within a wavelength range of 0.2 to 3 micrometers, emitted by a black body operating at 5500K, by elevating the bound electrons to the higher energy state.
