Apparatus for the Utilization of Radiant Energy

Another theory Tesla proposed that is now common is that of the presence of photons in rays of light and other electromagnetic rays. To prove such a point, his experiments led to an Apparatus for the Utilization of Radiant Energy, which is basically a precursor to modern solar cell technology and other photoelectric devices.
