Mr. Einstein quotes about sun energy from 1905 point that the energy of the sun was “unexploited” since we are not taking into account all its potential. Per Einstein´s research at that time, light contains tiny packets of energy called “quanta” which now we know as photons.
The amount of this particles said, it varies depending to its wavelength, so the shortest wavelengths used to be the ones that has more energy potential.
Selenium used to be the material that started everything for its peculiarities to “save” somehow energy from the sun and turn it into electricity, which was a process called photoelectric, but by the 1920s science folks referred to the phenomenon “photovoltaic” effect.
This discovery triggered deep analysis into the photovoltaic effect and new dreams for sustained energy from the sun, the rest is history…
