Free QuoteSolar energy: the theoretical basis The conversion of solar radiation into heat and electricity is at the heart of any transition to sustainable energy systems. But before reviewing the various technologies for achieving this, a detour into the theoretical basis of this energy source is essential.
Solar panels, now synonymous with the pursuit of clean energy, can trace their roots back to the 19th century. The seminal discovery of the photovoltaic effect by French physicist Alexandre Edmond Becquerel in 1839 laid the theoretical groundwork for what was to come.
The theory of solar PV energy conversion can be classified broadly on the basis of dual nature of solar radiation, i.e. particle and wave nature.
Only a few years later in 1888, inventor Edward Weston received two patents for solar cells – U.S. Patent 389,124 and U.S. Patent 389,425. For both patents, Weston proposed, “to transform radiant energy derived from the sun into electrical energy, or through electrical energy into mechanical energy.”
That same year, a Russian scientist by the name of Aleksandr Stoletov created the first solar cell based on the photoelectric effect, which is when light falls on a material and electrons are released. This effect was first observed by a German physicist, Heinrich Hertz.
Named after Italian physicist, chemist and pioneer of electricity and power, Alessandro Volta, photovoltaic is the more technical term for turning light energy into electricity, and used interchangeably with the term photoelectric. Edward Weston's "Apparatus for Utilizing Solar Radiant Energy," patented September 4, 1888. U.S. Patent 389,124
