The year that Solar Energy was invented?
When Solar Energy was invented?
The history of solar energy began in 1954, with just a couple of small steps, inspired by scientists and inventors. In the 20th century{,|| it was the time that} the defense and space industries realized the benefits from solar energy. By then it was an attractive however, it was still a costly option to replace fossil fuels. The industry has matured and is today a viable and affordable technology that is rapidly replacing oil, coal, or natural gas within today’s energy market. This timeline will highlight the major pioneers and events that led to the advancement of solar technology.
The Age of Discovery (19th-20th century)
The late 19th century witnessed the birth of physics with discoveries in the fields of electricity, magnetism along with the science of light. The work of scientists and engineers laid the basis for the majority of the development of solar energy.
1839: A 19-year-old Frenchman Alexandre-Edmond Bécquerel designs the first solar cell that was ever built in the world.1 His work on electricity and light influenced later photovoltaics developments. It is the European Photovoltaic Sun Energy Conference and Exhibition awards the Becquerel prize every year.
1861: Auguste (or Augustin) Mathematician and physicist patents an electric motor for solar power.
1873: Willoughby Smith an electrical engineer discovers the photovoltaic effect of selenium.
1876: W. G. Adams (professor of Natural Philosophy, King’s College London) discovers that the resistance to electricity of selenium can change due to radiation heat, light or chemical reaction. “2
1882. Abel Pifre creates a “solar engine” that generates enough electricity for his solar printing press. (pictured below)
The year is 1883. Charles Fritts, an inventor, designs the first solar cells made of silver and. It converts solar radiation into electric power with just 1% efficiency.
1883: John Ericsson, an inventor, develops the sun motor, which uses the parabolic tube (PTC), to concentrate solar radiation to power a boiler steam. PTC is still used in solar thermal power plants.
1884. Charles Fritts places solar panels on a New York City rooftop.
1903: Aubrey Eneas, a Pasadena-based entrepreneur, starts 1903: The Solar Motor Company to market solar-powered steam engines to be used in irrigation projects. Soon, the company fails.
1912-1913: Frank Shuman, an engineer at the Sun Power Company, uses PTC to construct one of the first thermal solar power plants anywhere in the world.
The Age of Understanding Solar Panels (late-19th-early-20th centuries)
Modern theoretical physics has assisted in gaining a better understanding of photovoltaic electricity. Quantum Physics’ description of the subatomic worlds of electrons and photons reveals the mechanism by which packets of light can alter the electrons in silicon crystals to create electric currents.
The year was 1888. Wilhelm Hallwachs, a scientist, describes the physics of photovoltaic cells. This is what we now call”the” Hallwachs Effect.
1905: Albert Einstein publishes, “On a Heuristic Viewpoint Concerning The Creation and Transformation of Light,” that explains how light generates an electrical current through knocking electrons out of certain metal atoms.
1916. Jan Czochralski, a chemist, invents a way to make single crystals out of metal. This is the foundation for creating semiconductor wafers, which remain in use in electronics and solar cells.
1917: Albert Einstein provides a theoretic basis for photovoltaics. Einstein introduces the concept that light is an electromagnetic force-carrying packet.
1929 Gilbert Lewis, a scientist and physicist, invented the term “photons” in 1929, to describe Einstein’s electromagnetic energy packets.
Age of Solar Technology Development (mid-20th Century)
The lab has become no more the ideal place for research that is serious about the development technologies for solar power, based on the invention of monocrystalline silicon cells. It is like other technologies. It was developed from research done by the U.S. defense and aerospace industries. The first application that has been successful of this technology was satellites and space exploration. Although solar energy is extremely efficient but the majority of the technology is not commercially available.

The Age of Solar Power Growth (late-20th century)
Solar technology’s first introductions to commercialization were spurred through the economic crisis in the 1970s. The low prices for oil and the low economic growth a consequence of a lack of oil in developed nations. In the U.S., U.S. government provides financial incentives to commercial and residential solar systems, research and development institutes, demonstration projects that use solar energy in government buildings, as well being regulatory structures to support the current solar industry. Solar panels are now cheaper than ever before, starting at $1,865 per watt back in 1956, to $106 per watt in the year 1976 (prices are adjusted to reflect the year 2019 dollars).
