When Solar Energy was invented?

The history of solar energy began in 1954, with just a couple of small steps, driven by scientists and inventors. In the 20th century{,|| it was the time that} the space and defense industries realized the benefits in solar power. At the time, it was a promising but expensive alternative to fossil fuels. The field has grown and is today a viable and affordable technology that is quickly replacing coal, oil, and natural gas in today’s energy market. This timeline highlights the most important innovators and the events that led to the development of solar technology.

The Age of Discovery (19th-20th century)

The late 19th century witnessed the beginning of physics, with discoveries in electricity, magnetism as well as the research of light. Scientists and inventors laid the basis for much of the history in the field of solar energy.

1839: 19-year-old Frenchman Alexandre-Edmond becquerel creates the first solar cell to be built anywhere in the world.1 His work on electricity and light influenced subsequent developments in photovoltaics. In the European Photovoltaic Sun Energy Conference and Exhibition award the Becquerel prize every year.

1861: Auguste (or Augustin), a mathematician and physicist, patents an electric motor for solar power.

1873: Willoughby S. Smith, an electrical engineer, discovers photovoltaic properties of selenium.

1876: W. G. Adams (professor of Natural Philosophy, King’s College London) discovers that the resistance to electricity of selenium may change due to radiation light, heat or chemical action. “2

1882: Abel Pifre creates a “solar engine” which produces enough power to power his solar printing press. (pictured below)

The year is 1883. Charles Fritts, an inventor, creates the first solar cells using selenium and gold. The cells convert solar radiation into electricity with a mere 1% efficiency.

1883: John Ericsson, an inventor, designs a sun motor that uses the parabolic tube (PTC) to concentrate solar radiation to generate boiler steam. PTC is still utilized to power solar thermal plants.

1884: Charles Fritts places solar panels on a New York City rooftop.

1903: Aubrey Eneas, a Pasadena-based entrepreneur, launches The Solar Motor Company to market solar-driven steam engines for irrigation projects. The company soon fails.

1912-1913: Frank Shuman, an engineer with the Sun Power Company, uses PTC to construct the first solar thermal power plant in the world.

The Age of Understanding Solar Panels (late-19th-early-20th centuries)

Modern theoretical physics has helped to create a better understanding of the photovoltaic electricity. Quantum Physics’ description of the subatomic realms of electrons and photons reveals the mechanism by which light particles can alter the electrons in silicon crystals to create electric currents.

1888: Wilhelm Hallwachs, a physicist, describes the physics behind photovoltaic cells. This is what we now call”the” Hallwachs Effect.

1905: Albert Einstein publishes, “On an Heuristic Perspective on the Production of Light and the Transformation of Light,” which explains how light creates an electrical current by 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 principle behind creating semiconductor wafers, which remain in use in electronics and solar cells.

1917. Albert Einstein provides a theoretic basis for photovoltaics. He introduces the idea that light acts as an electromagnetic force-carrying packet.

1929: Gilbert Lewis, a scientist, coined”photons” in 1929 “photons”, to describe the electromagnetic energy of Einstein’s packets.

Age of Solar Technology Development (mid-20th Century)

The laboratory has become no more the best place to conduct serious research into the advancement in solar technology based upon the discovery of monocrystalline silicon cells. It is like other technologies. It was created from research conducted for U.S. defense and aerospace industries. The first successful application of this technology was research and satellites. Even though solar energy is extremely efficient however, the majority of its technology isn’t commercially viable.

1962 Telstar, the first satellite-powered solar communications satellite, is powered by 3,600 cells manufactured by Bell Laboratories.

1967: Soviet Union’s Soyuz 1 is the first spacecraft powered by solar energy to transport humans.

1972 1972: The Synchronar 2100 watch powered by solar goes on sale.

Age of Solar Power Growth (late-20th century)

The first commercializations of solar technology were spurred through the economic crisis of the 1970s. The low prices for oil and the low economic growth a consequence of a lack of petroleum in industrialized countries. In the U.S., U.S. government provides financial incentives to residential and commercial solar systems, research and development institutes, demonstration projects that use solar electricity in government buildings as well as regulatory structures that support the current solar industry. Solar panels are more affordable than ever before, starting at $1,865 for a watt in 1956 to $106 per watt in 1976 (prices adjusted for 2019 dollars).
