The year that Solar Energy was invented?

The year that Solar Energy was invented?

The history of solar power began in 1954, with just a handful of steps inspired by scientists and inventors. At the turn of 20th-century the defense and space industries realized the potential of solar energy. At the time it was an attractive but expensive alternative to fossil fuels. The field has grown and is today a viable and affordable technology that is rapidly replacing coal, oil, or natural gas within the present energy market. This timeline will highlight the major people and events that contributed to the development of solar technology.

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

The 19th century was the birth of physics with discoveries in magnetism, electricity and the study of light. Scientists and inventors laid the foundation for much of the history of solar energy.

1839: 19-year-old Frenchman Alexandre-Edmond Bécquerel designs one of the first solar cells to be built anywhere in the world.1 His researches on light and electricity inspired the development of photovoltaics in the following years. In the European Photovoltaic Sun Energy Conference and Exhibition award the Becquerel prize each year.

The year is 1861. Auguste (or Augustin) Mathematician and physicist, invents a solar motor.

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

1876 W. G. Adams (professor of Natural Philosophy, King’s College London) discovers that the resistance to electricity of selenium is subject to radiation heat, light or chemical reaction. “2

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

Theoretical physics of the present has helped to create a better understanding of the photovoltaic electricity. Quantum Physics’ description of the subatomic worlds of electrons as well as photons reveals the mechanism by the light-emitting particles alter the electrons in silicon crystals to create electric currents.

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

1916: Jan Czochralski, a chemical engineer, discovers a way to create single crystals from metal. This is the basis of the creation of semiconductor wafers. They remain in use in electronics and solar cells.

1917: Albert Einstein provides a theoretical basis for photovoltaics. Einstein explains that light acts as an electromagnetic wave that is carried by a packet.

1929 Gilbert Lewis, a physicist, coined”photons”, a term coined by physicist Gilbert Lewis “photons” in 1929, to describe Einstein’s energy-based electromagnetic packets.

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

The first commercializations of solar technology were brought on by the energy crisis in the 1970s. The low prices for oil and the low economic growth the result of the shortage of petroleum in industrialized countries. The U.S. government provides financial incentives to commercial and residential solar systems Research and development institutes and demonstration projects that utilize solar energy in government buildings, as well in regulatory structures that help the current solar market. Solar panels are now cheaper than ever before, ranging from $1,865 per watt back in 1956 to $106 per watt in the year 1976 (prices were adjusted for the current price in 2019 dollars).
