What was the year Solar Energy was invented?
When Solar Energy was invented?
The history of solar energy began in 1954, with just a few small steps, inspired by scientists and inventors. At the turn of 20th-century{,|| it was the time that} the defense and space industries realized the benefits from solar energy. In the early days it was a promising, but still expensive, option to replace fossil fuels. The industry has matured and is today a viable and affordable technology that is quickly replacing coal, oil or natural gas within the present energy market. This timeline will highlight the major innovators and the events that led to the creation of solar technology.
The Age of Discovery (19th-20th century)
The mid-19th century saw the beginning of physics thanks to discoveries in magnetism, electricity and the study of light. The work of scientists and engineers laid the basis for much of the history of solar energy.
1839: A 19-year-old Frenchman Alexandre-Edmond Bécquerel designs his first photovoltaic cell anywhere that was ever built in the world.1 His researches on light and electricity inspired later photovoltaics developments. The European Photovoltaic Sun Energy Conference and Exhibition award the Becquerel award each year.
1861 Auguste (or Augustin) Mathematician and physicist patents a solar motor.
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 electrical resistance of selenium can change due to radiation light, heat or chemical action. “2
1882. Abel Pifre creates a “solar engine” which produces enough electricity to power its solar-powered printing presses. (pictured below)
In 1883, Charles Fritts, an inventor, designs the first solar cells made of selenium and gold. It converts solar radiation to electric power with just 1% efficiency.
1883: John Ericsson, an inventor, develops a sun motor that uses parabolic tube construction (PTC) to concentrate solar radiation to power a boiler steam. PTC continues to be employed to power solar thermal plants.
1884: Charles Fritts places solar panels on a New York City rooftop.

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 realms of electrons and photons reveals the mechanism by the light-emitting particles alter the electrons in silicon crystals, causing electrical currents.

1905: Albert Einstein publishes, “On a Heuristic Approach to The Creation as well as the Transformation of Light,” which explains how light creates an electrical current through knocking electrons away from specific metal atoms.
1916: Jan Czochralski, a chemical engineer, discovers a way to create single crystals using metal. This is the principle behind the creation of semiconductor wafers. They are still used in electronic devices and solar cells.
1917: Albert Einstein provides a theoretic basis for photovoltaics. Einstein introduces the concept that light acts as an electromagnetic wave that is carried by a packet.
1929 Gilbert Lewis, a physicist, coined the term “photons” in 1929, to describe the electromagnetic energy of Einstein’s packets.

Age of Solar Power Growth (late-20th century)
The first commercializations of solar technology were spurred by the energy crisis in the 1970s. In the 1970s, low oil prices and slower economic development are a result of a shortage of crude oil within industrialized countries. It is the U.S. government provides financial incentives to residential and commercial solar panels, research and development institutes, demonstration projects that use solar power in government buildings as well as regulatory structures that support the current solar market. Solar panels are more affordable than ever before, starting at $1,865 per watt back in 1956 to just $106 per watt in 1976 (prices adjusted for the year 2019 dollars).
