When Solar Energy was invented?
The year that Solar Energy was invented?
The history of solar power began in 1954 with a couple of small steps, driven by scientists and inventors. The 20th century was when{,|| it was the time that} the space and defense industries realized the value of solar energy. At the time it was an attractive but expensive alternative to fossil fuels. The field has grown and is becoming a viable and cost-effective technology that is quickly replacing coal, oil, as well as natural gas, in 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 mid-19th century saw the beginning of physics, with discoveries in electricity, magnetism along with the science of light. Researchers and scientists laid the foundation for the majority of the development of solar energy.
1839: 19-year-old Frenchman Alexandre-Edmond Bécquerel designs one of the first solar cells in the world.1 His researches on electricity and light influenced the development of photovoltaics in the following years. It is the European Photovoltaic Sun Energy Conference and Exhibition awards the Becquerel prize each year.
1861 Auguste (or Augustin) Mathematician and physicist, invents the solar motor.
1873: Willoughby Smith, an electrical engineer, discovers photovoltaic effects in selenium.
1876: W. G. Adams (professor of Natural Philosophy, King’s College London) discovers that the electrical resistance of selenium may change due to radiation heat, light or chemical reaction. “2
The year is 1882. Abel Pifre creates a “solar engine” which produces enough power to power its solar-powered printing presses. (pictured below)
The year is 1883. Charles Fritts, an inventor, creates the first solar cell using the elements of gold and selenium. The cells convert solar radiation into electricity with a mere 1percent efficiency.
1883: John Ericsson, an inventor, creates the sun motor, which uses the construction of parabolic tubes (PTC) to concentrate solar radiation to power a boiler steam. PTC is still utilized 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 to improve our understanding of the photovoltaic electricity. Quantum Physics’ description of the subatomic worlds of electrons and photons shows the way in which packets of light can cause electrons to be sucked out of silicon crystals and create electrical currents.
The year was 1888. Wilhelm Hallwachs, a scientist, describes the physics behind photovoltaic cells. This is the basis of what we call”the” Hallwachs Effect.
1905: Albert Einstein publishes, “On an Heuristic Perspective on the Production of Light and the Transformation of Light,” explaining how light produces an electrical current through knocking electrons from certain metal atoms.
1916. Jan Czochralski, a scientist, comes up with a method to create single crystals from metal. This is the basis of making semiconductor wafers that are still used in electronic devices and solar cells.
1917: Albert Einstein provides a theoretical basis for photovoltaics. He introduces the idea that light acts as a packet carrying electromagnetic force.
1929: Gilbert Lewis, a scientist and physicist, invented”photons” in 1929 “photons”, to describe the electromagnetic energy of Einstein’s packets.
Age of Solar Technology Development (mid-20th Century)
The lab has become no more the ideal place to conduct serious research into the development of solar energy technology, based on the discovery the monocrystalline silicon-based cells.

Age of Solar Power Growth (late-20th century)
First commercializations in solar technologies were brought on by the energy crisis of the 1970s. In the 1970s, low oil prices and slower economic development are the consequence of a lack of petroleum in industrialized nations. 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 being regulatory structures to support the current solar market. Solar panels are now cheaper than ever, from $1,865 for a watt in 1956 to just $106 per watt in 1976 (prices adjusted for 2019 dollars).
