When Solar Energy was invented?
When Solar Energy was invented?
The history of solar power began in 1954 with a few small steps, led by inventors and scientists. The 20th century was when{,|| it was the time that} the defense and space industries realized the potential of solar energy. At the time it was an attractive however, it was still a costly alternative to fossil fuels. The technology has advanced and is now a viable and affordable technology that is rapidly replacing coal, oil, and natural gas in the present energy market. This timeline will highlight the major pioneers and events that led to the development of solar technology.
The Age of Discovery (19th-20th century)
The 19th century was the beginning of physics thanks to discoveries in magnetism, electricity as well as the research of light. Scientists and inventors laid the foundation for the majority of the development in the field 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 subsequent developments in photovoltaics. In the European Photovoltaic Sun Energy Conference and Exhibition award the Becquerel award each year.
1861: Auguste (or Augustin) Mathematician and physicist patents the solar motor.
1873: Willoughby Smith, an electrical engineer discovers the photovoltaic effects in 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 either from light or heat reaction. “2
1882: Abel Pifre creates a “solar engine”, which generates enough electricity to power the solar printer. (pictured below)
The year is 1883. Charles Fritts, an inventor, designs the first solar cell using the elements of gold and selenium. It converts solar radiation into electricity at a mere one percent efficiency.
1883: John Ericsson, an inventor, creates the sun motor, which uses the construction of parabolic tubes (PTC) to focus solar radiation to power a boiler steam. PTC continues to be utilized for solar power generation.
1884: Charles Fritts places solar panels on the roof of a New York City rooftop.
1903: Aubrey Eneas, a Pasadena-based entrepreneur, starts The Solar Motor Company to market solar-powered steam engines for irrigation projects. The company soon fails.

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 provides the mechanism through which packets of light can alter the electrons in silicon crystals and create electrical currents.

1916. Jan Czochralski, a chemist, invents a way to make single crystals out of metal. This is the principle behind making semiconductor wafers that remain in use in electronics or solar cells.
1917. Albert Einstein provides a theoretic basis for photovoltaics. Einstein introduces the concept that light is an electromagnetic force-carrying packet.

The Age of Solar Power Growth (late-20th century)
Solar technology’s first introductions to commercialization were spurred through the economic crisis of the 1970s. In the 1970s, low oil prices and slow economic growth are the result of a shortage of petroleum in industrialized countries. The U.S. government provides financial incentives for commercial and residential solar panels as well as 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 currently cheaper than ever, from $1,865 per watt back in 1956 to $106 per watt in 1976 (prices are adjusted to reflect the year 2019 dollars).
