Who made the solar panel
In 1839, French physicist Edmond Becquerel discovered the photovoltaic phenomenon while working with a cell comprised of metal electrodes in a conducting fluid. He discovered that the cell produced more electricity when it was exposed to light. Later in 1873, Willoughby Smith discovered that selenium might serve as a photoconductor.
Just three years later, in 1876 William Grylls Adams and Richard Evans Day used the photovoltaic principle developed by Becquerel to selenium. They recorded that it could, in fact, generate electricity when exposed to light.
Almost 50 years after the photovoltaic effect’s discovery, in 1883, American inventor Charles Fritz constructed the first operational selenium sun cell. Though we employ silicon in cells for modern, this solar cell was a crucial forerunner to the technology used today.
In a way, several physicists played a part in solar cell invention. Becquerel is associated with revealing the potential of the photovoltaic effect, and Fritz with actually developing the progenitor to all solar cells.
Awareness and manufacture of solar technologies
Albert Einstein has a role to play in calling the world’s attention to solar energy and its potential. In 1905, Einstein released a study on the photoelectric phenomenon and how light carries energy. This brought increased attention and acceptability for solar power on a broader scale.
The great stride toward solar cells like the ones used in panels today came from the work of Bell Labs in 1954. Three scientists there, Daryl Chapin, Calvin Fuller, and Gerald Pearson, constructed a more feasible solar cell utilizing silicon. Advantages to silicon are improved efficiency and its vast availability as a natural resource.
As the space age grew,s were utilized to power various elements of spacecraft throughout the late 1950s and 1960s. The first was the Vanguard I satellite in 1958, followed by Vanguard II, Explorer III, and Sputnik-3.
Throughout the 1950s, the efficiency of solar cells continued on growing, from 8 percent in 1957 to 14 percent in 1960. The space race produced a need for renewable energy sources. It steered investments and development in the solar industry. In the 1960s, the first telecommunication satellite Telstar 1 launched by Bell Labs feature the most cutting-edge solar cells.
Despite the enormous breakthroughs achieved in solar technology, it was not commercially viable yet due to its high price. As hard as it may be to believe, the early effort to cut the cost of solar came from oil firms. They realized the eventual financial difficulty of sustainable energy generation with oil. So, they started to invest in solar. Backed by Exxon, Dr. Elliott Berman designed a significantly less expensive solar cell. He got the cost per watt down by 80 percent.
Since 2008, solar power has been increasingly popular as a renewable kind of energy, since its price became affordable to a much wider market. Research and investment in solar technologies continue at an enthusiastic pace, with no shortage of engineers and innovators. Solar manufacturers continue to pursue technological breakthroughs to make solar panels more efficient and less expensive.
Solar panel manufacturing has its own environmental considerations. Solar panels have a lifetime of 25 years or more. Manufacturing of any product requires energy and resources, meaning the process inherently adds carbon dioxide to the atmosphere. There is no such thing as a free lunch when it comes to renewable energy.
