Solar power technology dates back to the 19th century. The first solar power cell was invented in 1883 by Charles Fritts. However, these early solar cells were very inefficient, converting less than 1% of the sunlight that hit them into electricity.
The Early History of Solar Power
The solar power cell technology that we use today was first developed in the 19th century. The earliest known practical solar cell was built by French physicist Alexandre Edmond Becquerel in 1839. He discovered the photovoltaic effect while experimenting with an electrolytic cell made of platinum and silver electrodes in nitric acid. His work was expanded upon by English chemist Michael Faraday, who invented the first solar cell capable of generating a current in 1876.
The first practical application of solar cells came in 1954, when American inventor Daryl Chapin, along with graduate student Gerald Pearson and engineer Chapin’s boss at Bell Telephone Laboratories, Calvin Fuller, created the first silicon solar cell. Solar cells began being used in a limited way to power small devices like calculators and watches in the 1970s. It wasn’t until the 21st century that solar power began to be used more widely to generate electricity for homes and businesses.
The First Solar Cells
Solar power cell technology was first invented in the late 19th century. The first cells were made of selenium, a material that is still used in some modern solar cells. Selenium solar cells were used in early telephones and other electronic devices. However, they were not very efficient and could only convert a small amount of sunlight into electricity. In the early 20th century, scientists began experimenting with other materials, such as silicon, that could be used to make more efficient solar cells.
The First Solar-Powered Devices
The first solar power cell was built by Charles Fritts in the 1880s. Fritts coated selenium with an extremely thin layer of gold to create a solar cell that was just 1% efficient. In 1918, Russian Constantin Chilowsky also created a selenium cell, but it wasn’t until 1954 that Bell Labs developed the silicon solar cell, which is the type of cell used in most solar panels today.
The First Solar Array
The first solar array was built in New York City in 1884. It was made up of 144 selenium cells and was used to power two electric fans.
The First Solar Power Plant
The world’s first solar power plant was built in 1884 by Charles Tellier in Maubeuge, France. Solar power cells were used to power the plant, which produced ice for a local brewery. The cells were later replaced with coal-fired generators.
In 1898, Augustin Mouchot and Paul Camille Populus demonstrated a solar-powered engine at the World’s Fair in Paris. The engine used a parabolic reflector to concentrate sunlight onto a steam-generating tube.
The first practical solar cell was developed in 1947 by Russell Ohl. His design used silicon as the semiconductor material and had an efficiency of 6%.
The First Solar-Powered Home
In 1839, French physicist Antoine César Becquerel discovered the photovoltaic effect while experimenting with a solid electrolyte in an electrochemical cell. Becquerel’s experiments led others to study the potential of using the photovoltaic effect to generate electricity. In 1876, William Grylls Adams and Richard Evans Day discovered that selenium could be used to create electricity when exposed to light. Selenium was later replaced by silicon as the material of choice for solar cells.
The first solar-powered home was built in 1898 by American inventor Clarence Kemp. Kemp’s home had a roof covered with 485 selenium cells, which were used to power two DC electric lights and a fan. In 1954, Bell Labs created the first silicon solar cell, which was capable of converting 6% of the sunlight it absorbed into electricity.
The efficiency of solar cells has increased significantly since then, with modern cells capable of converting up to 40% of the sunlight they absorb into electricity. Solar power is now used extensively for a variety of applications, including powering homes and businesses, providing electricity for electric vehicles, and generating electricity for the grid.
The First Solar-Powered Car
The first solar-powered car was invented in 1888 by French electronics engineer Augustin Mouchot. The car was powered by a steam engine and used parabolic mirrors to focus and magnify the sun’s rays to generate heat. Mouchot’s invention was later exhibited at the Paris Exposition of 1878, where it won a bronze medal.
The First Solar-Powered Aircraft
The technology for solar-powered aircraft was first developed in the 1970s. The idea for using solar energy to power an aircraft came from the work of two scientists, Freak and Kaufman. They proposed using large solar arrays to power electric motors. The first solar-powered aircraft was built in 1974 by Aerospace engineer Paul MacCready. It was called the Gossamer Penguin and it had a wingspan of 100 feet (30 meters). It was powered by 2680 solar cells and flew for only 72 seconds.
The Future of Solar Power
The first solar power cell was built in 1883 by Charles Fritts, but the efficiency of these early cells was so low that they were only used for powering small electrical devices. In 1941, Russell Ohl patented the junction semiconductor photovoltaic cell, which increased the efficiency of solar cells by allowing them to convert more sunlight into electricity.
The availability of cheap silicon in the 1950s and 1960s led to the mass production of solar cells, which brought down their cost and made them more affordable for consumers. In the 1970s, oil crises and concerns about energy independence led to an increase in investment in solar power, and by the end of the decade, photovoltaic cells were being used to power everything from calculators to spacecraft.
In the 1980s and 1990s, advances in materials science and manufacturing technology resulted in further increases in efficiency and reductions in cost. Today, solar power is one of the fastest-growing sources of energy in the world, with countries like China and India investing heavily in large-scale solar farms.
