Who Introduced Solar Energy
In 1939, Russell Ohl created the solar cell design used in many modern solar panels. He patented his design in 1941. In 1954, this design was first used by Bell Labs to create the first commercially viable silicon solar cell.
Who discovered solar energy?
In 1839, the ability of some materials to create an electric charge from light exposure was first observed by Alexandre-Edmond Becquerel. Although these first solar panels were too inefficient for even simple electrical devices, they were used as an instrument to measure light.
Who is the father of solar energy?
How Einsteins theory of the photoelectric effect changed the world. Solar energy is considered the energy source of the future.
Invention Of The Solar Cell: Bell Labs Makes A Huge Discovery
The real beginning of the modern solar panel started with Gerald Pearson, a physicist at Bell Laboratories. In the spring of 1953, he was experimenting with silicon, one of the most abundant elements in the universe, for use in electronics when he inadvertently discovered that he could create a much more efficient solar cell using silicon instead of the selenium traditionally used in harvesting solar energy.
Two of his colleagues, seeing the importance of this discovery, quickly created the first solar cell efficient enough to power small electronics. With this, the modern solar panel was born.
However, the solar cells low efficiency and extremely high cost made this new technology out of reach for large applications, and interest was only from toy and radio makers, who put the cells in toy boats, beach radios, and model airplanes.
Seemingly doomed to powering unnecessary trinkets, one creative application was about to come along that would propel the solar panel in front of the entire world.
What Is Solar Panel
Today we would like to talk about who invented solar panels. But firstly let us have an idea of solar panels. The term solar panel is used colloquially for a photo-voltaic module.
A PV module is an assembly of photo-voltaic cells mounted in a framework for installation. Photo-voltaic cells use sunlight as a source of energy and generate direct current electricity. A collection of PV modules is called a PV Panel, and a system of Panels is an Array. Arrays of a photovoltaic system supply solar electricity to electrical equipment.
The most common application of solar energy collection outside agriculture is solar water heating systems and solar power plant systems. Now let us talk about who invented solar panels.
When the solar cell was invented, it set a change in motion for energy production. This change would iterate over hundreds of years in the hands of various physicists and engineers. The history of solar energy is a fascinating story of innovation and progress.

Impact On Electricity Network
With the increasing levels of rooftop photovoltaic systems, the energy flow becomes 2-way. When there is more local generation than consumption, electricity is exported to the grid. However, an electricity network traditionally is not designed to deal with the 2- way energy transfer. Therefore, some technical issues may occur. For example, in Queensland Australia, more than 30% of households used rooftop PV by the end of 2017. The duck curve appeared often for a lot of communities from 2015 onwards. An over-voltage issue may result as the electricity flows from PV households back to the network. There are solutions to manage the over voltage issue, such as regulating PV inverter power factor, new voltage and energy control equipment at the electricity distributor level, re-conducting the electricity wires, demand side management, etc. There are often limitations and costs related to these solutions.
When electric networks are down, such as during the October 2019 California power shutoff, solar panels are often insufficient to fully provide power to a house or other structure, because they are designed to supply power to the grid, not directly to homes.
From Powering Space Satellites To A Million Dollar Industry
However, Fritts’ selenium cells did find other applications, as they were used as light sensors to control the exposure time of cameras and even eventually served to power space satellites of all kinds, a market for which the cost of selenium was no obstacle.
These days, Fritts’ dream has become a multi-billion-dollar industry that, according to figures from the World Bank, is key to providing power to 840 million people currently without access to electricity. Technological advances have also made it possible to achieve an efficiency of up to 24% in some solar cell models, making this energy source not only an essential technology for achieving sustainability, but also the great promise for guaranteeing universal access to electrical energy, almost 150 years after the first light bulb was switched on.

How Old Is Solar
Although solar energy as we know it is no more than 60 years old, the discoveries that led to the solar cell began almost 200 years ago. These discoveries about the properties and conductivity of light have made solar energy what it is today.
How long has life been on Earth?
The oldest known fossils are about 3.5 billion years old, but some scientists have discovered chemical evidence to suggest that life may have begun even earlier, nearly 4 billion years ago.
How do we know Earth is 4.5 billion years old?
All data from Earth and beyond have led to an estimated age of 4.5 billion years for our planet. The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample.
Who Created The First Solar Panel
The first solar cell was created by American Charles Fritts in 1883. He fabricated the first solar cell from thin sheets of selenium covered with a thin layer of gold. Although Fritts device had an energy conversion efficiency of about 1%, his invention was the greatest milestone in the development of the solar cell technology.
The development of the silicon solar cell had to wait for more than 50 years, until the development of the p-n junction in the early 1940s. The solar cell developed the highest efficiencies of 6-10% by the 1950s.
However, it was in the 1970s that the process of commercializing the photovoltaic cells began, and the first commercial solar cell was produced by the RCA Corporation in 1953.

From Solar Cell To Solar Panel
The solar cells are soldered together, using metal connectors to link the cells. Solar panels are made of solar cells integrated together in a matrix-like structure.
The current standard offering in the market are:
-
48 cell panels – suitable for small residential roofs.
-
60-cell panels – this is the standard size.
-
72-cell panels -used for large-scale installations.
The most common sized system in terms of kWh for UK homes is the 4kWh solar system.
After the cells are put together, a thin layer of glass is added on the front side, facing the sun. The backsheet is made from highly durable, polymer-based material. This will prevent water, soil, and other materials from entering the panel from the back. Subsequently, the junction box is added, in order to enable connections inside the module.
It all comes together once the frame is assembled. The frame will also provide protection against impact and weather. The use of a frame will also allow the mounting of the panel in a variety of ways, for example with mounting clamps.
EVA is the glue that binds everything together. It is very important that the quality of the encapsulant is high so it doesn’t damage the cells under harsh weather conditions.
History And Creation Of Solar Panels How Did It All Begin
Its indisputable that the invention of solar cells changed the course of history. With solar technology, we were given an alternative to fossil fuels and a chance to make up with our planet, to redeem ourselves for all the bad we did in the past.

Final Remarks On The Origin Of Solar Panels
As youve seen, solar power is nothing new. Even the ancient peoples used it for heat, fire, and light. They probably didnt have a clue just how beloved the same energy would be many centuries later.
But the world saw the first ancestors of todays solar panels only in the 1800s. They were the inventions of French, German, and Russian scientists. These machines paved the way for the solar constructions you use today.
Still, one of the biggest breakthroughs in the history of solar panels wouldnt have happened without Russel Ohl. His use of silicon in 1941 led to the most modern solar-powered constructions.
When Was Solar Energy First Used
In theory, solar energy was used by humans as early as 7th century B.C. when history tells us that humans used sunlight to light fires with magnifying glass materials. Later, in 3rd century B.C., the Greeks and Romans were known to harness solar power with mirrors to light torches for religious ceremonies. These mirrors became a normalized tool referred to as burning mirrors. Chinese civilization documented the use of mirrors for the same purpose later in 20 A.D.
Another early use for solar energy that is still popular today was the concept of sunrooms in buildings. These sunrooms used massive windows to direct sunlight into one concentrated area. Some of the iconic Roman bathhouses, typically those situated on the south-facing side of buildings, were sunrooms. Later in the 1200s A.D., ancestors to the Pueblo Native Americans known as the Anasazi situated themselves in south-facing abodes on cliffs to capture the suns warmth during cold winter months.
In the late 1700s and 1800s, researchers and scientists had success using sunlight to power ovens for long voyages. They also harnessed the power of the sun to produce solar-powered steamboats. Ultimately, its clear that even thousands of years before the era of solar panels, the concept of manipulating the power of the sun was a common practice.

Further History Of Solar Cells
When it comes to the world actually knowing about solar energy and its benefits, the famous Albert Einstein played a huge role in that. In 1905 this scientist published a paper where he explained how light could create energy and what is a photoelectric effect. This paper of his made the world accept this new invention.
Then, again 50 years later, three scientists Calvin Fuller, Daryl Chapin and Gerald Pearson, who all were working in Bell Labs, made a huge step forward by designing the silicon solar cell we use today in solar panels. The benefits were huge silicon based cells were far more effective and very available as a natural resource.
After that, the ball continued to roll. During the 1960s, solar cells were used for creating some parts of spacecraft, like for the satellite Vanguard I, Sputnik 3, Vanguard II, and Explorer III. But just a few years later, more precisely in 1964, NASA launched a satellite that was completely based on an array of 470-watt photovoltaic solar panels.
How Did Solar Panels Change The World
Solar panels have changed the world by providing a source of renewable energy, increasing energy independence, and reducing climate change. By converting solar energy into electricity, solar panels have allowed people to generate their own electricity and reduce dependence on traditional energy sources.
Additionally, solar energy is a form of clean energy, meaning that it does not emit carbon dioxide or other pollutants and therefore can help to reduce climate change. Solar panels have become increasingly affordable and accessible, and as a result, more and more people are turning to this form of renewable energy to help them save money, reduce their environmental footprint, and increase their energy independence.
As more people switch to solar, the cost of solar panels has become increasingly competitive and more countries and businesses are encouraging their citizens to adopt solar technology. Solar panels are transforming the way we think about, access, and use energy, and in turn, this has allowed us to create a more sustainable and energy efficient future.

Solar Panels In Astronautics & Aviation
In 1968, solar panels were introduced in the Gemini 11 and 12 space missions. The panels drew power from the sun during different times of the day, enabling the spacecraft to remain in orbit for an additional 3 days.
In the late 60s and early 70s, panels were used in space probes that landed on the moon and its satellites.
Planetary exploration was not the only use for solar panels. In 1970, the worlds first solar power station was opened. The 50-kilowatt plant was built in New Mexico and was capable of heating water for 800 homes.
Solar Power In Antiquity
Humans have always recognized the power of the sun, and even early humans found ways to capture the suns energy and use it for their benefit. The earliest known use of solar power was in the 7th century BC, when humans used magnifying glasses to concentrate the suns rays to start fires. Later on, the Greeks and Romans used concentrating mirrors to light torches. The Greeks even had an experimental death ray, which used concentrated sunlight to set fire to enemy ships.
Horace de Saussure created the first known solar collector in 1767. It consisted of a series of glass boxes placed inside one another. When exposed to direct sunlight, temperatures in the inner-most box would heat up to over 100 degrees Celcius. His invention was successfully used as a solar cooker by Sir John Herschel during his expedition to South Africa.
