Are you an Earth lover who wants to do your part to keep our planet clean and green?

If so, you're a prime candidate for switching to solar power to use at home. Once this process goes into effect, it's set to change the world.

But who invented solar panels? Check out our guide below to learn more about the inventor of solar panels and their history.

Early Days of Solar Energy

The use of solar energy can be traced back to ancient civilizations such as the Greeks, Romans, and Chinese. They used solar energy for various purposes, including heating homes and water, drying crops, and cooking food. The ancient Greeks even designed their homes and public buildings to take advantage of the sun's warmth and light.

In the 18th century, Swiss scientist Horace-Benedict de Saussure invented the first solar oven. This oven used mirrors to focus sunlight and cook food. This invention was the first step towards harnessing the sun's energy for practical purposes.

In the 19th century, scientists began to experiment with photovoltaic cells. These cells convert sunlight into electricity.

In addition to Alexandre Edmond Becquerel's discovery of the photovoltaic effect, British scientist William Grylls Adams and his student Richard Day observed that selenium produced an electric current when exposed to light. This discovery led to the development of the first selenium solar cell by Charles Fritts.

Charles Fritts and the First Solar Cell

The first solar cell was invented in 1883 by American inventor Charles Fritts. It was made using a thin layer of selenium coated with a layer of gold. The device was inefficient, with a 1-2% conversion rate.

Fritts' selenium cell worked on the principle of the photovoltaic effect. This effect was first discovered by Alexandre Edmond Becquerel in 1839.

The photovoltaic effect is where certain solar panel materials produce an electric current when exposed to sunlight. In the selenium cell, sunlight was absorbed by the selenium layer. This causes electrons to be freed from their atoms and creates a flow of electric current.

Although Fritts' cell was not very practical, it was a necessary proof of concept that paved the way for developing more efficient solar cells. In the decades that followed, scientists and engineers continued to experiment with different materials and designs to improve the efficiency of solar cells.

Improvements in Solar Cell Technology

One of the significant breakthroughs in solar cell technology came in the 1950s. It was when scientists at Bell Labs in the United States began experimenting with silicon. They found silicon was much more efficient for solar cells than selenium or other materials.

Daryl Chapin, Gerald Pearson, and Calvin Fuller invented the first solar cell. It has a conversion rate of 6%.

The silicon solar cell was much more efficient than previous designs and could be produced on a larger scale. This makes it practical for use in a wide range of applications.

Solar cells became smaller, lighter, and more affordable in the following years. This leads to the widespread use of solar energy for space and terrestrial applications.

In the 1970s, the oil crisis led to a renewed interest in solar energy. Governments and private companies looked for alternative sources of energy.

They tried to find alternatives that were not dependent on fossil fuels. This led to increased research and development in solar cell technology. This results in further improvements in efficiency and affordability.

Modern Solar Panels

Today, solar panels are a common sight in many parts of the world. Individuals and businesses look for ways to reduce their reliance on fossil fuels and cut their carbon footprint.

Solar panels are made using a variety of materials. This includes silicon and thin-film photovoltaic cells. These cells are made of cadmium telluride, copper indium gallium selenide, and organic materials.

Modern solar panels are much more efficient than early designs, with conversion rates exceeding 20%. They are also much more affordable, thanks to advances in manufacturing technology and economies of scale.

Solar panels are now used for various applications, from powering individual homes and businesses to large-scale solar power plants that generate electricity for entire communities. They are also designed to work in all kinds of weather, from hot and sunny to cold and cloudy.

Another advantage of modern solar panels is that they are easier to install. They can be mounted on rooftops, on the ground, or even on walls. And because they don't need any fuel or moving parts, they require very little maintenance.

Overall, modern solar panels are essential to the fight against climate change. They are clean, renewable, and getting cheaper all the time. As more and more people switch to solar power, we can reduce our reliance on fossil fuels and create a cleaner, greener future for ourselves and our planet.

Who Can Be Considered the Inventor of Solar Panels?

If you're wondering who invented solar panels, it was a collaborative effort that involved many people over several decades. While Charles Fritts is often credited with inventing the first solar cell, it is essential to recognize the contributions of others who helped to develop and improve the technology over time.

For example, the development of the silicon solar cell by Daryl Chapin, Calvin Fuller, and Gerald Pearson in the 1950s. It was a significant breakthrough that paved the way for the modern solar panels we see today.

Similarly, the work of scientists such as Alexandre Edmond Becquerel and William Grylls Adams. Their work laid the groundwork for discovering the photovoltaic effect and developing early solar cells.

Now You Know Who Invented Solar Panels

The invention of solar panels has changed the future of energy harvesting and efficient energy solutions for homes and businesses worldwide. Thanks to those who invented solar panels.
