The Birth of Solar Energy: Edmond Becquerel’s Groundbreaking Discovery

The story of solar energy starts in 1839. A French physicist, Edmond Becquerel, was working in his father’s lab. He discovered that certain materials could make electric current from sunlight. This is what we call the photovoltaic effect or the Becquerel effect.

The Photovoltaic Effect

The key finding was that some materials, like silver chloride and selenium, could create electricity from light. This was a big step for solar energy and the invention of electrochemical cells.

Becquerel’s Electrochemical Cell

Becquerel showed his discovery by making an electrochemical cell. He used two plates, one platinum and one gold, in a liquid. The liquid could be acidic, neutral, or alkaline. When hit by sunlight, this setup could make a little electricity. This was the first move towards today’s solar technology.

Even though Becquerel’s cell didn’t work very efficiently, his idea started the progress in solar energy. His work led to many improvements in making use of the sun for power.

Early Pioneers and Innovators

In the early days of solar energy, several key figures stood out. In 1873, Willoughby Smith noted that selenium acted well with sunlight. This was a key step forward for solar cell pioneers and photovoltaic technology development.

Willoughby Smith and the Selenium Photoconductor

Smith’s discovery about selenium in 1873 was a game-changer. He found that it could turn light into electricity. This sparked the development of the first solid-state solar cell.

Charles Fritts and the First Solid-State Solar Cell

In 1881, Charles Fritts built on Smith’s work. He crafted the first solid-state solar cell by covering selenium with gold. Though its efficiency was just 1%, it was a major step in solar tech’s evolution.

Russell S. Ohl was an American engineer. He was also a notable research on semiconductors. Ohl is a key figure in the creation of today’s solar technology. His work with P-N junctions and semiconductors led to inventions like the transistor, LEDs, and laser diodes.

Russell S. Ohl and the Silicon Solar Cell

In 1839, Ohl found the P-N junction. This junction has a positive and negative side in a single crystal semiconductor. Then, in 1841, he made the first silicon solar cell. His design is still used today in solar PV panels. Ohl’s work was a major step in the birth of modern photovoltaic technology.

The Advent of Modern Photovoltaic Technology

Ohl’s early work in semiconductors set the stage for modern solar tech. By inventing the first silicon solar cell, he started a new energy era. His breakthroughs created a path for others. These pioneers would push forward the solar energy revolution.

Commercialization and Breakthroughs

Solar energy’s commercial journey started many years ago. It was pioneered by early thinkers such as Charles Fritts. In 1883, Fritts made the first selenium solar cell that worked. This marked a big step in the solar array technology’s growth. He then set up the first solar array on a New York City rooftop, showing off solar power’s promise.

Famed physicist Albert Einstein helped push solar energy forward. In 1905, he wrote a key paper on the photoelectric effect. This paper showed how light can carry energy and make electricity. It was a turning point for solar technology.

In 1954, Bell Labs made a major move by creating the first practical solar cell. Though it was not very efficient and was costly, their achievement was huge. It gestured to a future of solar energy commercialization and solar technology breakthroughs. Today, we are living in that future thanks to their work.

The Solar Energy Revolution

In the 1970s, people started to care more about the environment. This pushed the need for new, cleaner energy sources. The U.S. government helped a lot by passing the Solar Energy Research, Development and Demonstration Act of 1974. They gave out grants and tax breaks to help solar energy grow.

Rising Awareness and Government Support

The world was beginning to notice environmental problems. This made governments think about new, clean energy. In 1974, the U.S. made a big move by creating the Solar Energy Research, Development and Demonstration Act. It gave a lot of money and support to make solar power better and more popular.

Technological Advancements and Cost Reductions

Over the years, solar technology got much better. Silicon solar cells became more efficient, making solar power stronger. Prices for solar panels dropped, making it easier for homes and businesses to use solar power. All these things, along with government help, spurred a big change towards solar energy.


The history of solar energy is filled with pioneers. These are scientists, inventors, and innovators. They built the foundation for today’s renewable energy revolution. Edmond Becquerel discovered the photovoltaic effect. This led to the creation of efficient solar cells we have today.

Now, solar power is a practical and accessible energy source. It is thanks to increasing awareness, government support, and tech upgrades. This shift to clean energy is crucial worldwide.

Fenice Energy has over 20 years in providing solar and other clean energy solutions. The world is moving towards renewable energy swiftly. The future for solar energy looks very promising.

The rise of solar power marks a journey of key findings, innovation, and strong commitment. It meets the global need for eco-friendly power. The solar industry will keep playing a key role, making our energy cleaner and more reliable, helping communities and businesses with renewable energy options in India and beyond.
