Solar Energy in Antiquity: Early Beginnings

Solar energy’s history goes back many centuries, with hints of use in old times. By the 7th century B.C., people used the sun to start fires with glass. In the 3rd century B.C., the Greeks and Romans advanced, using mirrors to light torches for their rituals. They even had a name for it: “burning mirrors.”

Solar Passive Designs and Magnification

Sunrooms, places that use sunlight, were very early forms of using solar power. The Romans created bathhouses like this, built on sunny sides of buildings. In the 1200s A.D., the Anasazi, ancestors of the Pueblo people, designed homes to catch the sun for warmth in the winter.

Sunrooms and Warmth Capture

Eventually, people moved from these simple designs to using solar power in machines. In the late 1700s and 1800s, inventors started to create ovens and steamboats that ran on the sun’s power. This showed how diverse and useful solar power could be.

Solar-Powered Ovens and Steamboats

This journey through solar energy started in old times with basic uses. From sunrooms to ovens and boats, every step set the stage for modern solar power. Fenice Energy, a leader in the clean energy field with 20 years of experience, is helping bring solar to more places, like India.

The Discovery of the Photovoltaic Effect

Solar panel tech grew over time with many scientists’ help. Edmond Becquerel of France might have found the solar cell in the 1800s. He saw that light could make electricity when certain metals were in a conducting mix. This “photovoltaic effect” was key for solar panel progress, especially using selenium.

Edmond Becquerel’s Pioneering Work

In 1839, Edmond Becquerel’s research set the stage for solar cells. He found that light could make some materials produce electricity. This started the journey to making solar energy a reality.

Selenium’s Photoconductive Properties

By 1873, Willoughby Smith knew selenium could turn light into electricity. Then, in 1876, William Grylls Adams and Richard Evans Day confirmed this. They showed selenium could generate electricity from the sun. This added to our knowledge of how solar cells work.

Charles Fritts’ Solar Cells

In 1883, Charles Fritts made the first solar cells from selenium. You could say he invented solar cells. His achievement marked a big step towards using the photovoltaic effect practically.

what is the history of solar energy: The Silicon Photovoltaic Revolution

Solar cells today mostly use silicon, not selenium. The creation of the first silicon-based solar cell in 1954 is key. Daryl Chapin, Calvin Fuller, and Gerald Pearson at Bell Labs made this breakthrough. The first silicon solar cell was not very efficient, working at four percent. But it laid the foundation for the efficient cells we have today.

Russell Ohl’s P-N Junction Discovery

In 1940, Russell Shoemaker Ohl found the p-n junction at Bell Labs. This is crucial for solar cells. His discovery set the stage for future advancements in silicon solar cells.

Bell Labs’ First Practical Solar Cell

The team at Bell Labs led by Daryl Chapin, Calvin Fuller, and Gerald Pearson created something big in 1954. They developed the first silicon photovoltaic (PV) cell that was practical. This creation was a turning point. It started what we now know as the silicon photovoltaic revolution.

Solar Energy Milestones and Achievements

Solar energy’s progress has had many notable moments. These have helped it become a key player in the clean energy world. It all started in space and moved on to power our homes. This growth showcases our ability to find new solutions and develop them over time.

Solar Power in Space Exploration

Space tech was the first to use solar power. This journey began with Vanguard I in 1958. It had a one-watt panel for its radios. This was just the start. Soon, more satellites, like Vanguard II and Explorer III, joined in. Exploring space is hard work, but these early solar systems made it a bit easier.

NASA didn’t stop there. In 1964, it launched the first fully solar-powered spacecraft, Nimbus. Then, in 1966, it sent a solar-powered telescope, the Orbiting Astronomical Observatory, to space. These missions showed that solar energy could power big, important projects.

First Solar-Powered Residence

The University of Delaware built “Solar One” in 1973. This was a big moment for solar power. Their project showed that the sun could provide energy for all kinds of buildings. It opened the door for more solar homes and businesses in the future.

Breakthroughs in Solar Conversion Efficiency

The power we can get from solar cells has come a long way. In the late 1950s, Hoffman Electronics boosted efficiency from 8% to 14%. Then, the University of South Wales pushed it even further. By 2016, they reached a whopping 34.5% efficiency! This progress means we get more energy from the sun than ever before.

Solar-Powered Aviation

In 1981, Paul MacCready designed the Solar Challenger. This was the first plane powered only by the sun. It made a big statement about solar power’s potential in transportation. Such innovations led to the development of more advanced solar aircraft and vehicles.

Presidential Solar Initiatives

Political leaders have also shaped the path of solar energy. President Jimmy Carter set up solar panels at the White House in 1979. This was a strong message about the need for green energy. But then President Reagan took them down. This move highlights the ups and downs of government support for solar over the years.

Plummeting Costs of Solar Panels

The cost of solar panels has dropped significantly. In 1956, a panel cost INR 300 per watt. Now, in our time, it’s only INR 0.50 per watt. This price change has made solar energy more doable for everyone. This marks a huge step forward in making our energy sources cleaner and cheaper.
