The Pioneering Discoveries That Paved the Way

The journey of solar cells starts in 1839. The French physicist Edmond Becquerel noted something interesting. He saw that light could create small electric currents in certain materials. This happening was called the photovoltaic effect.

Edmond Becquerel’s Photovoltaic Effect (1839)

In 1873, Willoughby Smith found that selenium could conduct electricity when exposed to light. He was testing this for cables underwater. Later, in 1883, Charles Fritts made the very first solar cell. It was made by putting gold on selenium. This first solar cell could only change 1% of light into electricity.

Willoughby Smith’s Photoconductivity of Selenium (1873)

The early studies of the photovoltaic effect and photoconductivity led to the first solar cell. The discovery of these effects opened the door to the solar power technology we know today.

Charles Fritts’ First Solar Cell (1883)

Though not very efficient, Fritts’ solar cell was a huge step forward. It was the start of better solar cells. His work began a journey towards creating more efficient solar cells in the future.

Early Solar Cell Research and Development

In the early 1900s, major steps were taken in solar cell research. In 1905, Albert Einstein’s paper on light’s quantum theory and the photoelectric effect was groundbreaking. He won the Nobel Prize in Physics in 1921 for this work. It set the stage for further studies on how solar cells work.

Russell Ohl’s Discovery of the P-N Junction (1940)

Russell Shoemaker Ohl made a significant breakthrough in 1940. He was at Bell Labs working on semiconductors when he discovered the p-n junction. This discovery is the core of a solar cell’s design. Ohl found that current passed through a cracked silicon sample. This highlighted where the positive and negative sides met, forming the p-n junction.

These early studies paved the way for modern solar cell technology. They laid a strong foundation for today’s efficient and practical solar cells.

When Was the Solar Cell Invented?

In 1954, a team at Bell Labs in the U.S. created the first practical silicon solar cell. Engineer Daryl Chapin, chemist Calvin Fuller, and physicist Gerald Pearson worked on it. They managed to make a cell that converted sunlight into electricity at a 6% rate, better than before.

The Bell Labs Silicon Solar Cell (1954)

This group of scientists worked hard for months to overcome challenges in making the solar cells. They focused on creating good electrical connections and stabilizing the p-n junction. Their achievement led to the creation of a “solar battery,” which they showed in April 1954. This was a key moment that started the age of silicon solar technology we know today.

Daryl Chapin, Calvin Fuller, and Gerald Pearson’s Breakthrough

Chapin, Fuller, and Pearson’s work was pivotal in the silicon solar cell’s history. Their commitment to improving the solar cells’ efficiency and reliability laid the groundwork for solar power’s future progress. Their work marks a crucial step in the advancement of renewable energy.

Solar Cells in Space Exploration

In the late 1950s, solar cells started getting attention for space use. They appeared on the Vanguard I satellite. This was launched in 1958. The satellite was the first to rely on solar cells for power, instead of just batteries. This move showed solar power’s value for space missions.

Explorer 6 and Solar Arrays in Satellites

The year 1959 saw the launch of the Explorer 6 satellite by the U.S. It was special because it had big solar panels shaped like wings. These panels had 9,600 Hoffman solar cells. With this launch, solar power use in space took a big step forward.

By the 1960s, solar cells had taken over as the main power source for many satellites. Also, they powered several probes into our solar system. They were chosen because they produce a lot of power for their size. As the need for more efficient cells grew, researchers turned to new materials. Gallium arsenide started to replace silicon in the solar cell world.

Advancements in Solar Cell Technology

In the past decades, solar cell technology has grown a lot. It aims to make solar power more efficient and less expensive. Dr. Elliot Berman from the 1970s developed a low-cost solar cell. This innovation cut the cost per watt from INR 7,000 to INR 1,400.

In the 1980s and 1990s, research teams at several universities and the NREL also made big steps. They topped 20% and even hit 30% solar cell efficiency. Those achievements were big moments for solar cell technology.

Thin-Film and Multi-Junction Solar Cells

Thin-film and multi-junction solar cells are newer types that have helped a lot. They use materials such as cadmium telluride, copper indium gallium selenide, and amorphous silicon. This makes them cheaper than the standard silicon cells but with good performance.

Multi-junction solar cells stand out for their high efficiency over 30%. They do well in places where solar power is very concentrated, like in big solar power plants.
