In 1888, a Russian scientist named Aleksandr Stoletov built and patented the first true solar cell. In 1891, Baltimore inventor Clarence Kemp patented the first commercial solar water heater. In 1905, solar energy came into the global spotlight when famed physicist Albert Einstein published an article on the photoelectric effect and how light packages carry energy. The first object called a solar panel, manufactured in 1883 by the New York inventor Charles Fritts, was made by coating selenium gold, a mineral found in the ground.
While solar energy has found a dynamic and established role in today's clean energy economy, there is a long history behind photovoltaics (PV) that brought the concept of solar energy to fruition. With the way the cost of solar energy has plummeted over the past decade, it's easy to forget that solar energy had a completely different meaning even just 15 years ago. Let's go back a few centuries to the origins of solar photovoltaics and explore the history of solar energy and silicon solar technology. In theory, solar energy was used by humans as early as the 7th century a.
C. When history tells us that humans used sunlight to light fires with magnifying glass materials. Later, in the 3rd century B, C. These mirrors became a standard tool known as “burning mirrors”.
Chinese civilization documented the use of mirrors for the same purpose later in 20 A, D. In the late 1700s and 1800s, researchers and scientists managed to use sunlight to power the ovens on long journeys. They also harnessed the power of the sun to produce steamships powered by solar energy. Ultimately, it is clear that even thousands of years before the era of solar panels, the concept of manipulating the energy of the sun was a common practice.
The development of solar panel technology was iterative and required a series of contributions from several scientists. Naturally, there is some debate about when exactly they were created and to whom credit should be attributed for the invention. Some people attribute the invention of the solar cell to French scientist Edmond Becquerel, who determined that light could increase electricity generation when two metal electrodes were placed in a conductive solution. This advance, defined as the “photovoltaic effect”, influenced later photovoltaic developments with the element selenium.
In 1873, Willoughby Smith discovered that selenium had photoconductive potential, leading to the discovery by William Grylls Adams and Richard Evans Day in 1876 that selenium creates electricity when exposed to sunlight. A few years later, in 1883, Charles Fritts produced the first solar cells made of selenium wafers, which is why some historians attribute to Fritts the actual invention of solar cells.

Albert Einstein had a role to play in drawing the world's attention to solar energy and its potential. Regardless of why solar energy is interesting to you, there is a solid and fascinating story behind the rise of solar energy to a relevant state.
A year later, a solar cell with 10% efficiency was developed, but it still had little use outside of spaceflight. Until now, the contribution and experimental discoveries of several inventors and scientists had led to the creation of the modern photovoltaic (PV) solar panel. Nowadays, solar cells are used in all kinds of devices, from portable calculators to solar panels on rooftops. Aleksandr Stoletov developed the first solar cell based on the photoelectric effect at the end of the 19th century.
Then, the space and defense industries recognized its value, and at the end of the 20th century, solar energy emerged as a promising, but still costly, alternative to fossil fuels. Many argue that this event marks the true invention of photovoltaic technology because it was the first instance of a solar technology that could actually power an electrical device for several hours a day. This was a statement to make clean energy through solar energy more tangible to people and to spread awareness. While solar panel technology is relatively new, dating back about 50 years, the use of energy from the sun to maintain livelihoods began in fact several centuries ago.
This was a significant increase that allowed powering an electrical device for several hours for the first time in history. In 1953, engineer Daryl Chapin, who had previously been working on magnetic materials at Bell Labs, was trying to develop a power source for telephone systems in remote wet locations, where dry-cell batteries were degrading too quickly. . .
