The history of solar cells can be traced back to an early observation of the photovoltaic effect in 1839.Although solar energy has found a dynamic and established role in today's clean energy economy, there is a long history behind photovoltaic (PV) energy 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.

The first modern solar panels, with an efficiency still low of 4%, were developed by three researchers from Bell Laboratories, Daryl Chapin, Gerald Pearson and Calvin Fuller. Today, the Becquerel Prize is presented annually by the European Photovoltaic Solar Energy Conference and Exhibition. With new developments, solar energy became the accepted source of energy for space applications and remains so today.
As the space age developed, solar panels were used to power various parts of spacecraft in the late 1950s and 1960s. Becquerel is credited with discovering the potential of the photovoltaic effect, and Fritz is credited with creating the ancestor of all solar cells. The government creates financial incentives for commercial and residential solar systems, research and development institutes, demonstration projects for the use of solar electricity in government buildings and a regulatory structure that still supports the solar industry today. So where is the balance? Today, companies are striving to achieve a more attractive and advanced solar technology, such as photovoltaics applied to construction (BAPV).
In 1977, the United States adopted the development of solar energy by creating the Solar Energy Research Institute. With this discovery, the scientific world discovered everything necessary to develop modern solar technology. But over the next few decades, the federal government was more involved in solar energy research and development, creating subsidies and tax incentives for those who used solar systems. As the invention was introduced, it made solar cells a prominent use for satellite power generation.
As solar panels are built to be more efficient and cost less, solar energy has become a realistic way for ordinary people to generate energy for their homes and businesses. In the late 1950s and early 1960s, solar technology was implemented in space, installed on satellites both in U. The basics of solar energy are part of that discovery, as inventors and scientists lay the foundation for much of the later history of technology. .
