Solar Panels The discovery of solar energy can be traced back to the ancient times when people first noticed the warmth and light provided by the sun. However, the development of solar panels as a means of harnessing this energy began in the mid-19th century. In 1839, French scientist Edmond Becquerel discovered the photovoltaic effect, which is the process by which light is converted into electricity. He observed that when certain materials were exposed to light, they produced a small electric current. Although Becquerel's discovery was significant, it was not until the 20th century that solar panels began to be developed for practical use. In the 1950s, scientists at Bell Labs in the United States developed the first practical solar cell. These cells were made of silicon and were able to convert sunlight into electricity with an efficiency of around 6%. This was a significant improvement over previous attempts to create solar cells, which had much lower efficiencies. In the follo...
