What are Solar panels?
A solar panel is a gadget that converts light into electricity. Several solar-cells are connected to generate electric power.
When we are considering solar power we found that it is nothing new. In history, people have used solar power as far back in the 7th century B.C. The uses of solar power included focusing the sun’s energy through a magnifying glass to start fires for cooking or generating heat. Sun-rooms were invented in ancient times to capture heat for its natural warmth.
In 1839, a French physicist was working with a cell made of metal electrodes in conducting solution. During this time he found that the cell produces more electricity when it was exposed to sunlight. Later in 1873, Willoughby Smith discovered that selenium could function as a photoconductor. After three years later, in 1876 William Grylls Adams and Richard Evans Day applied the photovoltaic principle discovered by Becquerel to selenium. They had noted that it could, in fact, generate electricity when exposed to light.
In 1905, When Albert Einstein published a paper on the photoelectric effect. This generated more attention towards solar energy. A big breakthrough came in 1954 when three scientists, Daryl, Calvin, and Gerald of Bell Labs created a more practicable solar cell using silicon. This invention formed a foundation for modern solar cells. So we can say that solar cell modernization is a gradual process. It is not a one-day job.
