Solar panels a non-convention energy source

All of us are aware of a term known as ‘Energy’. It is required in every field of modernization. And it is being generated by two types of sources. The first one is known as conventional energy sources and the second one is known as non-conventional energy sources.

Conventional energy sources such as natural gas, oil, coal, or nuclear fuels like uranium and plutonium are finite but still hold the majority of the energy market. But continuous and consistent extraction of these sources is generating two major problems. The first problem is that we are exhausting these energy sources at a high pace. And the second major problem is that conventional energy sources emitted many environmental pollutants like radioactive isotopes, co2, several hydrocarbons, and much more. To solve these problems human civilization is now moving towards clean and green energy sources also known as ‘Non-conventional energy sources’.

Types of non-conventional energy sources are such as wind, solar, tidal, and others. The main significance of non-conventional energy sources are clean and echo friendly. These energy sources generate very little or no environmental waste. Here we are going to discuss solar panels that generate Solar power.

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.

Working of Solar Panels:

The solar panel is a set of solar-cells. These several solar-cells or photovoltaic cells generate electricity by using sunlight. When sunlight hits the semiconductors like silicon and selenium
