What is photovoltaic system?

The photovoltaic power system (PV) is referred to as systems that generate electrical energy using sunlight. These systems have different components that are responsible for absorbing light and converting it into electrical energy by a part called a solar panel or solar panel. The quality and kind of knowledge of making this piece has a great impact on increasing production.

Contrary to popular belief, these systems are by no means considered modern systems, and their discovery was first made in the eighteenth century by the French scientist Alexandre Edmond Becquerel about 200 years ago. By claiming that “an electrode coupled to a conductive metal after absorbing sunlight has the capability of generating electrical energy,” in 1839, he was able to produce a trivial and very simple product with a very low yield and limited in size for some laboratory purposes. Sunlight was invented.

The first solar cell was built in the 1880s by a German engineer Charles Frittz, made of copper oxide. In 1931, another German scientist, Bruno Lange, was able to replace the silver selenide composition with copper oxide, which could only convert 1 percent of solar energy to electrical energy. After this relatively revolutionary discovery, other scholars such as Russell Ohl, Gerald Pearson, Calvin Fuller and Daryl Chapin completed it and built the first silicon solar cell in 1954. It was the first generation of silicon cells, and to this day it is considered as the cornerstone of most solar panels. They cost about $ 286 per watt (in 1954) with efficiency and efficiency of about 5 percent for today’s panels at around $ 0.29 per watt, with a productivity of at least 17 percent.
