Best answer. The solar cells convert the sun’s energy into the electricity, They are building blocks of photovoltaic modules, They are known as the solar panels, Photovoltaic (PV) devices generate the electricity directly from sunlight via an electronic process that occurs naturally in certain types of material that called the semiconductors. These cells are made of different semiconductor materials and are often less than the thickness of four human hairs. A module’s ability to convert sunlight into electricity depends on the semiconductor. The main disadvantage of solar panels is, at night time it doesn’t work and the cost of installation is very high. They are also called solar cells. According to Energy.gov, the amount of energy that the sun provides is 10,000 times greater than the total energy use on Earth.

A photovoltaic panel is made up of an assembly of photovoltaic cells. A solar cell, or photovoltaic cell, is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. The overwhelming majority of solar cells are fabricated from silicon —with increasing efficiency and lowering cost as the materials range from amorphous (noncrystalline) to polycrystalline to crystalline (single crystal ) silicon forms. In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors. In 1954, scientists at Bell Telephone discovered that silicon, an element found in sand, created an electric charge when it was exposed to sunlight.
