Energy has always played a vital role in human life. Any possible device made is driven by energy. From cycles, motorbikes to advanced metros, and aeroplanes everything requires some kind of energy conversion to carry out their work hence it becomes necessary to study energy conversion and efficiently manage energy resources.
The photovoltaic effect in a solar cell can be illustrated with an analogy to a child at a slide. Initially, both the electron and the child are in their respective "ground states." Next, the electron is lifted up to its excited state by consuming energy received from the incoming light, just as the child is lifted up to an "excited state" at the top of the slide by consuming chemical
A direct energy conversion device converts one form of energy to another through a single process. For example, a solar cell is a direct energy conversion device that converts optical electromagnetic radiation to electricity. While some of the sunlight that falls on a solar cell may heat it up instead, that effect is not fundamental to the
Photovoltaic Cell is an electronic device that captures solar energy and transforms it into electrical energy. It is made up of a semiconductor layer that has been carefully processed to transform sun energy into electrical energy. The term "photovoltaic" originates from the combination of two words: "photo," which comes from the Greek word "phos," meaning

Photovoltaic energy is the conversion of sunlight into electricity. A photovoltaic cell, commonly called a solar cell or PV, is the technology used to convert solar energy directly into electrical power. A photovoltaic cell is a nonmechanical device usually made from silicon alloys.
Photovoltaic cells (made of semiconductor material) absorb photons, elementary particles present in sunlight. The absorbed photons excite the electrons present in the photovoltaic cell and the movement of these electrons generates an electric current. In solar thermal conversion, solar energy is stored in the form of thermal energy.
