Get a deep insight into Photovoltaic cells in this article, by learning its basics such as definition, characteristics, construction, working, and applications. What is a Photovoltaic Cell? A photovoltaic cell is a specific type of PN junction diode that is intended to convert light energy into electrical power.
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
