SOLAR CELLS Meaning and
Definition
-
Solar cells, also known as photovoltaic cells, are semiconductor devices that convert sunlight into electricity through the photovoltaic effect. These cells are specifically designed to harness sunlight and produce electric current when exposed to light.
Solar cells consist of several layers of different materials, typically made of silicon. The top layer is a thin, transparent material that allows sunlight to pass through and reach the underlying layers. This layer also acts as an anti-reflective coating to minimize light loss.
When sunlight strikes the solar cell, it excites the electrons in the semiconductor material, creating an electric current. This process occurs because the photons in sunlight have sufficient energy to displace electrons from their atomic orbits. The released electrons are then captured by the electrical circuit of the solar cell, producing direct current (DC) electricity.
Solar cells can be used individually or interconnected into photovoltaic modules, commonly known as solar panels. Multiple panels can be combined to build larger arrays for greater power output. These arrays are commonly used in solar energy systems for various applications, including residential, commercial, and industrial.
Solar cells provide a clean and renewable source of energy as they do not emit greenhouse gases or other pollutants during operation. With ongoing advancements, solar cells continue to improve in efficiency, durability, and cost-effectiveness, making them a crucial component in the transition to sustainable and eco-friendly energy sources.
Common Misspellings for SOLAR CELLS
Etymology of SOLAR CELLS
The word "solar" originates from the Latin word "sōlāris", which means "pertaining to the sun". It comes from the noun "sōl", meaning "sun".
The word "cells" in this context refers to the individual units that comprise the solar panel or the device that converts sunlight into electricity. The term "cell" is derived from the Latin word "cella", which means "small room" or "compartment". It was used to describe the smallest unit of a structure or organism. In the case of solar cells, it refers to the individual electrical units that generate electricity when exposed to sunlight.
