Cell Structure

The cell membrane (AKA the plasma membrane) is a thin, flexible structure that surrounds the outside of the cell, creating a physical barrier between the cell interior and its external environment. It consists of a semipermeable lipid bilayer that regulates the passage of materials in and out of the cell.

Photovoltaic Cell – Definition and How It Works

A photovoltaic cell is an electronic component that converts solar energy into electrical energy. This conversion is called the photovoltaic effect, which was discovered in 1839 by French physicist Edmond Becquerel1. It was not until the 1960s that photovoltaic cells found their first practical application in satellite technology. Solar panels, which are made up of PV

How do solar cells work? Photovoltaic cells explained

PV cells, or solar cells, generate electricity by absorbing sunlight and using the light energy to create an electrical current. The process of how PV cells work can be broken down into three basic steps: first, a PV cell absorbs light and knocks electrons loose. Then, an electric current is created by the loose-flowing electrons.
