Photovoltaic Cell: Definition, Construction, Working
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 …
Working Mechanisms of Solar Cells
In this chapter, the working mechanism for traditional silicon-based solar cells is first summarized to elucidate the physical principle in photovoltaics. The main efforts are then made to discuss the different mechanisms for different types of solar cells, i.e. dye-sensitized solar cells, polymer solar cells, and perovskite solar cells.

How do solar panels work?
Researchers have produced ultrathin, flexible solar cells that are only 1.3 microns thick — about 1/100th the width of a human hair — and are 20 times lighter than a sheet of office paper.
Principles of solar cell operation
In solar cells with a simple geometry, light rays enter the cell through the front surface and, if not absorbed, leave through the rear surface of the cell. In these cells, even more sophisticated arrangements exist, which extend the path of light inside the cell and are usually referred to as optical confinement or light trapping.

Solar Cell Design Principles
For silicon solar cells, a more realistic efficiency under one sun operation is about 29% 2. The maximum efficiency measured for a silicon solar cell is currently 26.7% under AM1.5G. The difference between the high theoretical efficiencies and the efficiencies measured from terrestrial solar cells is due mainly to two factors.
