Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.
The following are the most important performance parameters of a photovoltaic cell: The open-circuit voltage for a given material system and standard illumination conditions (see below) can be an indication of cell quality.
All the aspects presented in this chapter will be discussed in greater detail in the following chapters. The working principle of solar cells is based on the photovoltaic effect, i.e. the generation of a potential difference at the junction of two different materials in response to electromag-netic radiation.
Explore SuperCoaching Now The diagram above is a cross-section of a photovoltaic cell taken from a solar panel which is also a type of photovoltaic cell. The cell consists of each a P-type and an N-type material and a PN junction diode sandwiched in between. This layer is responsible for trapping solar energy which converts into electricity.
The basic processes behind the photovoltaic effect are: collection of the photo-generated charge carriers at the terminals of the junction. In general, a solar cell structure consists of an absorber layer, in which the photons of an incident radiation are efficiently absorbed resulting in a creation of electron-hole pairs.
The bottom layer, the last one may completely be covered by the material in which the conductor is made up of. A photovoltaic cell works on the same principle as that of the diode, which is to allow the flow of electric current to flow in a single direction and resist the reversal of the same current, i.e, causing only forward bias current.
Working Principles of a Solar Cell
Solar cells exploit the optoelectronic properties of semiconductors to produce the photovoltaic (PV) effect: the transformation of solar radiation energy (photons) into electrical energy. Note that the photovoltaic and photoelectric effects are related, but they are not the same. In both cases, light is absorbed, exciting an electron to a ...
