It is the heart of the solar power plant.

Solar panel working principle ppt.

Engineers and scientists who desire anintroduction to the field. The absorption of light generating either electron hole pairs or excitons. Solar panel technology ppt 1. Silicon solar cell principle p n junction diode.

Solar panels consists a number of solar cells. A presentation on solar energy solar panels 1 25 2013 submitted by. Introduction history working principle types of solar cells benefits application disadvantages final thought bibliography further reading 2 3. It is written to address several audiences.

In the solar photovoltaic system solar energy is directly converted to electric power. Light photon energy electric energy silicon solar photovoltaic cells a device made of semiconductor materials that produce electricity under light a p n junction is created in silicon by a doping process. The energy obtained from the sun directly into the electrical energy. The energy produced by each solar cell is very small but combining the energy of 35 of them we have got enough energy to charge a 12 volt battery.

The solar cell technology is the fastest growing power generating technology. The majority of solar cells are fabricated from silicon with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms. Principles and me1hods seri sp 290 1448 solar information module 6213 published february 1982 this book presents a nonmathematical explanation of the theory and design of pv solar cells and systems. Working principle of silicon solar pv cells photovoltaic material of device converts.

This makes the system far more convenient and compact compared to thermal methods of solar energy conversion. We have got around 35 solar cells in one panel. Sio 2 p si node n si node sio 2 sio 2 sio 2. Solar cell any device that directly converts the energy of light into electrical energy through the photovoltaic effect.

A solar cell is a solid state electrical device that converts energy of light directly into electricity by photoelectric effect. The operation of a photovoltaic pv cell requires 3 basic attributes. The basic principle behind the function of solar cell is based on photovoltaic effect. Maximum power point tracking mppt or sometimes just power point tracking ppt is a technique used commonly with wind turbines and photovoltaic pv solar systems to maximize power extraction under all conditions.

Bypass diodes working when. Solar cell is a device or a structure that converts the solar energy i e. Although it primarily applies to solar power the principle applies generally to sources with variable power. For example optical power transmission and thermophotovoltaics.

Hi friends in this article i am going to discuss about solar panel working principle and hope you will like my effort. When light reaches the p n junction the light photons can easily enter in the junction through very thin p type layer the light energy in the form of photons supplies sufficient energy to the junction to create a number of electron hole pairs.
