Solar Cell Construction Materials

Photovoltaic cells are made of special materials called semiconductors such as silicon.

Solar cell construction materials.

Special materials are used for the construction of photovoltaic cells. Solar panels are very benign and even when damaged the cells do not cause any contamination as the cells are encapsulated and contain no readily soluble materials. Construction of solar cell. A solar cell is basically a junction diode although its construction it is little bit different from conventional p n junction diodes a very thin layer of p type semiconductor is grown on a relatively thicker n type semiconductor we then apply a few finer electrodes on the top of the p type semiconductor layer.

Thereby the solar panels are made by using the series parallel combination of the cells. It also gives a wide option of materials that can be used in the construction including flexible and light weight materials. However like all appliances solar panels need to be collected and recycled at the end of life which we discuss in the section below. The most commonly used semiconductor material for the construction of photovoltaic.

And the combination of the solar modules together is known as the solar panel. It is a form of photoelectric cell defined as a device whose electrical characteristics such as current voltage or resistance vary when exposed to light. Most current research aims for reducing solar cell cost or increasing efficiency. The solar module is constructed by connecting the single solar cells.

Likewise egypt botswana and the philippines all three assisted by american companies are building plants that will manufacture solar cells. The light incident on the semiconductor material may be pass or reflected through it. These electrodes do not obstruct light to reach the thin p type layer. A solar cell or photovoltaic cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect which is a physical and chemical phenomenon.

An atom of silicon has 14 electrons arranged in three different shells. Solar energy materials solar cells is intended as a vehicle for the dissemination of research results on materials science and technology related to photovoltaic photothermal and photoelectrochemical solar energy conversion materials science is taken in the broadest possible sense and encompasses physics chemistry optics materials fabrication and analysis for all types of materials. Individual solar cell devices are often the. Solar cell is a device or a structure that converts the solar energy i e.

Working of pv cell. These materials are called semiconductors.
