A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron vacancy or “hole” is created.
A photovoltaic cell harnesses solar energy; converts it to electrical energy by the principle of photovoltaic effect. It consists of a specially treated semiconductor layer for
Photovoltaic Cell: Photovoltaic cells consist of two or more layers of semiconductors with one layer containing positive charge and the other negative charge lined adjacent to each other.; Sunlight, consisting of small packets of energy termed as photons, strikes the cell, where it is either reflected, transmitted or absorbed.
Two main types of solar cells are used today: monocrystalline and polycrystalline.While there are other ways to make PV cells (for example, thin-film cells, organic cells, or perovskites), monocrystalline and polycrystalline solar cells (which are made from the element silicon) are by far the most common residential and commercial options. Silicon solar

A silicon photovoltaic (PV) cell converts the energy of sunlight directly into electricity—a process called the photovoltaic effect—by using a thin layer or wafer of silicon that has been doped to create a PN junction.
Solar Cell Design Principles. Solar cell design involves specifying the parameters of a solar cell structure in order to maximize efficiency, given a certain set of constraints.

5. Construction of Solar Cell Solar cell (crystalline Silicon) consists of a n-type semiconductor (emitter) layer and p-type semiconductor layer (base). The two layers are sandwiched and hence there is formation of p-n junction. The surface is coated with anti-refection coating to avoid the loss of incident light energy due to reflection. A proper metal contacts are
The p-side is relatively thick and is at the back of the solar cell. Both the p-side and the n-side are coated with a conducting material. The n-side is coated with an anti-reflection coating which allows visible light to pass through it. The main function of this coating is to reflect the IR (heat) radiations and protect the solar cell from heat.
