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.
The ability to model PV device outputs is key to the analysis of PV system performance. A PV cell is traditionally represented by an equivalent circuit composed of a current source, one or two anti-parallel diodes (D), with or without an internal series resistance (R s) and a shunt/parallel resistance (R p).The equivalent PV cell electrical circuits based on the ideal …

Photovoltaic cells degradation is the progressive deterioration of its physical characteristics, which is reflected in an output power decrease over the years. Consequently, the photovoltaic module continues to convert solar energy into electrical energy although with reduced efficiency ceasing to operate in its optimum conditions.
Understanding the equivalent circuit of a solar cell is more than just a theoretical exercise; it is a bridge between conceptual understanding and practical application. The equivalent circuit of a solar cell can help us visualize and explain the behaviour of solar cells, providing vital information to help us make them more efficient.

The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device. The theoretical studies are of practical use because they predict the fundamental limits of a solar cell, and give guidance on the phenomena that contribute to losses and solar cell efficiency.
Electron Hole Formation. As we know that photon is a flux of light particles and photovoltaic energy conversion relies on the number of photons striking the earth. On a clear day, about 4.4 x 10 17 photons strike a square centimeter of the Earth''s surface every second. Only some of these photons that are having energy in excess of the band gap are convertible …
