Today’s solar photovoltaic cells waste a large fraction of the energy that is abundant in sunlight. They absorb a range of wavelengths, typically from the blue to the near infrared. When one of these photons (a packet of sunlight) strikes the semiconductor inside a solar cell, a single electron is excited to a higher energy level.
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 photovoltaic effect is used by the photovoltaic cells (PV) to convert energy received from the solar radiation directly in to electrical energy .
Its primary function is to collect the generated electrons and provide an external path for the electrical current to flow out of the cell. The characteristics of Photovoltaic (PV) cells can be understood in the terms of following terminologies:
Due to the lowering of the purchase price, increasing the efficiency and lifetime of the photovoltaic systems, photovoltaics have become competitive in terms of comparing the LCOE with other energy sources in a substantial part of the world. All authors listed have significantly contributed to the development and the writing of this article.
A photovoltaic cell is a specific type of PN junction diode that is intended to convert light energy into electrical power. These cells usually operate in a reverse bias environment. Photovoltaic cells and solar cells have different features, yet they work on similar principles.

The photovoltaic effect
Voltage is generated in a solar cell by a process known as the "photovoltaic effect". The collection of light-generated carriers by the p-n junction causes a movement of electrons to the n-type side and holes to the p-type side of the junction. Under short circuit conditions, there is no build up of charge, as the carriers exit the device as light-generated current. However, if the light ...
