A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode. Solar cells are a form of photoelectric cell, defined as a device whose electrical characteristics –.

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 characteristics of Photovoltaic (PV) cells can be understood in the terms of following terminologies: Efficiency: Determines the ability to convert sunlight into electricity, typically measured as a percentage. Open-Circuit Voltage (Voc): Maximum voltage produced when not connected to any external load.
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.
Individual solar cells can be combined to form modules commonly known as solar panels. The common single junction silicon solar cell can produce a maximum open-circuit voltage of approximately 0.5 to 0.6 volts. By itself this isn’t much – but remember these solar cells are tiny.
The working of solar cell is based on photovoltaic effect. It is a effect in which current or voltage is generated when exposed to light. Through this effect solar cells convert sunlight into electrical energy. A depletion layer is formed at the junction of the N type and P type semiconductor material.
The main types of photovoltaic cells include: Silicon photovoltaic cell, also referred to as a solar cell, is a device that transforms sunlight into electrical energy. It is made of semiconductor materials, mostly silicon, which in turn releases electrons to create an electric current when photons from sunshine are absorbed.
