A photovoltaic (PV) cell is an energy harvesting technology, that converts solar energy into useful electricity through a process called the photovoltaic effect.There are several different types of PV cells which all use semiconductors to interact with incoming photons from the Sun in order to generate an electric current.

WhatsAppThe working principle of solar cells is based on the photovoltaic effect, i.e. the generation of a potential difference at the junction of two different materials in response to electromag-netic radiation. The photovoltaic effect is closely related to the photoelectric effect
WhatsAppThe first demonstration of the photovoltaic effect, by Edmond Becquerel in 1839, used an electrochemical cell. He explained his discovery in Comptes rendus de l''Académie des sciences, "the production of an electric current when two plates of platinum or gold immersed in an acid, neutral, or alkaline solution are exposed in an uneven way to solar radiation."

WhatsAppSolar energy can be used directly to produce electrical energy using solar PV panels. Or there is another way to produce electrical energy that is concentrated solar energy. In this type of plant, the radiation energy of solar first converted into heat (thermal energy) and this heat is used to drive a conventional generator.
WhatsAppTwo 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 …
WhatsAppPhotovoltaic (PV) cells, or solar cells, are semiconductor devices that convert solar energy directly into DC electric energy. In the 1950s, PV cells were initially used for space applications to power satellites, but in the 1970s, they began also to be used for terrestrial

WhatsAppphotovoltaic electricity is produced directly from sun light by converting the energy in sunlight into free charged particles within certain kinds of materials.
WhatsAppPhotovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.
WhatsAppSolar Power: Solar power is an indefinitely renewable source of energy as the sun has been radiating an estimated 5000 trillion kWh of energy for billions of years and will continue to do so for the next 4 billion years. Solar energy is a form of energy which is used in power cookers, water heaters etc. ...
