Solar cell - Simple English Wikipedia, the free encyclopedia

Solar cells have many applications. They have long been used in situations where electrical power from the grid is unavailable, such as in remote area power systems, Earth-orbiting satellites and space probes, consumer systems, e.g. handheld calculators or wrist watches, remote radiotelephones and water pumping applications. More recently, they are starting to be used in assemblies of solar ...

Photovoltaics - Simple English Wikipedia, the free ...

A solar cell or photovoltaic cell is a device that changes light energy into electricity. Photovoltaics are best known as a method for making electricity by using solar cells to change energy from the sun into a flow of electrons. The photovoltaic effect was first noticed by Alexandre-Edmond Becquerel in 1839.

Third-generation photovoltaic cell - Wikipedia

Solar cells can be thought of as visible light counterparts to radio receivers. A receiver consists of three basic parts; an antenna that converts the radio waves (light) into wave-like motions of electrons in the antenna material, an electronic valve that traps the electrons as they pop off the end of the antenna, and a tuner that amplifies electrons of a selected frequency. It is possible to build a solar cell identical to a radio, a system known as an optical rectenna, but to date these have not been practical.

Solar panel - Simple English Wikipedia, the free encyclopedia

Over 90% of the solar panel is recyclable to create either new solar panels or scrap material. First, the panels are broken down by removing the metal frames and glass plate, leaving the group of solar cell sandwiched between an ethylene vinyl acetate (EVA) resin and back film.

Solar panel - Wikipedia

A solar panel, or photo-voltaic (PV) module, is an assembly of photo-voltaic cells mounted in a framework for installation.Solar panels use sunlight as a source of energy and generate direct current electricity.A collection of PV modules is called a PV Panel, and a system of Panels is an Array. Arrays of a photovoltaic system supply solar electricity to electrical equipment.

Solar cell efficiency - Energy Education

Efficiency is the comparison of energy output to energy input of a given system. For solar photovoltaic (PV) cells, this means the ratio of useful electrical energy they produce to the amount of solar energy incident on the cell under standardized testing conditions. Although some experimental solar cells have achieved efficiencies of close to 50%, most commercial cells are below 30%.
