Polarizing organic photovoltaics (ZOPV) is a concept for harvesting energy from Liquid crystal display screens, [1] developed by engineers from UCLA.This concept enables devices to use external light and the LCD screen's backlight using photovoltaic polarizers.
Solar panels are also known as solar cell panels, solar electric panels, or PV modules. Solar panels are usually arranged in groups called arrays or systems . A photovoltaic system consists of one or more solar panels, an inverter that converts DC electricity to alternating current (AC) electricity, and sometimes other components such as ...
In a conventional solar cell light is absorbed by a semiconductor, producing an electron-hole (e-h) pair; the pair may be bound and is referred to as an exciton.This pair is separated by an internal electrochemical potential (present in p-n junctions or Schottky diodes) and the resulting flow of electrons and holes creates an electric current.
In 2004, physicist and science fiction author Gregory Benford calculated that a concave rotating Fresnel lens 1000 kilometres across, yet only a few millimeters thick, floating in space at the L 1 point, would reduce the solar energy reaching the Earth by approximately 0.5% to 1%. [26] The cost of such a lens has been disputed.
The Home Energy Saver website includes a section called LEARN which offers tips about energy savings, an explanation of the house-as-system energy efficiency approach, and other information to help people understand how energy is used in a home. When launched in 1994, Home Energy Saver was the first and only online home energy calculator.
The Climate Savers Computing Initiative was a nonprofit group of consumers, businesses and conservation organizations dedicated to promoting smart technologies that improve power efficiency and reduce energy consumption of computers. Formed in 2007, it was based in Portland, Oregon. [1]
