Polarizing organic photovoltaics (ZOPV) is a concept for harvesting energy from screens, developed by engineers from. This concept enables devices to use external light and the screen's backlight using photovoltaic polarizers. Photovoltaic polarizers convert this light into electricity which can be used to power the device. This concept also provides multifunctional capability to devices with LCD screens as they act as photovoltaic devices and as.
