Solar Cells in Smartphone Screens

FROM IEEE Spectrum

Researchers at the London Centre for Nanotechnology at University College London have their sights set on a goal that will make the legions of cellphone users happy: handsets that go a week or more without charging. Eventually, they believe, we might see a phone that never needs to be plugged in. To extend the time between charges, the London group built a prototype device that converts ambient light into electricity using an array of solar cells—made of thin-film hydrogenated amorphous silicon—that’s designed to sit beneath the phone’s screen. The photovoltaic cell takes advantage of the smartphone display’s large footprint. The energy harnessing system also captures much of the light from a typical organic light-emitting diode display that, instead of being projected out of the front of the screen, escapes at the edges, where it is useless.

That will be more complicated that the phone screen will be solar cells at same time as touch screen.

One Response to Solar Cells in Smartphone Screens

  1. Fiona Ruberto says:

    Solar cells are the basic component of any active system used to convert sunlight into a form of energy. Traditionally, solar cells were used as the key part of panel systems that generated electricity or heat for homes. These days, the technology is used in a wide variety of applications, which means the style of solar cells vary per application.`
