How to save energy with Solar OLED?

According to a researcher at the London Centre for Nanotechnology, they could soon include photovoltaic cells behind a screen smartphone. Ahnood Arman says that only 36% of the light produced by an OLED screen is projected out and the rest is wasted. This is what led him to have the idea of creating a line of photovoltaic cells on the back and the OLED screen, to capture this wasted light and produce energy that can be used to charge the battery.

These cells have the form of a thin film, and the idea is to collect this photovoltaic layer to the layers that make up the OLED display. Since this type of screen is not fully opaque, the film photovoltaics is also able to collect the ambient light produced by the addition of the screen to produce energy.

Today this system has an average efficiency of 11%, considerably less than the commercial photovoltaic cells that reach the 30%, and produces a total of five milliwatts.

The next step is to experiment with other designs and materials to increase this efficiency.
