OLED technology is widely used in televisions and is responsible for power efficient as well as bright displays. How about using the same technology while designing the roof of a car? Philips joined hands with BASF (a chemical company) to come up with a roof archetype for cars, which will comprise of transparent solar cells and OLED panels.
The OLEDs are transparent when switched off and provide light inside the vehicle when switched on. The roof is transparent and because of the presence of solar cells, will harness energy from the sun when it is bright outside. Apart from this, it will also let in natural light during daytime. The energy stored from sun rays will be used by transparent OLED panels to brighten up the inside of the car when dusk sets in. This means that sun rays will solve two purposes by providing energy to the panels that act as a car light and at the same time offer enough natural light during the day.
The solar panels will be directly smothered on the transparent OLED, which is a novel idea. The OLED in this case will be used to illuminate the car interiors and not act like a screen or display like it is used in many cars. The car roof is definitely unique and will act like a ceiling window. The concept is a breakthrough in OLED technology and gives an all new approach to automotive engineering. It will give the feel of open space and will also put up a clear outside view. So, use the solar-powered OLED sun roof as a source of light during night and like a window savor clear blue skies during the day.
