Chemical manufacturer BASF & Technology innovators Philips have come up with a concept design, where they have developed a form of OLED technology for car roofs that can function as both lighting and as a sunroof, capable of integrating solar cells to generate power. This means all required energy including additional electricity for the vehicle can be obtained by including transparent solar cells into the modules. The combination of OLED lights and solar cells gives the driver a unique open-space feeling, while it generates electricity during the day and pleasantly suffuses the interior with the warm light of the transparent, highly efficient OLEDs at night," said Felix Gorth, head of organic light-emitting diodes and organic photovoltaics at BASF Future Business GmbH.
When switched off, the OLEDs are transparent, so the roof behaves like transparent glass, allowing rays of sunshine to fill your car and during rain, you can enjoy the rain falling on the transparent OLED as you drive. All the while, the solar cells would collect energy and at night, when activated, the roof turns opaque and the stored energy can be used to provide light to the interior of your vehicle.
