BASF and Philips have partnered to develop and manufacture a vehicle roof based on organic light-emitting diode technology. When turned off, the OLED roof allows sunlight to penetrate the car while collecting energy using transparent solar cells. "This ... allows the driver to enjoy 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 of BASF Future Business.
