Chemical company BASF is teaming up with the National University of Singapore's Graphene Research Centre (GRC) to improve the efficiency and flexibility of lighting devices by integrating graphene films into organic LEDs (OLEDs). GRC will handle graphene synthesis and characterisation, while BASF will contribute organic active materials for the development project.

"We are working towards a bright future where clean energy can be harvested, transported and stored in efficient ways, in order to be used to create a better and healthier living for all of us," said GRC Director Antonio Castro Neto.

The NUS team at GRC has already developed a patent-pending methodology for the reliable growth and transfer of high-quality graphene films onto different flexible substrates that can be used in solar cells and lighting panels. BASF develops and provides organic active materials that allow for its integration into a device, jointly with graphene films.

The goal of the collaboration is to develop a robust process of transferring and incorporating graphene in OLED devices. The researchers have to overcome the key challenge of working with atomically thin films of graphene and interfacing these films efficiently with organic materials. If successful, incorporating graphene into OLED and other devices based on electronically active organic materials will allow for inexpensive, flexible and more efficient gadgets.

"Graphene is a potentially important component in the future of lighting and low-weight energy storage. Through this cooperation, we aim to greatly advance the performance of graphene-based next generation organic electronic devices," said Dr Kitty Cha, a graphene research scientist at BASF and manager of the project.
