Materials for energy generation, storage and usage

The challenge of sustainable power is substantial, given an ever-increasing population that places demands on generation and usage of energy, in a context of global climate change and the critical need to curb carbon emissions. As part of a new era of sustainable energy there are critical needs for greater uptake of alternative sources, for better storage methods and for high efficiency usage. Our research addresses some of these areas and I will summarise the following three topics:

Carbon materials for energy storage and electrocatalysis – carbon materials and composites perform important functions in energy storage and usage. Research in the modification of carbon-based materials and how it changes the material properties in lithium sulfur batteries and electrocatalysis will be discussed.

Organic materials and devices for solar cells – organic photovoltaic (OPV) devices are based on the bulk heterojunction architecture. The phase separation and diffusion of materials is critical to their performance and we have used neutron reflectometry to understand the effect of annealing on the bulk heterojunction structure and performance.

Organic light emitting diodes based on small molecules – OLEDs are becoming ubiquitous in the market for portable electronic appliances largely due to their efficiency and easy processability. OLEDs are based on multilayers of organic materials on inorganic electrodes. The properties of the interfaces are critical to OLED performance and durability and our research has helped understand the effect of elevated temperature on the layers of such devices.
