 Energy is very important for sustainable development of the human environment. So really energy is a global issue and no single individual or no single country has got solutions to the energy problems. So what we're trying to do is trying to break the water molecule apart. Water is made from hydrogen and oxygen and we use this hydrogen as an energy source. We can burn this to get the energy that we want. In this case instead we'll be generating hydrogen using a clean energy, the sun, so it's quite sustainable and then also when hydrogen then combusts again with oxygen it will form water as its byproduct which is very environmentally friendly. Our research interests cover a broad spectrum from the very very fundamental issues of interest for example how can you really split water, what are the challenges and then what are the technologies which we need to develop in order to be able to split water. And of course those sorts of fundamental questions lead to new technologies which are of interest to the society and the broader community. You can imagine if we can are able to produce hydrogen sustainably and in large quantity then a lot of our energy needs and greenhouse problems will be solved. The hope is that by using this property of the semiconductor where it can absorb sunlight more efficiently and create this electricity so we can hopefully increase the efficiency of this water splitting.
