It is accepted by most that the world must transition to an economy in which carbon emissions are drastically reduced. One of the things that has to be in place in order to arrive at that state is that new technologies must be invented. And that is where world-leading unviersities, such as UQ, come in. We have some of the world’s most highly cited researchers and one of those, Lianzhou Wang, is a superstar in nanotechnology. My research focuses on the development of functional materials for the clean energy conversion and storage. like solar energy conversion and also the new type of battery. And his latest invention, along with his colleagues, is to improve the efficiency of energy capture by quantum dot solar cells. From about 13.5% to about 16.5% of the energy that is shone on it. So that’s virtually a 25% efficiency gain in one step. With much more to come. Quantum dots is a very tiny nanoparticles which have a very small size but can have a very unique property different from a large particle. Quantum dots can have very diverse applications in a number of important areas such as electronics, photovoltaic, LED, and sensing applications. Quantum dots based solar cells has the advantage of printing on flexible electronics and also can be used for indoor lighting and indoor electricity generation. Which means you can use very big lights to generate electricty efficiently. This means if you use lighting like this they’re very weak and we can generate electricty for the indoor application. We’re very excited about our recent breakthrough in quantum dots solar cells which achieved the record high efficiency but more importantly it can be used broadly beyond the solar cell application. Our quantum dots cells are actually semi transparent that means, by integrating the quantum dot solar cell as the photovoltaic window it can produce electricty for sure but in the meantime it can still allow some part of the light coming through it will look like a tinted window. We can simply use the quantum dot ink we’re developing to coat a very thin layer on top of glass. That is the way we produce photovoltaic window. We are now developing the technology to roll-to-roll print the solar cell and which actually can be like a printed layer by layer like a newspaper The quantum dots we’ve developed not only can be used in high efficiency solar cells for the electricity generation but can also be used for hydrogen production by splitting water which I think is also equally important. Very exciting. So the hydrogen can be used as a clean fuel to power our economy. It’s research like that that gives me hope that the world will be able to have enough energy to increase prosperity globally but at the same time, to reduce carbon emissions drastically. I really enjoy the research in finding some unique and a new property in the material we developed and which can be used so our society and committee for a better future.
