Nanomaterials have opened up new avenues for generating clean energy in an efficient and cost-effective way. Our research is primarily focused on developing novel nanomaterials to tackle the challenges of the next-generation photovoltaics, which include perovskite and organic solar cells. Our group members come from a widely diverse scientific background, ranging from organic synthesis, material processing and device engineering. We work together to bring innovative ideas into reality.
Perovskite solar cell
One of the main challenges of perovskite solar cell is mass production at low cost and low temperature. We develop high efficiency perovskite solar cell at low temperature and on flexible substrate. We apply solution-processed nanomaterials to demonstrate printed perovskite solar cell for commercialization. We also strive to improve our understanding of the key fundamental processes in a working device.
Perovskite light-emitting diode
We are also actively working on exploring the potential of perovskite in other optoelectronics such as light-emitting diode (LED). Through molecular engineering, we developed new perovskite emitters that are not only highly luminescent but also possess tunable emission color. We have demonstrated multi-colored perovskite LEDs that can potentially be used in display and lighting industry in the near future.
Organic solar cell
Organic solar cells have the advantage of high degree of freedom in the materials design and selection. For a more efficient energy conversion, it is necessary to understand the solid-state structure from the nano- to macro-scale encompassing the entire device. Our group has developed novel π -conjugated molecules, focusing on the effect of additives and other processing conditions in their crystallinity and nanomorphology. we are also working on the development of printed flexible organic solar cell.
