Frontier in Organic Solar Cells
Our group focus on the Design and Synthesis, Device Fabrication and Characterisation of Organic Semiconductors that can be applied in Organic Solar Cells, Organic Transistors and Detectors.
Our Interdisciplinary Research covers several disciplines including Chemistry, Material Science and Engineering, Physics, and Spectroscopy.
Our group achieved single-junction organic solar cells with a officially certified record efficiency of 11.5%,
This achievement is noted as a major technological breakthrough in the renowned NREL chart of “Best Research-Cell Efficiencies”.

We also discovered the Temperature-Dependent Aggregation behaviour of certain polymeric donor materials and utilise this phenomenon to fabricate high performance organic solar cells. The article reporting this phenomenon on Nature Communications has been cited over 1000 times. (Citations: 1317 till 9/2017)

We also discover a system of non-fullerene organic solar cell with a fast charge separation only requires a small driving force, that can achieve an open-circult voltage of 1.11V and a power conversion efficiency of 9.5%.
