研究方向 / Research




In general, the goal of our research is to put the materials working for solar energy conversion. Currently we focus on the following projects.

  1. Sb2(S,Se)3 Solar Cell
Antimony sulfide-selenide (Sb2(S,Se)3) is a kind of semiconducting material with earth abundant element storage, good long-term stability, and tunable band gap in 1.1-1.8 eV. In principle, it is an excellent light absorption material and can deliver maximum efficiency of >30% according to the Shockley-Queisser limit. The major challenge in this kind of device is to boost the efficiency to a level comparable to the established solar technologies such as thin film solar cells and perovskite solar cells. In this research, we focus on the development of synthetic methodologies toward Sb2(S,Se)3, device fabrication and efficiency improvement.

  2. Ag(Sb,Bi)(S,Se)2 Solar Cells
Ag(Sb,Bi)(S,Se)2 possesses tuanble bandgap, abundant element storage and excellent stability, which is promising for solar cell applications. This project focuses on the film fabrication, investigation on the basic properties such as the point defect and carrier dynamics. The final goal is to design suitable device structures for high efficiency solar energy conversion.
  3. Energy Storage Materials and Devices  
With the rapid development of electric vehicle industry, higher requirements are put forward for the energy density and power density of lithium-ion batteries (LIBs). The key of high performance LIBs relies on the electrode materials. Therefore, the development of new electrode materials with higher specific capacity and better cycle life has always been the key to the development of LIBs. We commit to the research and development of high-performance electrode (cathode and anode) materials for LIBs.

The limited lithium resource and poor safety constrain the application of LIBs in large-scale energy storage. Therefore, it is of great significance to develop alternative rechargeable batteries with low cost, acceptable safety, and long cycle life. Aqueous zinc-ion batteries (ZIBs) are considered promising energy storage devices for large-scale energy storage systems as a consequence of their safety benefits and low cost. In this project, we focus on the energy storage mechanisms of new cathode materials with high specific capacity and long cycle life for ZIBs.
  4. Hydrogen Generation  
Hydrogen(H2) is not only a clean and efficient energy source, but also a vital chemical material. It is mainly derived from electrolysis of water and coal reforming, but these methods are not environment protecting methods. Here we target to developing integrated system can converts solar energy into hydrogen efficiently. The main task is to developing a solar hydrogen evolution system which combines efficient hydrogen evolution catalysts with lower cost solar cells.
