Research Interests

1. Energy Materials and Devices
I am interested to the energy conversion and energy storage. The energy conversion includes low-cost solar cells, such as polymer solar cells and dye-sensitized solar cells, and electrocatalysis. I am also interested to develop high-performance materials for energy storage. My lab achieved the highest photovoltaic efficiencies for dye-sensitized solar cells with carbon nanotubes and graphene as the counter electrode.

2. Nanometer Materials and Devices
My interests on nanometer materials include the development, processing and application of functional nanometer materials, such as carbon nanotubes, graphene, polymer/nanoparticle memory devices, and antibacterial nanocoating. Recently, we developed methods to directly deposit nanostructured metals on substrates through the chemical reduction of metal precursors.

3. Organic Electronic Materials and Devices
Organic electronic devices, including light-emitting diodes, photovoltaic cells, and field-effect transistors, have many important applications are regarded as the next-generation electronic devices due to their low fabrication cost and high mechanical flexibility. I am interested to the development of high-performance organic electronic materials and devices, including conducting polymers, conjugated polymers and organic molecules, photovoltaic cells and light-emitting diodes. We recently developed approaches to develop highly transparent and highly conductive polymer films. The polymer films have transparency and conductivity like indium tin oxide (ITO), the traditional transparent electrode material for optoelectronic devices.
