1.  Interface engineering on organic solar cells and perovskite solar cells

The interface layer plays significant role on improving the efficiency and stability of organic solar cells and perovskite solar cells. This project is aimed at developing new ideal interfacial materials with low price, friendly environment, good electrical conductivity, and suitable for roll-to-roll fabrication of high-performance devices. The work mechanism of interfacial layer, especially the exciton separation and carrier transport at the interfaces are then studied.

2.  Photoelectrocatalysis and photovoltaic electrocatalysis

Artificial photosynthesis uses solar energy to convert CO2 and H2O into chemicals, which is the main research focus of our group. In this direction, photoelectrocatalysis (PEC) and photovoltaic electrocatalysis (PV-EC) are used to reduce water/CO2 to H2 or chemicals/ fuels.

      3.  Integrated photovoltaic - energy storage devices

Due to the fluctuation and intermittency of sunlight, the power output of photovoltaic cells is unstable. The integrated photovoltaic-energy storage devices convert and store solar energy in one device simultaneously, could apply to different power levels, providing solutions for distributed photovoltaic network, smart micro grid, portable devices, Internet of things and other applications.
