Our comprehensive suite of professional services caters to a diverse clientele, ranging from homeowners to commercial developers.

Light emission

  • In our group, we developed TADF, OLED and Perovskite light emitting devices.
  • We also developed active matrix display using TFT backplane.
  • We are also interested in surface chemistry of nanocrystal material to achieve promoted charge carrier mobility in the NC film as well as improved stability for luminescence.

Energy conversion

  • We are interested in understanding the fundamental material and devices physics, mainly the photon to charge carrier conversion,  to explore the theoretically attainable highest efficiency.
  • We are also interested in device design, material processing and material chemistry for the record power conversion efficiency of perovskite solar cells.
  • We are also in understanding the physical and chemical properties of perovskites to enhance the stability of perovskites devices.
