Brief Introduction

I moved to Zhonglab in January 2009 after completing my PhD at University of Surrey, UK.  My thesis was an investigation on highly efficient photovoltaic devices based on semi conductor nanocrystals, particularly infrared sensitive small bandgap materials.  Currently I am studying the exciton generation and charge transport in carbon nanotube based hybrid photovoltaics together with their device applications.

In 2006 I won the “Runners up” place in the Obducat Prize 2006 (Sweden) for the novel application of nanoimprinting lithography in organic photovoltaic devices (Appl. Phys. Lett., 90, 253502) (2007) (more info..)
