The demand for exploring an efficient way to address fossil fuel exhaustion and global warming concern is becoming more and more intensive. Converting solar energy to electricity or clean fuel have been proved a promising way by many scientific researchers. However, very limited conversion efficiency and the high cost of present devices extremely blocked its large-scale application. Semiconductor nanocrystal quantum dots (QDs) recently have drawn much attention due to their high absorption coefficient, size-tunable optical properties and low fabrication cost. But how to achieve high power conversion efficiency of QDs based devices is still a challenge.
My main research interests are (i) exploring new green quantum dots with tunable morphology and size; (ii) engineering novel methods to modified surface properties of quantum dots; (iii) the application of the surface modified quantum dots in quantum dots sensitized solar cells (QDSSC) or hydrogen generation.
