英文摘要： The major goal of this project is to develop new types of palsmon-enhanced solar cells with lower cost and higher efficiency. Surface plasmon resonance (SPR), f？rster resonance energy transfer (FRET) and internal electron emission (IEE) have been used for guiding light, energy and charge carriers at the nanoscale. By using new materials (graphene, quantum dots, plasmonic nanoparticles, semiconducting nanowires, etc) and new technologies (electron beam lithography, etc), these physical effects could provide new opportunities to design novel solar cells. On the basis of the previous works in nanomaterials synthesis and device fabrications in our lab, in this project we will exploit the use of plasmonic enhancement in combination with FRET and IEE to construct new types of solar cells. Gaphene/silicon nanowires-based field effect transistors (FETs) will be made to investigate the plasmonic enhancement effect and charge injection or energy transfer at the interface. After understanding the interfacial mechanisms, we will construct new types of plasmon-enhanced solar cells, for example, plasmon-enhanced internal electron emission-based graphene solar cells, plasmon-enhanced internal electron emission/Schottky tandem solar cells and plasmon-enhanced hybrid resonance organic-inorganic solar cells.
