CFN Research Activities

We study application of Nanowires in photovoltaic and photo-electrochemical devices.  Using block-copolymer as template, we fabricate inorganic nanowires by glancing angle deposition and reactive ion etching.  Due to large surface-to-volume ratio, nanowires  can efficiently absorb light and charge separation distance can be very short allowing significant room to enhance the efficiency of solar cells .
