Incorporation of plasmonic nanostructures
in these thin-film devices for light trapping offers an attractive solution to realize ultrahigh-efficiency OPVs with PCE>>10%. In this talk, I will review recent progress on plasmonic-enhanced OPV devices using metallic nanoparticles, and one-, two- and three-dimensional
(1-D, 2-D and 3-D) patterned periodic nanostructures.<sup>1,2</sup> A discussion will be given on the benefits of using various plasmonic nanostructures for broad band, polarization insensitive and angular independent absorption enhancement, and their integration
with one or two electrode(s) of an OPV device. <o:p></o:p></span></p><p class="MsoNormal" style="margin-left:.25in;text-indent:-.25in;mso-list:l0 level1 lfo1"><!--[if !supportLists]--><span style="font-size:9.0pt;mso-fareast-font-family:Cambria;mso-fareast-theme-font:

at the Naval Research Laboratory in Washington, DC where she established and led an interdisciplinary research team, and a section on Organic Optoelectronics. Her work has been motivated by newly emerging technologies based on organic electronics and photonics,
spanning a wide spectrum of disciplines photonics and electronics including the chemistry and physics of organic and nanostructured materials, organic nonlinear optics, light-emitting materials and devices, and photovoltaics. More recently, she joined the
National Science Foundation as the Director of the Division of Materials Research. She was the first woman to lead the largest and unarguably the most complex Division in the Mathematical and Physical Sciences Directorate. During her 3-year tenure, she managed
a budget portfolio close to one billion dollar, and oversaw the funding of single and group investigators, interdisciplinary research teams and centers, instrumentation and major facilities. In 2011, she took a</span><span style="font-size: 10pt; "> sabbatical
