The 21st century is witnessing a revolution in the area of electronics 
and photonics. Conventional semiconductor technology is being challenged 
by potentially inexpensive, flexible, and light-weight organic electronic,
optoelectronic and photonic devices. Recent progress in organic photovoltaics
(OPVs) revealed the realization of 10% power conversion efficiency (PCE)
putting them in direct competition with PVs based on amorphous silicon.
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 
patterned periodic nanostructures. 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.
