英文摘要： Metal nanostructures with quasi-periodic, aperiodic, random, and combination quasi-periodic with random will be developed by integrating mask technique, nanoimprint lithography, vacuum thermal evaporation and magnetron sputtering deposition technology, and combining with the finite difference time domain method (FDTD) simulations. The surface plasmon resonance effect of metal nanostructures can further be adjusted by dielectric materials, and its resonance wavelength can cover the entire visible region, and even near infrared area. Studying interaction mechanisms between metallic nanostructures and their surface plasmon effects, and excitons and carriers in the active layer. Metal nanostructures integrated with ultra-thin active layer (30-60nm) organic photovoltaic (OPV) cells would achieve the localized surface plasmon resonance (LSPR) in part coupled to short-range surface plasmon polaritons (SPP) modes, which will be helpful to increase ultra-thin active layer "optical thickness" closing to the "optical thickness" of traditional active layer of 80-250nm and control Ohmic damping loss in metallic nanostructures.Overcoming the increase of interface barrier and carrier recombination, and the decline of the parallel resistance Rp caused by ultra-thin active layer OPV cells by interface modification methods and ce
