In plasmon-sensitized solar cells, layer self-assembly of gold nanoparticles surface plasmon reso- nance can produce photoelectric current. Photoelectric conversion efficiency of gold nanoparticles layer increa- ses with the intensity of surface plasmon resonance. The efficiency is up to O. 75%. We use the model to sim- ulate the phenomenon of charge separation, produce of photoelectric current and relationship between surface plasmon resonance and the photoelectric currents to explain the experimental results. In the future, these nan- oparticle materials have considerable potential applications in surface plasmon activated solar cells and solar cells plasmon.
