In plasmon-sensitized solar cells, layer self-assembly of gold nanoparticles surface plasmon resonance can produce photoelectric current. Photoelectric conversion efficiency of gold nanoparticles layer increases with the intensity of surface plasmon resonance. The efficiency is up to 0.75%. We use the model to simulate 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 nanoparticle materials have considerable potential applications in surface plasmon activated solar cells and solar cells plasmon.
