In this paper, the surface plasmon resonance of silver nanoparticles was analyzed and the relationship between the resonance peak and the environment, materials, size and other factors was analyzed. The principle of light-emitting diode and the physical mechanism of photoelectric conversion process were analyzed, and the way to improve the LED luminous efficiency was explored And the related theoretical basis; Analyze the nano-particles to enhance solar cell efficiency, analysis of spherical, square two kinds of silver nanoparticles of local surface plasmon extinction properties, and thus found that the shape and size of metal nanoparticles are The light absorption of the cell is affected, and the particle size of the nano particle is increased, which can increase the light absorption in the infrared band.
