TN1; Surface plasmon resonance of noble metal nanoparticles leads to the optical absorption enhancement effects,which have great potential applications in solar cell.By using the general numerical method of discrete dipole approximation(DDA),we study the absorption and scattering properties of two-dimensional square silver nanodisks(2D SSN)arrays on the single crystal silicon solar ceil.Based on the effective reflective index model of the single crystal silicon solar ceil,we investigate the optical enhancement absorption of light energy by varying the light incident direction,particle size,aspect ratio,and interparticle spacing of the silver nanodisks.The peak values and position of the optical extinction spectra of the 2D square arrays of noble metal nanodisks are obtained with the different array structures.
