为了得到ZnSe∶O/ZnO核壳结构纳米线中间带太阳电池的最优吸收效率,通过时域有限差分法对纳米线的直径进行了优化,使纳米线的吸收光谱与太阳光谱相重合的波段有较高的吸收效率,并且使ZnSe∶O/ZnO纳米线的吸收光谱在带边和中间带有共振模式,从而使中间带太阳电池的吸收效率在ZnSe∶O的带边和中间带是最大的.为了进一步提高中间带的吸收效率,通过在纳米线两侧制备圆柱形铝天线的方法,利用金属铝天线的局域表面等离激元共振,使中间带太阳电池在中间带的吸收效率进一步增强到近两倍.这种方法为制备高性能的太阳电池和光探测器等光电器件开辟了新的途径.“,”For achieving an optimal absorption efficiency of ZnSe ∶ O/ZnO core/shell nanowire in termediate band solar cells,the diameter of the nanowire was optimized using the finite-difference time-domain method,the higher absorption efficiency was obtained in the wave band of the nanowire absorption spectrum coinciding with the solar spectrum,and the absorption spectra of ZnSe ∶ O/ZnO nanowires was in resonant mode at the band edge and intermediate band,then the absorption efficiency of the intermediate band solar cells was the largest at the band edge and the intermediate band of ZnSe ∶ O.In order to further improve the absorption efficiency of the intermediate band,the cylinder aluminum antennas were fabricated on both sides of the nanowire,by using the local surface plasmon resonance of the metal aluminum antennas,the absorption efficiency of the intermediate band solar cell was enhanced to about two times in the intermediate band.This approach opens a new way for the fabrication of high-performance optoelectronic devices such as solar cells and photodetectors.
