本文基于金属纳米粒子等离子体增强太阳电池,综合模拟分析了光吸收后的金属纳米粒子热效应和电池基体电效应,通过改变纳米粒子的尺寸、材料和形状,调控其光热过程和光电过程的能量转化.研究结果表明,Ag能更好的增强光电过程,Au能更好的增强光热过程;球形Ag粒子直径越大,光热过程和光电过程均增强;球形Au粒子直径越大,其光热过程增强而光电过程却减弱;圆柱形光电过程均减弱,且直径越大,光热过程增强.“,”Based on nanoparticle plasmonic solar cell,the photoelectronic performance of solar cell matrix and photothermal performance of nanoparticles after light absorption were comprehensively analysed.The energy conversion for photothermal or photoelectronic process can be regulated and controlled by varying particles' size materials and shape.The results show that silver particles give stronger enhancement on photoelectronic performance while gold particles behaves better on photothermal performance.For spherical silver particles,both the photoelectronic and photothermal performance could be enhanced with the increase of diameter.For spherical gold particles,photothermal performance would be enhanced but photoelectronic performance weakened.For both cylindrical silver and gold particles,photoelectronic performance could be weakened with the increase of diameter,while photothermal performance enhanced.
