| 摘 要： | 太阳能电池的吸收效率低是制约太阳能电池性能的主要因素之一。为了解决这一问题提出了一种新的结构模型。该模型可以激发局域表面等离子体共振、表面等离子体共振、光子模式、磁极子激元这4个效应。通过时域有限差分法对该模型的效果进行了模拟,并对其结构进行优化,从而使各个效应能够互相耦合,使吸收层吸收率达到一个优值。结果表明,最终优化完成的结构的总体提升系数较常规太阳能电池提高了2.39倍。

| Abstract: | The low absorption efficiency of solar cells is one of the main factors that restrict the performance of solar cells.In order to solve this problem,a new structure model is proposed which can stimulate the four effects:localized surface plasmon resonance,surface plasmon resonance,photon mode and magnetic polaritons.The effect of the model is simulated by finite difference time domain.Meanwhile,the structure size is optimized so that all the effects can be coupled to each other,leading to a good value of the absorptivity of absorption layer.The overall lifting coefficient of the final optimized structure is 2.39 times higher than that of the conventional solar cell. |
