Large and periodic anti-ring arrays are fabricated by using a monolayer of polymer/nanosphere hybrid technique and applied as back reflectors in substrate-type hydrogenated amorphous silicon (a-Si:H) thin-film solar cells. The structure of each anti-ring comprises a nanodome centered inside a nanohole. The excitation of Bloch wave surface plasmon polaritons is observed in the Ag-coated anti-ring arrays. The nanodomes of the anti-ring arrays turn out to enhance large-angle light scattering and increase the effective optical path in the solar cell. The resulting efficiency of an ultrathin a-Si:H (thickness: 150 nm) solar cell is enhanced by 39% compared to that with a flat back reflector and by 13% compared to that with a nanohole back reflector.
通过使用聚合物/纳米球单层混合技术制备了大型周期性抗反射环阵列，并将其用作衬底型氢化非晶硅（a-Si:H）薄膜太阳能电池的背反射器。每个抗反射环的结构包括一个位于纳米孔中心的纳米穹顶。在涂有银的抗反射环阵列中观察到了布洛赫波表面等离子体激元的激发。结果表明，抗反射环阵列的纳米穹顶增强了大角度光散射，并增加了太阳能电池中的有效光程。与使用平面背反射器的超薄a-Si:H（厚度：150nm）太阳能电池相比，其效率提高了39%，与使用纳米孔背反射器的太阳能电池相比提高了13%。
