摘要

在本文中，我们模拟了一种纳米圆盘反射器阵列，它可以增强光捕获，以克服薄晶硅(c-Si)低吸收的局限性。我们对厚度小于20$\mu$m的薄c-Si吸收层电池设计进行了数值模拟。我们的研究结果表明，与平面金属反射器相比，可以实现高达22.9%的潜在短路电流增加，有效地增加了一倍的光程长度。

Simulation of Light Trapping in Ultra-thin Crystalline Silicon Absorber with Silver Nanodisc Back Reflector

In this paper we simulate a nanodisc reflector array that can enhance light trapping to overcome the limitations of low absorption in thin crystalline Si (c-Si). We performed a numerical simulation for a cell design with a thin c-Si absorber layer less than 20$\mu$m thick. Our results show that a potential short circuit current increase of up to 22.9% is achievable, effectively doubling the optical path length compared to a planar metallic reflector.
