We investigate silicon nanohole arrays as light absorbing structures for solar photovoltaics via simulation. To obtain the same ultimate efficiency as a standard 300 microm crystalline silicon wafer, we find that nanohole arrays require twelve times less silicon by mass. Moreover, our calculations show that nanohole arrays have an efficiency superior to nanorod arrays for practical thicknesses. With well-established fabrication techniques, nanohole arrays have great potential for efficient solar photovoltaics.
我们通过模拟研究了硅纳米孔阵列作为太阳能光伏的吸光结构。为了达到与标准 300 微米晶体硅片相同的最终效率，我们发现纳米孔阵列所需的硅材料质量减少了 12 倍。此外，我们的计算表明，对于实际厚度，纳米孔阵列的效率优于纳米棒阵列。凭借成熟的制造技术，纳米孔阵列在高效太阳能光伏方面具有巨大的潜力。
