我们证明硅纳米孔阵列作为一个上级太阳光吸收纳米结构的光伏太阳能电池的应用。在1 sun AM 1.5G光照下,通过P扩散形成p-n结的Si纳米孔太阳能电池的开路电压为566.6mV,短路电流密度为32.2mA/cm(2),功率转换效率为9.51%,显著高于基于Si纳米线、平面Si和织构Si的太阳能电池。纳米孔阵列的几何形状提出了一种新的和可行的方法,成本效益的太阳能转换。
We demonstrate Si nanohole arrays as a superior sunlight-absorbing nanostructure for photovoltaic solar cell applications. Under 1 sun AM1.5G illumination, a Si nanohole solar cell with p-n junctions via P diffusion exhibited a open-circuit voltage of 566.6 mV, a short-circuit current density of 32.2 mA/cm(2), and a remarkable power conversion efficiency of 9.51%, which is higher than that of its counterparts based on Si nanowires, planar Si, and pyramid-textured Si. The nanohole array geometry presents a novel and viable method fo cost-efficient solar energy conversion.
