Multiscaled hierarchical nanostructures for enhancing the conversion efficiencyof crystalline silicon solar cells
提高晶体硅太阳能电池转化效率的多尺度多层次纳米结构
a b s t r a c tHigh-performance antireflection structure is critical for enhancing the conversion efficiency of solar cells.One of the most effective antireflection techniques for solar cells is the introduction of nanostructuresto the cells. In this work, we prepared multiscaled hierarchical Er-doped ZnO nanostructures on theplasma enhanced chemical vapor deposited silicon nitride-coated texturized single crystalline siliconsolar cells for antireflection. The multiscaled hierarchical Er-doped ZnO nanostructures were needle-likenanotip arrays, and they were grown using the hydrothermal method. The dependence of microstruc-ture and antireflection performance of the multiscaled hierarchical Er-doped ZnO nanostructures on thegrowth time were studied. It was shown that longer growth time resulted in greater length and diameterfor the Er-doped ZnO nanostructures. For longer growth time, the needle-like tips of the multiscaledhierarchical Er-doped ZnO nanostructures were found to transform to flat tops, which greatly degradedtheir antireflection performance. An optimal growth time for the multiscaled hierarchical Er-doped ZnOnanostructures was determined, and a large enhancement in the photovoltaic performance of sc-Si solarcells was resulted.
