Abstract

A photoanode material ZnO nanoflower (ZNFs) for efficient dye-sensitized solar cell (DSSC) was prepared. This unique structure can significantly increase the specific surface area and amount of light absorption, leading to a higher short-circuit current density. Furthermore, ZNFs resulted in closer spacing between the nanorods and more direct conduction paths for electrons, leading to higher open-circuit voltage. The overall promising power conversion efficiency of 5.96% was obtained with photoanodes of 8.5 μm thickness. This work shows that ZNFs is an attractive material and has good potential for application in high efficiency ZnO-based DSSCs.

摘要

制备了一种用于高效染料敏化太阳能电池（DSSC）的光阳极材料氧化锌纳米花（ZNFs）。这种独特的结构可以显著增加比表面积和光吸收量，从而导致更高的短路电流密度。此外，ZNFs使纳米棒之间的间距更近，电子的传导路径更直接，从而导致更高的开路电压。使用厚度为8.5μm的光阳极获得了总体上有前景的5.96%的功率转换效率。这项工作表明ZNFs是一种有吸引力的材料，在基于氧化锌的高效DSSC中具有良好的应用潜力。
