利用纳米球光刻技术和金属蒸发技术制备了金属纳米网。金属纳米网具有精确控制的纳米结构，具有六边形排列的周期性圆孔，具有优异的均匀性。采用纳米金电极制备的P3HT:PCBM有机太阳能电池具有61%的填充系数和3.12%的功率转换效率。电磁仿真结果表明，金属纳米网的光学性能可以通过调整薄膜厚度、孔径和周期来优化。这些结果显示了金属纳米网作为有机太阳能电池透明电极的巨大潜力。
We have fabricated a metallic nanomesh using nanosphere lithography and metal evaporation. The metallic nanomesh has a precisely controlled nanostructure showing excellent uniformity with hexagonally arrayed periodic circular holes. A P3HT:PCBM organic solar cell, with the gold nanomesh electrode, demonstrates a high fill factor of 61% and a considerable power conversion efficiency of 3.12%. Electromagnetic simulation indicates that the optical properties of the metallic nanomesh can be optimized for organic photovoltaic devices by tuning the film thickness, hole diameter, and periodicity. These results show the promising potential of using a metallic nanomesh as the transparent electrode in organic solar cells.
