我们已经开发出一种创新的结构,用于提高基于光纤的三维DSSC的性能,通过集成光纤/TiO 2-阵列的混合结构与圆柱形反电极。采用液相沉积法在光纤上生长了TiO 2纳米线阵列,并采用化学镀法在不锈钢毛细管内壁镀铂。三维染料敏化太阳能电池是通过在纤维结构上包覆管状结构而制成的。与平面照明几何形状相比,3D结构的效率提高了3.6倍。在最佳的纳米线长度(12 μm)下,绝对效率为6%。这项研究展示了一种新的方法,用于构建柔性和高效的基于纤维的3D太阳能电池,可以扩展到聚光太阳能电池。
We have developed an innovative structure for enhancing the performance of the fiber based 3D DSSC by integrating optical-fiber/TiO2-nanowire-arrays hybrid structures with cylindrical counterelectrodes. The TiO2nanowire arrays are grown on the optical fiber using liquid phase deposition method and platinum is coated on the inwall of stainless steel capillary tubes using electroless deposition. The 3D DSSC is made by sheathering the tube on the fiber structure. In comparison to planar illumination geometry, the efficiency for the 3D structure has been enhanced by a factor of 3.6. An absolute efficiency of 6% has been demonstrated at an optimal length of TiO2NWs (12 μm). This study demonstrates a new methodology for building flexible and high-efficient fiber based 3D solar cells that can be expanded to concentrating solar cells.
