| 摘要: 以卟啉分子H2-pTCPP作为基础染料，通过配位自组装的方法将天线分子S3修饰到染料结构中。结果表明经天线分子修饰后染料敏化太阳能电池器件的整体性能得到了极大的改善。天线效应有效地提高了器件的光子捕获能力，光电流得到了显著的提高，并且电荷复合行为也得到了明显的抑制。基于H2-pTCPP的电池器件显示了1.18%的转换效率，而经过天线分子修饰后的Mn-pTCPP+S3显示了2.64%的转换效率，性能提高了1.2倍。 |

| Abstract: Using the porphyrin molecule H2-pTCPP as a basic dye, we modified antenna molecule S3 into dye structure by coordination self-assembly method. The results show that the overall performance of the device has been greatly improved after the modification of antenna molecule. The antenna effect effectively improves the light-harvesting ability and the photocurrent of the device, in addition, the charge recombination is obviously reduced. The device based on H2-pTCPP showed a PCE of 1.18%, and the device based on Mn-pTCPP+S3 showed a PCE of 2.64%. So, the overall performance of the device is increased by 1.2 times. |
