| 摘 要： | 制备了石墨炔掺杂poly(3-hexylthiophene):6,6] -phenyl-C61-buytyric acid methyl ester活性层的聚合物光伏器件.研究了石墨炔不同掺杂比例对光伏器件的短路电流及开路电压的影响.结果表明:石墨炔良好的电荷传输特性及二维平面结构可以改善活性层的互穿网络结构,增加电荷收集和传输的通道,从而提高器件的短路电流.在2.5％的掺杂比例下,短路电流提高了1.4 mA/cm2,能量转化效率提高了 35％,并且对不同的退火温度和退火时间经行了研究,发现最佳的退火温度为150℃.

| Abstract: | The paper introduced graphdiyne material in poly （3-hexylthiophene） / 6, 6] -phenyl-C61- buytyric acid methyl ester bulk-heterojunction solar cells. Investigate the influence of different graphdiyne doping ratio on the short circuit current （Jsc） and open circuit voltage （Voc）. The results suggest that high charge transport capability and two-dimensional structure of graphdiyne can improve the percolation paths in the active layer and enhance the collection of charge. The cell with 2.5 wt% graphdiyne exhibits an enhanced Jsc by 1.4 mA/cm2 and the highest PCE （2.98%）, which is 35% higher than that of the cell without graphdiyne doping. And the different annealing temperature and time also been investigated. |
