我们 poly 基于 regioregular 报导器官的太阳能电池(振荡) 的提高的表演(3-hexylthiophene )(P3HT ) 并且 methanofullerene [6,6 ] 苯基由在活跃的层把 dihydroxybenzene 用作添加剂的 C61 奶油的酸甲基酉旨(PCBM ) 混合。设备的电的特征上的添加剂的内容的效果被学习。有 0.2 wt% dihydroxybenzene 添加剂的设备在 AM 1.5G ( 100 mW/cm2 )的模仿的太阳的照明下面与 12.5 mA/cm2 , 0.65 V 的 V oc ,和66.6%的 FF 的 J sc 完成4.58%的最好的力量变换效率( PCE ),与有3.39%的 PCE 的控制设备相比(35%改进与控制设备相比)。XRD 测量表明添加剂的增加导致 P3HT 的结晶化并且建立好互连网络增加施主和领受人的接触区域,然后帮助收费有效地被转移到电极减少再结合的机会。所有证据显示 dihydroxybenzene 是可能的是能提高器官的体积异质接面太阳能电池的表演的有希望的新类型添加剂。
We report the enhanced performance of organic solar cells(OSCs) based on regioregular poly(3-hexylthiophene)(P3HT) and methanofullerene [6,6]-phenyl C61-butyric acid methyl ester(PCBM) blend by using dihydroxybenzene as additive in the active layer.The effect of the content of the additives on electrical characteristics of the device is studied.The device with 0.2 wt% dihydroxybenzene additive achieves the best power conversion efficiency(PCE) of 4.58% with Jsc of 12.5 mA/cm2,Voc of 0.65 V,and FF of 66.6% under simulated solar illumination of AM 1.5G(100 mW/cm2),compared with the control device with PCE of 3.39%(35% improvement compared with the control device).The XRD measurement reveals that the addition of additives induces the crystallization of P3HT and establishes good inter-network to increase the contact area of donor and acceptor,and then helps charge to be effectively transferred to the electrode to reduce the chance of recombination.All evidences indicate that the dihydroxybenzene is likely to be a promising new type additive that can enhance the performance of organic bulk heterojunction solar cells.
