【摘要】：太阳能作为一种可再生的清洁能源,取之不尽,用之不竭,而且不受地区限制,安全可靠,可大规模应用,已经得到世界各国的广泛关注,是各国科学家开发利用的新能源之一。而有机太阳能电池原材料来源广泛、廉价,具有较高的吸收系数和良好的光伏效应,制备工艺灵活简单,可在柔性衬底上制备,因此得到广泛关注。阳极缓冲层作为空穴传输层和电子阻挡层,是有机太阳能电池中不可或缺的一部分,能够大大改善器件性能。本文主要进行了以下几方面的研究:1.基于P3HT/PCBM的有机太阳能电池的相关工艺参数的研究:选用氯苯和二氯苯两种溶剂制备活性层前驱液,结果显示使用邻二氯苯作溶剂的器件效率达到1.66%,比使用氯苯作溶剂的器件高20%;在邻二氯苯中掺杂3%的1,8-二碘辛烷(DIO)得到的器件效率达到1.74%,高于不掺杂的器件效率的1.45%;P3HT/PCBM质量比分别为1:1和1:0.8,制备的器件效率分别为1.54%和1.65%;固定退火时间为20分钟,改变退火温度,结果表明,温度在130℃-150℃时,器件具有更高的转换效率,达到1.60%;设定退火温度130℃,改变退火时间,结论是退火时间为20分钟器件效率最高,达到1.75%;改变旋涂工艺中活性层的转速,分别为800、1100、1300、1600,其中转速1100RPM时器件效率最高,达到1.72%;改变阴极缓冲层(Li F)厚度,分别为0.5nm和1nm,结论是1nm器件性能更佳。2.基于PEDOT/PSS阳极缓冲层的有机太阳能电池研究:改变旋涂时PEDOT/PSS的转速来调节其厚度,转速分别为3000、4000和5000RPM,结果表明转速为4000时,器件效率最高达到1.69%;PEDOT/PSS掺杂体积比分别为2%、4%和6%的二甲亚砜,结果显示掺杂4%的器件转换效率最高达到1.75%;PEDOT/PSS中掺杂体积比分别为5%、10%和15%异丙醇,结果表明掺杂10%异丙醇的器件具有更好的转换效率为1.7%。3.溶液法制备MoO3及其在有机太阳能电池中的应用研究:利用钼酸铵水解法制备MoO3前驱液,采用旋涂法制膜,分析薄膜成分和表面形貌,验证了MoO3作为阳极缓冲层在有机太阳能电池中的应用。本文研究了基于P3HT/PCBM的有机太阳能电池各项参数,基于PEDOT/PSS阳极缓冲层的有机太阳能电池研究,基于MoO3阳极缓冲层的制备及其在有机太阳电池中的应用研究。基于P3HT/PCBM的有机太阳能电池转换效率能够达到1.70%,基于PEDOT/PSS阳极缓冲层的有机太阳能电池转换效率能够达到1.75%。
[Abstract]:Solar energy as a renewable clean energy, inexhaustible, and not limited by regional restrictions, safe and reliable, can be used on a large scale, has been widely concerned about the world, It is one of the new energy sources developed by scientists all over the world. Organic solar cells have a wide range of raw materials, cheap, with high absorption coefficient and good photovoltaic effect, the preparation process is flexible and simple, can be prepared on flexible substrates, so it has been widely concerned. As the hole transport layer and the electron barrier layer, the anode buffer layer is an indispensable part of the organic solar cells, which can greatly improve the performance of the devices. This article mainly carries on the following several aspects of research: 1. Study on the technological parameters of organic solar cells based on P3HT / PCBM: chlorobenzene and dichlorobenzene were used to prepare active layer precursor. The results show that the device efficiency using o-dichlorobenzene as solvent is 1.66, which is 20% higher than that with chlorobenzene as solvent, and the device efficiency is 1.74% higher than that without doping 3% 1 ~ (8%) diiodooctane diol in o-dichlorobenzene. The mass ratio of P3HT / PCBM is 1:1 and 1: 0.8, the device efficiency is 1.54% and 1.65%, and the fixed annealing time is 20 minutes. The results show that when the annealing temperature is between 130 鈩，
