【摘要】 共轭导电聚合物材料由于同时具有聚合物(塑料)优异的加工性和无机半导体的特性,将其应用在太阳能光电转换方面,制作大面积廉价光伏器件,提供可再生清洁能源,具有十分广阔的前景。本文综述了聚合物太阳电池材料及器件的发展现状。在光电领域,聚对苯撑乙炔(PPV)及其衍生物是近年来研究得最广泛,最深入的聚合物材料。而对其光伏性质的研究,对于寻找新的聚合物太阳电池材料,将是一个很有意义的工作。本文首次研究了吡唑啉衍生物与对苯撑乙炔的共聚物(PSPY12)的光伏性质,制作的光伏器件结构为:ITO/PSPY12+TiO2/Al,在AM1.5的模拟太阳光照射下,器件的开路电压23mV,短路电流为0.002 mA,填充因子为0.3718,转换效率为7.8×10-6 %。在对香豆素封端的MEH-PPV(CT-MEH-PPV)的光伏性质研究中,采用ITO/CT-MEH-PPV(100 nm)/C60(35 nm)/Al(70 nm)的器件结构,在AM1.5的模拟太阳光照射下,得到了0.3 %的能量转换效率,开路电压为489 mV,短路电流为1.63 mA,填充因子为0.36。为进一步的材料修饰及器件优化提供了条件。更多还原

【Abstract】 Conjugated conductive polymeric materials have attracted much interest all over the world beacause their easily manufacturing and semiconductor properties of inorganic materials. Use them in solar cells to fabricating large scale and cheap PV devices are encouraging. In this dissertation, the development of polymer solar cells materials and their devices was reviewed, especially for Poly(phenylene vinylene) and bulk heterojunction devices.A single layer organic solar cell with blends of a PSPY12 and titanium isopropoxide, sandwiched between two electrodes, had been fabricated and measured. The fill factor of the solar cell was 0.3718 and had a power conversion efficiency of 7.88×10-6 % when illuminated with white light at AM=1.5. The open circuit voltage, the short circuit current of the single device was 23 mV and 0.002 mA respectively.With the device structure of ITO/CT-MEH-PPV(100 nm)/C60(35 nm)/Al (70 nm) ,Under illuminated with white light at AM=1.5 , the fill factor of the solar cell was 0.36 and had a power conversion efficiency of 0.3 %, The open circuit voltage, the short circuit current was 489 mV and 1.63 mA respectively.更多还原
