【摘要】 在各种有机聚合物太阳电池活性层材料中,聚苯并二噻吩(PTB7)与富勒烯衍生物(PCBM)的共混材料所制作的电池取得现有单层体相异质结太阳电池领域中最好的光电转换效率。本实验在空气环境中制作结构为ITO/PFN/PTB7∶PC61BM/Mo O3/Al的反型有机聚合物太阳电池,对制作过程中溶液处理、薄膜干燥方式和活性层厚度控制等步骤进行不同条件的对比;并运用紫外可见吸收光谱和J-V曲线测试等方法研究具体制作步骤对太阳电池性能的影响;最后通过测试电池放置不同时间的J-V特性曲线,证明该反型电池在空气中具有良好的稳定性。更多还原

【Abstract】 Kinds of polymer materials have been investigated in study of polymer solar cells,among which the solar cellusing PTB7 as donor and PCBM as acceptor has gained efficiency of more than 9% and it is the best up to now in the bulkheterojunction solar cells. In our experiments,the inverted polymer solar cell with a construction of ITO/PFN/PTB7∶PC61BM/Mo O3/Al has been fabricated and characterized. The contrast tests for different solution concentrations,dryingmethods and filtering or not have been implemented to study their impacts on the performance of solar cells via UV-Visspectra and J-V curves and the stability of the cell was demonstrated as well.更多还原
