Organic light emitting diodes using magnesium doped organic acceptor as electron injection layer and silver as cathode 下载免费PDF全文
Organic light emitting diodes employing magnesium doped electron
acceptor 3, 4, 9, 10 perylenetetracarboxylic dianhydride
(Mg:PTCDA) as electron injection layer and silver as cathode were
demonstrated. As compared to Mg:Ag cathode, the combination of
the Mg:PTCDA layer and silver provided enhanced electron
injection into tris (8-quinolinolato) aluminium. The device with
1:2 Mg:PTCDA and Ag showed an increase of about 12% in the
maximum current efficiency, mainly due to the improved hole-electron
balance, and an increase of about 28% in the maximum power
efficiency, as compared to the control device using Mg:Ag
cathode. The properties of Mg:PTCDA composites were studied as
well. 相似文献

制备了由低聚合度的聚[2,6-(4,4-双-(2-乙基己基)-4H-环戊[2,1-b;3,4-b']双噻吩)-交替-4,7-(2,1,3-苯并噻二唑)](LDP-PCPDTBT)、[6,6]-苯基-C61-丁酸甲酯(PC61BM)和聚甲基丙烯酸甲酯(PMMA)组成的三组分共混薄膜,并通过加入溶剂添加剂(1,8-二溴辛烷,DBO)对体系进行了优化处理.研究发现,没有加入DBO时,LDP-PCPDTBT和PC61BM相在PMMA的基质中分别是无定形的和结晶的;加入DBO后,PMMA基质中LDP-PCPDTBT和PC61BM间的相分离过程得到优化,有机太阳能电池的能量转换效率相应提高了32.4%. 相似文献
