摘要: Fully regioregular poly[(2-methoxy-5-(3′,7′-dimethyloctyloxy))-1,4-phenylenevinylene]s (MDMO-PPVs) synthesized by the Horner route were utilized for polymer photovoltaic devices, and their performance was compared with that of regiorandom MDMO-PPVs. The mixture films MDMO-PPVs 1-[3-(methoxycarbonyl)propyl]-1-phenyl-(6,6)-C61 (PCBM) successfully fabricated spin coating using a hot chlorobenzene solution. Significant improvements in fill factor (FF) short circuit current (ISC) observed devices MDMO-PPV those MDMO-PPV. A power conversion efficiency 3.1% achieved under AM1.5 illumination, which is highest reported PPV:PCBM system so far, whereas only 1.7% It concluded both higher hole mobility resulting from crystallinity better mixing ...
