为了提高聚合物载流子迁移率,本文对图案化聚合物聚3,4乙撑噻吩/聚苯乙烯磺酸盐(PEDOT∶PSS)作为半导体聚合物的基底对载流子迁移率的影响进行研究。以聚二甲基硅氧烷(PDMS)为模板,利用基于毛细力原理的软压印技术,使硬度系数很高的聚合物PEDOT∶PSS形成图案化结构。此压印方法可形成大面积高保真的图案,且适合工业化生产。阐述了图案化PEDOT∶PSS可增加与活性层的接触面积,从而缩短聚合物载流子的迁移路径,有效地提高了聚合物载流子的迁移率。同时图案化结构散射入射光进入活性层,促进活性层光的吸收,从而提高了光电流。最后,本文将图案化 PEDOT∶PSS 作为电极应用到有机太阳能电池聚3已基噻吩与富勒烯衍生物(P3 HT∶PCBM)共混体系中,对其研究发现图案化后的PEDOT∶PSS能有效地提高了太阳能电池P3 HT∶PCBM共混体系的能量转换效率。

In order to improve the carrier mobility of polymer,we study the influence of the carrier mobility of the semiconductor polymer with patterned poly(3,4-ethylene thiophene/polystyrene sulfonate(PEDOT∶PSS)as substrate.In this work,we fabricated the patterned PEDOT∶PSS film with high fidelity and large area using the Polydimethylsiloxane (PDMS)as the soft template.The soft lithography technology based on the capillary force was adopted due to the high hardness of the PEDOT∶PSS.In addition,this soft lithography technology is suitable for commercial process.Here we expound the patterned PEDOT∶PSS can increase its contact areas with the active layer,consequently shorten the pathway of the carrier and effectively enhance the carrier mobility.At the same time,the incident light into the active layer can promote the light absorption of active layer with the patterned structure scattering,which efficiently enhance the photocurrent.In the end,the patterned PEDOT∶PSS was applied to organic solar cells with poly 3-hexyl thiophene and fullerene derivative (P3 HT∶PCBM)blends mixture as electrodes.We found energy conversion efficiency of solar cell (P3 HT∶PCBM)blend system with the patterned PEDOT∶PSS was increased.
