在这份报纸,有 poly-(3-hexylthiophene )(P3HT ) 的体积异质接面太阳能电池:[6,6 ]-phenyl-C61-butyric-acid-methylester (PCBM ) 作为活跃的层并且 poly 修改了(3,4-ethylenedioxythiophene ) :poly (styrenesulfonate )(PEDOT : PSS ) 作为一个缓冲区,层被制作。缓冲区层被增加 1% ~ 5% dimethyl sulfoxide (DMSO ) 进 PEDOT 修改:在纺纱涂层前的 PSS 答案。修改 PEDOT 的传导性: PSS 和有修改 PEDOT 的太阳能电池的表演: PSS 被测量。修改 PEDOT 的最高的传导性: 有 4% DMSO 的 PSS 能完成 89.693 S/cm。有 PEDOT 的器官的太阳能电池的表演:4% DMSO 修改的 PSS 是最好。4% DMSO-modified-PEDOT : PSS 房间有力量变换 3.34% 的效率, 5.7 V 的 V oc, 14.56 mA/cm2 的 J sc 和 40.34% 的充满的因素(FF ) 。
In this paper,bulk heterojunction solar cells with poly-(3-hexylthiophene)(P3HT):[6,6]-phenyl-C61-butyric-acid-methylester(PCBM) as an active layer and modified poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS) as a buffer layer are fabricated.The buffer layer is modified by adding 1% to 5% dimethyl sulfoxide(DMSO) into PEDOT:PSS solution before spin-coating.The conductivity of modified PEDOT:PSS and the performance of solar cells with modified PEDOT:PSS are measured.The highest conductivity of modified PEDOT:PSS with 4% DMSO can achieve 89.693 S/cm.The performance of organic solar cell with PEDOT:PSS modified by 4% DMSO is the best.The 4% DMSOmodified-PEDOT:PSS cell has a power conversion efficiency of 3.34%,V oc of 5.7 V,J sc of 14.56 mA/cm 2 and filling factor(FF) of 40.34%.
