摘要：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%.
In this paper, bulk heterojunction solar cells with poly-(3-hexylthiophene) (P3HT): [6,6]-phenyl-C61-butyric-acid-methyl-ester (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% DMSO-modified-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%.
