One-step fabrication of large-scaled indium tin oxide/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)/poly(3-hexylthiophene-2,5-diyl):[6,6]-phenyl-C61-butyric acid methyl ester multi-layered structure

摘要

A technique is established for fabricating a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)/ poly(3-hexylthiophene-2,5-diyl):[6,6]-phenyl-C61 -butyric acid methyl ester (PEDOT:PSS/P3HT:PCBM) multi-layered structure in one step by transferring a continuous P3HT:PCBM solid film floating on PEDOT:PSS solution onto an indium tin oxide/glass substrate with a size of 2.5 × 1.5 cm~2. This structure can be obtained under simple experimental conditions and can be fabricated over a large area. Preliminary testing shows that the prepared structure can yield a photovoltaic effect.
