Polymer solar cells (PSCs) have notable advantages such as possibility of roll-to-roll mass production. However, there is existing issues of thickness-dependent charge transport layers in large area module. In this work, one of the perfluorosulfonic acids, ethanesulfonyl fluoride, 2-[1-[difluoro-[(trifluoroethenyl)oxy]methyl]-1,2,2,2-tetrafluoro-ethoxy]-1,1,2,2,-tetrafluoro-, with tetrafluoroethylene also known as Nafion is blended with the poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) for tuning the work function of electrodes. The films made with the blending of PEDOT:PSS and Nafion (P:N) are treated with concentrated sulfuric acid for a well-ordered crystalline structure in P:N electrodes. We fabricated hole transport layer free PSCs with P:N films as an anode. We confirmed the electrical and morphological properties of the P:N films with the various ratio of Nafion. |
