제목 Easily Attainable Phenothiazine-Based Polymers for Polymer Solar Cells: Advantage of Insertion of S,S-Dioxides into its Polymer for Inverted Structure Solar Cells
초록 PPTDTBT and PPTDTBT-SS are fully characterized by UV-vis absorption, electrochemical cyclic voltammetry, X-ray diffraction (XRD), and DFT theoretical calculations. We find that the maximum absorption of PPTDTBT is not only markedly red-shifted with respect to that of PPTDTBT-SS but also its band gap as well as molecular energy levels are readily tuned by the insertion of S,S-dioxides into the polymer. The main interest is focused on the electronic applications of the two polymers in organic field-effect transistors (OFETs) as well as conventional and inverted polymeric solar cells. PPTSTBT is a typical p-type polymer semiconductor for OFETs and conventional PSCs based in this polymer and PC71BM show a power conversion efficiency (PCE) of 1.69%. In case of PPTDTBT-SS, the devices characteristics result in: 1 order of magnitude higher hole mobility than that obtained with PPTDTBT ans improved performance of the inverted PSCs (1.22%), compared to its conventional devices.
