Submitted for the MAR14 Meeting of The American Physical Society Improving the performance of All-Polymer Solar Cells YAN JIN, FEI YU, VIKRAM KUPPA, Univ of Cincinnati — We find that the power conversion efficiency (PCE) of photovoltaic devices based on conjugated polymer blends is dramatically improved by the addition of small quantities of pristine -unmodifiedgraphene in the active layer. The...
Recently, cobalt redox electrolyte mediators have emerged as a promising alternative to the commonly used iodide/triiodide redox shuttle in dye-sensitized solar cells (DSCs). Here, we report the successful use of a new quasi-liquid, polymer-based electrolyte containing the Co(3+)/Co(2+) redox mediator in 3-methoxy propionitrile solvent in order to overcome the limitations of high cell resistanc...
Due to their high transparency, electrodes fabricated from conductive polymers are often implemented in semitransparent organic solar cells. Opaque cells usually employ metal back with reflectivity for best photon confinement the light-harvesting layer. Herein, a bilayer electrode comprising and nanofoamed poly(methyl methacrylate) (PMMA) is investigated, latter of which creates diffuse reflect...
