  1. Lead Iodide Perovskite Sensitized All-Solid-State Submicron Thin Film Mesoscopic Solar Cell with Efficiency Exceeding 9%Scientific Reports · 2012 · 8,113 citations

    We report on solid-state mesoscopic heterojunction solar cells employing nanoparticles (NPs) of methyl ammonium lead iodide (CH(3)NH(3))PbI(3) as light harvesters. The perovskite NPs were produced by reaction of methylammonium iodide with PbI(2) and deposited onto a submicron-thick mesoscopic TiO(2) film,…

  2. Long-Range Balanced Electron- and Hole-Transport Lengths in Organic-Inorganic CH 3 NH 3 PbI 3Science · 2013 · 6,919 citations

    Low-temperature solution-processed photovoltaics suffer from low efficiencies because of poor exciton or electron-hole diffusion lengths (typically about 10 nanometers). Recent reports of highly efficient CH3NH3PbI3-based solar cells in a broad range of configurations raise a compelling case for understanding the…

  4. Porphyrin-Sensitized Solar Cells with Cobalt (II/III)–Based Redox Electrolyte Exceed 12 Percent EfficiencyScience · 2011 · 5,982 citations

    The iodide/triiodide redox shuttle has limited the efficiencies accessible in dye-sensitized solar cells. Here, we report mesoscopic solar cells that incorporate a Co((II/III))tris(bipyridyl)-based redox electrolyte in conjunction with a custom synthesized donor-π-bridge-acceptor zinc porphyrin dye as sensitizer (designated YD2-o-C8). The…

  5. Cesium-containing triple cation perovskite solar cells: improved stability, reproducibility and high efficiencyEnergy & Environmental Science · 2016 · 5,471 citations

    Today's best perovskite solar cells use a mixture of formamidinium and methylammonium as the monovalent cations. With the addition of inorganic cesium, the resulting triple cation perovskite compositions are thermally more stable, contain less phase impurities and are less sensitive…

  6. Light-Induced Redox Reactions in Nanocrystalline SystemsChemical Reviews · 1995 · 5,358 citations

    A review with 156 refs. on interfacial electron transfer reactions in colloidal semiconductor solns. and thin films and their application for solar light energy conversion and photocatalytic water purifn. Some of the topics discussed include; optical and electronic properties of…

  7. Incorporation of rubidium cations into perovskite solar cells improves photovoltaic performanceScience · 2016 · 3,726 citations

    Improving the stability of perovskite solar cells Inorganic-organic perovskite solar cells have poor long-term stability because ultraviolet light and humidity degrade these materials. Bella et al. show that coating the cells with a water-proof fluorinated polymer that contains pigments to…

  8. Solar Energy Conversion by Dye-Sensitized Photovoltaic CellsInorganic Chemistry · 2005 · 3,388 citations

    The quality of human life depends to a large degree on the availability of energy. This is threatened unless renewable energy resources can be developed in the near future. Chemistry is expected to make important contributions to identify environmentally friendly…

  9. A hole-conductor–free, fully printable mesoscopic perovskite solar cell with high stabilityScience · 2014 · 3,052 citations

    We fabricated a perovskite solar cell that uses a double layer of mesoporous TiO2 and ZrO2 as a scaffold infiltrated with perovskite and does not require a hole-conducting layer. The perovskite was produced by drop-casting a solution of PbI2, methylammonium…

  10. Combined Experimental and DFT-TDDFT Computational Study of Photoelectrochemical Cell Ruthenium SensitizersJournal of the American Chemical Society · 2005 · 2,749 citations

    We report a combined experimental and computational study of several ruthenium(II) sensitizers originated from the [Ru(dcbpyH(2))(2)(NCS)(2)], N3, and [Ru(dcbpyH(2))(tdbpy)(NCS)(2)], N621, (dcbpyH(2) = 4,4'-dicarboxy-2,2'-bipyridine, tdbpy = 4,4'-tridecyl-2,2'-bipyridine) complexes. A purification procedure was developed to obtain pure N-bonded isomers of both types…

  11. Recent Advances in Sensitized Mesoscopic Solar CellsAccounts of Chemical Research · 2009 · 2,675 citations

    Perhaps the largest challenge for our global society is to find ways to replace the slowly but inevitably vanishing fossil fuel supplies by renewable resources and, at the same time, avoid negative effects from the current energy system on climate,…

    The dye-sensitized nanocrystalline injection solar cell employs transition metal complexes for spectral sensitization of mesoporous TiO(2) films together with suitable redox electrolytes or amorphous organic hole conductors. Light harvesting occurs efficiently over the whole visible and near-IR range due to…
