A one-step low temperature processing route for organolead halide perovskite solar cells.

Chemical communications (Cambridge, England) 49:72 (2013) 7893-7895

Abstract:

Organolead trihalide perovskite solar cells based upon the co-deposition of a combined Al2O3-perovskite layer at T < 110 °C are presented. We report an average PCE = 7.2% on a non-sintered Al2O3 scaffold in devices that have been manufactured from a perovskite precursor containing 5 wt% Al2O3 nanoparticles.

Color in the corners: ITO-free white OLEDs with angular color stability.

Advanced materials (Deerfield Beach, Fla.) 25:29 (2013) 4006-4013

Authors:

Whitney Gaynor, Simone Hofmann, M Greyson Christoforo, Christoph Sachse, Saahil Mehra, Alberto Salleo, Michael D McGehee, Malte C Gather, Björn Lüssem, Lars Müller-Meskamp, Peter Peumans, Karl Leo

Abstract:

High-efficiency white OLEDs fabricated on silver nanowire-based composite transparent electrodes show almost perfectly Lambertian emission and superior angular color stability, imparted by electrode light scattering. The OLED efficiencies are comparable to those fabricated using indium tin oxide. The transparent electrodes are fully solution-processable, thin-film compatible, and have a figure of merit suitable for large-area devices.

Charge density dependent mobility of organic hole-transporters and mesoporous TiO₂ determined by transient mobility spectroscopy: implications to dye-sensitized and organic solar cells.

Adv Mater 25:23 (2013) 3227-3233

Authors:

Tomas Leijtens, Jongchul Lim, Joël Teuscher, Taiho Park, Henry J Snaith

Abstract:

Transient mobility spectroscopy (TMS) is presented as a new tool to probe the charge carrier mobility of commonly employed organic and inorganic semiconductors over the relevant range of charge densities. The charge density dependence of the mobility of semiconductors used in hybrid and organic photovoltaics gives new insights into charge transport phenomena in solid state dye sensitized solar cells.
