Mechanical integrity of hybrid indium-free electrodes for flexible devices

Christophe Ballif, Yves Leterrier, Monica Morales Masis, Ali Dabirian, Fabien Paul Jacques Dauzou

Maintaining electrical conductivity, optical transparency, and mechanical integrity against bending and stretching are key requirements for flexible transparent electrodes. Transparent conducting oxides (TCOs) are widely used thin film electrodes in optoel ...

Semi-transparent perovskite solar cells for tandems with silicon and CIGS

Michael Graetzel, Norman Pellet, Julian Burschka

A promising approach for upgrading the performance of an established low-bandgap solar technology without adding much cost is to deposit a high bandgap polycrystalline semiconductor on top to make a tandem solar cell. We use a transparent silver nanowire e ...

Royal Society of Chemistry2015

Due to advantages such as mechanical flexibility, light weight and the prospect to use low-cost roll-to-roll manufacturing processes, organic semiconductors have been widely investi-gated in many application areas as alternatives for their inorganic counte ...

Environmental stability of high-mobility indium-oxide based transparent electrodes

Christophe Ballif, Stefaan De Wolf, Monica Morales Masis, Ali Dabirian, Thanaporn Tohsophon

Large-scale deployment of a wide range of optoelectronic devices, including solar cells, critically depends on the long-term stability of their front electrodes. Here, we investigate the performance of Sn-doped In2O3 (ITO), H-doped In2O3 (IO:H), and Zn-dop ...

Amer Inst Physics2015

The embodiments described herein provide an electrochromic device. In an exemplary embodiment, the electrochromic device includes (1) a substrate and (2) a film supported by the substrate, where the film includes transparent conducting oxide (TCO) nanostru ...

Perovskite Solar Cells Based on Nanocolumnar PlasmaDeposited ZnO Thin Films

Michael Graetzel, Mohammad Khaja Nazeeruddin, Francisco Javier Ramos Mellado

ZnO thin films having a nanocolumnar microstructure are grown by plasma-enhanced chemical vapor deposition at 423 K on pre-treated fluorine-doped tin oxide (FTO) substrates. The films consist of c-axis-oriented wurtzite ZnO nanocolumns with well-defined mi ...

The present invention provides a solid state heterojunction solar cell comprising a transparent conducting support layer (2,3), on which a nanostructured, surface-increasing scaffold structure is provided, wherein an organic-inorganic perovskite layer (4) ...

2014

Polycrystalline zinc oxide (ZnO) films, prepared by low-pressure chemical vapor deposition are investigated in this thesis. ZnO belongs to the class of transparent conductive oxide materials, as it is transparent to light from the visible to the near-infra ...

EPFL2013

Dye-sensitized solar cells (DSC) are a new class of molecular photovoltaics that mimics the natural photosynthesis, for the direct conversion of sunlight into electricity. A typical DSC is a sandwich of a dye sensitized nanoparticle TiO2 film and a catalys ...
