Zr-doped indium oxide electrodes: Annealing and thickness effects on microstructure and carrier transport

Christophe Ballif, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Mathieu Gérard Boccard, Monica Morales Masis, Oscar Esteban Rucavado Leandro, Federica Landucci

Zr-doped indium oxide (In2O3:Zr) has been shown to satisfy the requirements of low resistance, wide band gap, and high infrared transmittance for application as a front contact in broadband solar cells. However, the reduction of indium usage in front of tr ...

Toward an alternative approach for the preparation of low-temperature titanium dioxide blocking underlayers for perovskite solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Kazuteru Nonomura, Lichen Zhao, Su Htike Aung

The anodic electrodeposition method is investigated as an alternative technique for the preparation of a titanium oxide (TiO2) blocking underlayer (UL) for perovskite solar cells (PSCs). Extremely thin Ti-IV-based films are grown from aqueous acidic titani ...

High-temperature annealing effects on molybdenum-silicon contact substrate for vertically structured silicon quantum-dot solar cells

Chien-Jen Yang

This paper studies the applicability of sputtered Molybdenum (Mo) thin films on silicon wafers (Mo-Si) to act as contact substrates for vertically structured Si quantum-dot (QD) solar cells. The compatibility of Mo-Si contact substrate with Si QD material ...

Numerical Simulation of Temperature Dependence of MoOx Based SHJ Solar Cell

Christophe Ballif, Philipp Friedrich Hermann Löper, Stephanie Essig

Transition metal oxides based high efficiency silicon heterojunction (SHJ) solar cells have emerged as promising candidate due to their low manufacturing cost and avoidance of poisonous dopant gases. Temperature dependent J V curves in such solar cells cou ...

Bacterial iron reduction and biogenic mineral formation for the stabilisation of corroded iron objects

Julien Maillard, Arnaud Michel Gelb

Exploiting bacterial metabolism for the stabilisation of corroded iron artefacts is a promising alternative to conventional conservation-restoration methods. Bacterial iron reduction coupled to biogenic mineral formation has been shown to promote the conve ...

Chromate Resistance Mechanisms in Leucobacter chromiiresistens

Rizlan Bernier-Latmani, Elena Suvorova Buffat

Chromate is one of the major anthropogenic contaminants on Earth. Leucobacter chromiiresistens is a highly chromate-resistant strain, tolerating chromate concentrations in LB medium of up to 400 mM. In response to chromate stress, L. chromiiresistens forms ...

Post-Sputtering Heat Treatments of Molybdenum on Silicon Wafer

Chien-Jen Yang

This paper investigated the property evolutions of Mo thin films that were subjected to post-sputtering heat treatments from 700 degrees C to 1100 degrees C. It was found that, after annealing, the use of Si wafers eliminated crack formations found in prev ...

Molybdenum Disulfide (MoS2) Nanoelectromechanical Resonators With On-Chip Aluminum Nitride (AlN) Piezoelectric Excitation

Luis Guillermo Villanueva Torrijo, Tom Larsen, Muhammad Faizan

We report on the first experimental demonstration of vibrating two-dimensional nanoelectromechanical systems (2D NEMS) with on-chip piezoelectric excitation. Combining a wafer-scale aluminum nitride (AlN) thin film technology with an all-dry transfer techn ...
