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 ...

A multi-technique approach to study the microstructural properties of tin-based transparent conductive oxides

Federica Landucci

Transparent conductive oxides (TCOs) are semiconductor-like materials that exhibit high electrical conductivity and high optical transparency combined. They are adopted in various applications ranging from gas sensors, to electrochromic windows, to photovo ...

High performance amorphous Zn-Sn-O: impact of composition, microstructure, and thermal treatments in the optoelectronic properties

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

Zinc and tin oxides are both earth-abundant materials with demonstrated applicability as electrodes in several optoelectronic devices. The presence of grain boundaries in these polycrystalline films generally limits the electron mobility. By a combinatoria ...

Enhancing the optoelectronic properties of amorphous zinc tin oxide by subgap defect passivation: A theoretical and experimental demonstration

Christophe Ballif, Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Jakub Holovsky, Monica Morales Masis, Federica Landucci, Martial Duchamp, Oscar Esteban Rucavado Leandro

The link between sub-bandgap states and optoelectronic properties is investigated for amorphous zinc tin oxide (a-ZTO) thin films deposited by RF sputtering. a-ZTO samples were annealed up to 500 °C in oxidizing, neutral, and reducing atmospheres before ch ...
