Surface passivation and functionalisation for mass photometry

Suliana Manley, Jenny Sülzle, Laila Abdelaziz Abdelmoniem Elfeky

Interferometric scattering (iSCAT) microscopy enables the label-free observation of biomolecules. Consequently, single-particle imaging and tracking with the iSCAT-based method known as mass photometry (MP) is a growing area of study. However, establishing ...

An Advanced Alkaline Al-Air Fuel Cell Using L-Ascorbic Acid Interface Layer upon Al Anode via Gradient Anti-corrosion

Pengfei Zhang, Manhui Wei

Al metal is considered as an excellent anode material for metal-air fuel cells thanks to the advantages in terms of capacity and energy density. However, the anodic parasitic corrosion has brought great obstacles to the performance breakthrough of Al-air f ...

A colloidal aqueous electrolyte modulated by oleic acid for durable zinc metal anode

Kangning Zhao, Xu Zhang, Di Yang

Continuous dendrites growth, as well as corrosion and side reactions of Zn metal anode seriously hinder the development of aqueous zinc ion batteries. To address these issues, oleic acid (OA) is dispersed into a 2 M ZnSO4 solution to form a novel colloidal ...

Characterization and Development of Fired Passivating Contacts for Silicon Solar Cells

Mario Joe Lehmann

One of the key elements to improve mainstream crystalline silicon (c-Si) solar cell performance is surface passivation, which is at the center of the ongoing transition from cells with direct silicon-metal contacts to full area passivating contacts. In the ...

Modeling Current Transients in a Reciprocal Motion Tribocorrosion Experiment

Stefano Mischler, Anna Neus Igual Muñoz, Shoufan Cao

Tribocorrosion of passivating metals is a dynamic phenomenon causing degradation of materials by a combination of mechanical wear and electrochemical dissolution. The mechanical action typically produces a local removal of particles, metal as well as oxide ...

A Crevice Corrosion Model for Biomedical Trunnion Geometries and Surfaces Feature

Stefano Mischler, Anna Neus Igual Muñoz, Angela Bermudez Castañeda

Modular hip joint implants were introduced in arthroplasty medical procedures because they facilitate the tailoring of patients’ anatomy, the use of different materials in one single configuration, as well as medical revision. However, in certain cases, su ...

Surface Reconstruction Engineering with Synergistic Effect of Mixed‐Salt Passivation Treatment toward Efficient and Stable Perovskite Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Ulf Anders Hagfeldt, Filippo de Angelis, Hui-Seon Kim, Bowen Yang, Jiajia Suo, Yeonju Kim

Surface passivation treatment is a widely used strategy to resolve trap-mediated nonradiative recombination toward high-efficiency metal-halide perovskite photovoltaics. However, a lack of passivation with mixture treatment has been investigated, as well a ...

Phosphine Oxide Derivative as a Passivating Agent to Enhance the Performance of Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Hiroyuki Kanda, Mounir Driss Mensi, Hobeom Kim, Cansu Igci, Tom Theodorus Antonius Lummen, Aron Joel Huckaba, Valentin Ianis Emmanuel Queloz, Aditya Gilra, Albertus Adrian Sutanto

Defects of metal-halide perovskites detrimentally influence the optoelectronic properties of the thin film and, ultimately, the photovoltaic performance of perovskite solar cells (PSCs). Especially, defect-mediated nonradiative recombination that occurs at ...

Defect Passivation via the Incorporation of Tetrapropylammonium Cation Leading to Stability Enhancement in Lead Halide Perovskite

Anurag Krishna

Improving the performances of photovoltaic (PV) devices by suppressing nonradiative energy losses through surface defect passivation and enhancing the stability to the level of standard PV represents one critical challenge for perovskite solar cells. Here, ...

Rapid Performance Optimization Method for Photoelectrodes

Sophia Haussener, Yannick Kenneth Gaudy

We report the development of a rapid method for the performance optimization of photoelectrodes. The method requires as an input incident photon-to-current efficiency (IPCE) measurements of a material at two or more wavelengths, an estimation of the comple ...
