New metric for carrier selective contacts for silicon heterojunction solar cells
Mathieu Gérard Boccard, Jakub Holovsky
Heterojunction carrier selective contacts for solar cells have gained great attention because of the ability of these contacts to efficiently collect majority carriers while hindering the recombination of minority carriers, thus resulting in the highest re ...
PERGAMON-ELSEVIER SCIENCE LTD2022Optoelectronics based on the spin-valley physics of 2D materials
Two-dimensional (2D) materials are atomically thin crystals with exceptional mechanical, electrical and optical properties. Their unique characteristics originating from quantum confinement in the vertical dimension have attracted a strong interest for sci ...
EPFL2022Chemical Cell Surface Modification and Analysis of Nanoparticle-Modified Living Cells
Harm-Anton Klok, Tanja Thomsen
Cells are promising as carriers that can enhance the delivery of nanomedicines. Cells that carry nanomedicinal cargo, either immobilized on the cell surface or internalized, can allow for highly specific delivery and can enable the transport of nanomedicin ...
AMER CHEMICAL SOC2021Propelling the hydrogen economy: from chemical storage and delivery to utilization in biomass conversion
Since H2 is a non-polluting, inexhaustible, efficient, and sustainable energy carrier, it has been forecast to become one of the major carriers of energy in the future and is also essential in the production of feedstock chemicals derived from renewable ca ...
EPFL2021Lateral transport in silicon solar cells
Christophe Ballif, Gabriel Christmann, Mathieu Gérard Boccard, Jan Haschke
We investigate lateral charge carrier transport in crystalline silicon solar cells. Under typical operation illumination of high-efficiency solar cells, a significant population of electrons and holes exist in the silicon wafer, leading to a non-negligible ...
AIP2020Slow CH3NH3+ Diffusion in CH3NH3PbI3 under Light Measured by Solid-State NMR and Tracer Diffusion
Michael Graetzel, Joachim Maier, Alessandro Senocrate
We investigate methylammonium (MA) transport in MA lead iodide under illumination and show this, as in the dark, to be measurable but negligible when compared with the major carriers. H-1 and C-13 nuclear magnetic resonance (NMR) spectra show constant line ...
