Charge extraction via graded doping of hole transport layers gives highly luminescent and stable metal halide perovskite devices
Michael Graetzel, Mohammad Ibrahim Dar, Mojtaba Abdi Jalebi, Zahra Andaji Garmaroudi
One source of instability in perovskite solar cells (PSCs) is interfacial defects, particularly those that exist between the perovskite and the hole transport layer (HTL). We demonstrate that thermally evaporated dopant-free tetra-cene (120 nm) on top of t ...
American Association for the Advancement of Science (AAAS)2019Can a Metal Surface Repel Electric Charges?
We show that the interaction between a surface and a charge packet moving parallel to it can become repulsive above a critical relativistic energy. We find that this is true for a lossless dielectric surface and also for a Drude metallic surface-in apparen ...
American Physical Society2012Characterisation of Low Impact Energy Induced Damage in Composite Plates with Embedded Optical Sensors
Fibre reinforced materials are increasingly employed in aerospace, naval and civil structures because of their low weight and high specific strength and stiffness. A major concern is the inherent susceptibility of composite laminates to barely visible dama ...
EPFL2011Charging phenomena in PEEM imaging and spectroscopy
Spectromicroscopy with the imaging technique of X-ray photoelectron emission microscopy (X-PEEM) is a microchemical analytical tool installed in many synchrotron radiation laboratories, and which is finding application in diverse fields of research. The me ...
