Dave Cahen
Bio-molecular Electronics: Electron Transport across Proteins
Perovskite solar cells
Department of Materials and Interfaces, Faculty of Chemistry, Weizmann Institute
Born and raised in the Netherlands, David Cahen is professor in the Materials & Interfaces dept. at the Weizmann Institute of Science, WIS, which he chaired between 2007-2012. He completed a B.Sc. in chemistry & physics at the Hebrew Univ. of Jerusalem (HUJ), a Ph.D. in materials and physical chemistry at Northwestern Univ., and did postdoctoral research in biophysics of photosynthesis at HUJ and WIS. After joining the WIS faculty DC started work on solar cells, notably developing a photoelectrochemical PV cell cum battery that has been rediscovered a few times since, and the solid-state and surface chemistry of solid-state solar cell materials. This expanded into studying chemical aspects of electronic materials and devices, including fundamental chemical limits to device miniaturization and device stability. The latter provided significant scientific bases for practical development of 2nd generation solar cells. His PV work today focuses on the basic materials and device chemistry and physics of perovskite halides and cells based on these.
In parallel he explored how and when defects in materials can actually improve material quality and device performance. His solar cell interests led to work on hybrid molecular/non-molecular materials and interfaces, and into molecular electronics, which evolved into other present activities, proteins as “dopable” and otherwise truly remarkable electronic materials. Honors in the past decade include the 2008 Landau (national) prize for Chemistry, the Kolthoff prize from the Technion (2009) and the 2012 Israel Chem, Soc. Prize for excellence, for research on alternative energy sources. He is a fellow of the AVS (2011) and the MRS (2014).
He directs the WIS’ campus-wide Alternative Sustainable Energy Research Initiative and holds the Rowland and Sylvia Schaefer Professorial Chair in Energy Research.
With D. Ginley he edited the MRS/Cambridge Un. Press textbook on Fundamentals of Materials for Energy and Environmental Sustainability. They also founded “MRS Energy & Sustainability, a review journal”, both part of his activities in “Energy & Sustainability” education.

Olindo Isabella
Photonic Nanostructures and Photovoltaic Devices:
1. Classical 4n2 absorption limit explained and demonstrated
2. Pushing the limit: light absorption in thin films
Photovoltaic Materials and Devices, EWI Faculty - Delft University of Technology
Olindo's areas of expertise are (i) opto-electrical modelling, (ii) characterization and implementation of advanced light management techniques in thin-film and wafer-based silicon solar cells, (iii) accurate energy yield prediction of custom and horizon-blocked PV systems. He was one of the pioneers to realize thin-film silicon solar cells on periodic gratings. He was the first to propose the concept of modulated surface textures which enable efficient light trapping over broad spectrum. He also successfully fabricated thin-film silicon solar cells with dielectric distributed Bragg reflectors, which can avoid plasmonic absorption losses in metallic reflectors. He contributed to experimentally demonstrate the classical 4n2 absorption limit and to fabricate a high performance omni-directional dielectric reflector. Recently he has been working on coupled optical and electrical modelling of optically complex structures such as multi-junction solar cells and interdigitated back contacted crystalline silicon solar cells. He is currently involved in the research of light management techniques applied to thin-film silicon, BaSi2, CIGS solar cells and transfer of such techniques to thin crystalline silicon wafer-based solar cells. Alongside with his research and development of high efficiency wafer-based silicon solar cells, Olindo is responsible for the PV Laboratory and gives lectures on PV systems. He is co-chair of Optics for Solar Energy conference within the OSA Light, Energy and the Environment Congress 2017 and of Silicon for Photovoltaics symposium within the 2017 MRS Fall Meeting. |

Pere Roca i Cabarrocas
Silane plasmas: a wonderful toolbox for the synthesis of nanomaterials
LPICM, Ecole Polytechnique
We design and develop new electrical and optoelectronic devices, covering the fields of solar energy harvesting and storage, innovative sensors based on nanomaterials, and large-area electronic devices. Our research strategy is based on a bobom-up approach, wherein the optimization of materials and processes relies on in-situ real- time diagnostic techniques developed in- house, backed up with ex-situ characterization and numerical modeling. In particular the laboratory has developed innovative optical characterization techniques such as Mueller polarimetry, which we apply to thin lms for microelectronics as well as to biomedical applications such as the diagnosis of cancer tissues. Tip Enhanced Raman Spectroscopy (TERS) has also been recently developed to characterize nano-objects (nanowires, nanotubes, and graphene) and successfully transferred to industry. |

Roland Wiesendanger
Revealing spin structures with atomic resolution:
1) Magnetism on the Nanoscale: From the Smallest Building Block Units to Model-Type Atomic-Scale Spintronic Devices.
2) The Exciting Physics of Bottom-Up Constructed Atomic Spin Chains on a Metallic Substrate.
Department of Physics, University of Hamburg
Revealing spin structures with atomic resolution is of central importance to many fields of modern condensed matter physics and spin-based technologies,
.g. nanomagnetism and spin-electronics, spin structures in high-Tc superconductors, or spin textures in quantum Hall ferromagnets. In the past twenty years
a fascinating technique was developed and continuously further improved by Roland Wiesendanger and his team members at the Universities of Basel (Switzerland)
and Hamburg (Germany), which allows for the first time the atomic scale visualization of spin structures and the investigation of the spin- and spatially-resolved electronic
structure down to the atomic level. As a result, structural, local electronic, and magnetic properties of condensed matter can now be correlated down to the atomic scale.
Moreover, Roland Wiesendanger and coworkers could recently demonstrate the first all-spin logic operations on the atomic scale (Science 332, 1062 (2011)).
Roland Wiesendanger has performed pioneering work on spin-polarized scanning tunneling microscopy and magnetic exchange force microscopy, which has made it possible to study magnetism at the level of individual atoms and investigate the atomic-scale spin structure of condensed matter.
R. Wiesendanger is professor of experimental physics at the University of Hamburg and head of the Interdisciplinary Nanoscience Center Hamburg. He also heads the Collaborative Research Center “Magnetism from the Single Atom to the Nanostructure” based at the German Research Foundation.
